Abstract:

The common cuckoo has several host-specific races, each with a distinctive egg that tends to match its host's eggs. Here, we show that the host-race specializing on reed warblers also has a host-specific nestling adaptation. In playback experiments, the nestling cuckoos responded specifically to the reed warbler's distinctive ‘churr’ alarm (given when a predator is near the nest), by reducing begging calls (likely to betray their location) and by displaying their orange-red gape (a preparation for defence). When reed warbler-cuckoos were cross-fostered and raised by two other regular cuckoo hosts (robins or dunnocks), they did not respond to the different alarms of these new foster-parents. Instead, they retained a specific response to reed warbler alarms but, remarkably, increased both calling and gaping. This suggests innate pre-tuning to reed warbler alarms, but with exposure necessary for development of the normal silent gaping response. By contrast, cuckoo chicks of another host-race specializing on redstarts showed no response to either redstart or reed warbler alarms. If host-races are restricted to female cuckoo lineages, then chick-tuning in reed warbler-cuckoos must be under maternal control. Alternatively, some host-races might be cryptic species, not revealed by the neutral genetic markers studied so far.

Abstract:

AbstractThis study investigates male and female incubation ability in two monogamous Acrocephalus warblers with overlapping, equally sized territories and similar prey abundance. Given the longer breeding time window of the moustached warbler (A. melanopogon) compared with the reed warbler (A. scirpaceus), the trade-off between the need for biparental care and the cost of inefficient incubation is discussed. Hourly protocols and egg temperature measurements were analyzed with regard to four primary questions: male and female incubation ability, the role of environmental parameters, hatching success and the influence of male incubation on female time allocation. In both species, males increase egg temperature per minute at a slower rate than do females. There is no species difference in the percentage of incubation per hour for males (20%) or females (50%). Ambient temperature influences male incubation only in the moustached warbler during the early season (April) when male incubation correlates with hatching success. The male reed warbler shows daily temporal selectivity throughout the breeding season, increased incubation during rainfall, and no correlation with hatching success. In both species, females receive direct benefits of increased foraging time through male incubation. However, only the female reed warbler adjusts her incubation duration to previous male incubation. Thus, female reed warblers maximise the male component and thereby reduce the total incubation phase with high male effort whereas the incubation phase is increased with above average male effort in the moustached warbler.

Abstract:

Pigment disorders such as albinism, leucism and progressive greying, which cause the absence of melanin pigments in all or parts of the plumage and bare parts, have been reported in many wild bird populations including Acrocephalus warblers. Basra Reed Warbler Acrocephalus griseldis (Hartlaub, 1891) is a restricted-range species confined to the extensive reed beds of Mesopotamian marshes. It is listed as Endangered due to breeding habitat degradation, water scarcity and climate change. In April 2018, a partly white plumaged Basra Reed Warbler was sighted in Central Marshes in southern Iraq. This is the first report of such a plumage aberration in this species. The nature of the aberration involved an intraspecific/interspecific behavior of the white plumaged Basra Reed Warbler are described.

Abstract:

Wing lengths of Clamorous Reed Warblers Acrocephalus stentoreus in Israel Wing length measurements taken from first-year, pre- and post-moulting (annual, complete) Clamorous Reed Warblers were recorded at a site in northern Israel. The resulting data set was examined using a time-series of residuals (CUSUM). Results from this analysis can explain the reported heterogeneity found in a comparable data set by Merom et al. (1999). Further observations made in their paper are rebutted: (1) an implied assumption that Reed Warbler (Acrocephalus scirpaceus) spring migration in Israel ends by 1 May is contrary to other publications; (2) the late autumn occurence in N Israel of longer-winged 1st cal. yr. Reed Warblers, unconvincingly explained as either delayed migration by larger individuals or post fledging feather growth, is most likely due to birds from different provenances origins moving at different seasons; (3) growth during adulthood in Reed Warbler is not a new discovery, though presented as such.

Abstract Stêpniewska K., O¿arowska A. 2012. The Eurasian Reed Warbler (Acrocephalus scirpaceus)breeding in Egypt - a new evidence? Ring 34: 45-50. To date, the documented breeding range of the Eurasian Reed Warbler in Egypt is limited to the Nile Delta. In March and September 2001 two females with brood patches were caught in the Wadi El Rayan Protected Area (30°19’E, 29°12’N) in the Western Desert of Egypt. These records, if accepted, might shift the southern border of the breeding range of Reed Warblers in Egypt west of the Nile Delta. The two individuals were the only records of breeding Reed Warblers in Wadi El Rayan, suggesting that the breeding population is small. It is possible that the population has been established recently because artificial lakes were created in Wadi El Rayan in 1973. The studies during the breeding season are essential to determine if such probable breeders demonstrate a new, but permanent breeding population or only ephemeral incidents, as well as to collect the data on the number, breeding biology and biometrical characteristics of such local populations at the southern limit of the world breeding range of the Reed Warbler.

Abstract:

AbstractAs there is geographic and temporal variation in the rate at which reed warblers Acrocephalus scirpaceus are parasitised by the cuckoo Cuculus canorus , phenotypic plasticity of defences against parasitism could be advantageous. Three experiments were conducted using three populations of reed warblers, parasitised by cuckoos to varying degrees, to test if reed warbler defences against parasitism are plastic. In an unparasitised and a rarely parasitised population, attempts to simulate the presence of cuckoos at the nest or in the habitat failed to stimulate an increase in rates of egg rejection. However, three lines of evidence supported the view that both unparasitised and parasitised populations were similarly able to discriminate odd eggs but that there is phenotypic plasticity in the decision to reject those eggs. First, reed warblers at all populations pecked model eggs, thereby indicating recognition of the model egg as a foreign egg, but varied in their tendency to reject them. Second, reed warblers at two populations, one unparasitised and the other frequently parasitised, rejected brown painted reed warbler eggs at the same rate, suggesting that there are no differences between populations in the ability to reject some types of eggs. Finally, rates of rejection decreased seasonally only at the frequently parasitised population. These results suggest that phenotypic plasticity can explain population differences in rates of egg rejection, but do not rule out the possibility that genetic differences also contribute to differences between populations.

Abstract:

Abstract We examined the autumn migration phenology of nine Siberian breeding songbirds: Thick-billed Warbler (Iduna aedon), Black-browed Reed Warbler (Acrocephalus bistrigiceps), Pallas’s Grasshopper Warbler (Locustella certhiola), Lanceolated Warbler (L. lanceolata), Yellow-browed Warbler (Phylloscopus inornatus), Arctic Warbler (Ph. borealis), Dusky Warbler (Ph. fuscatus), Radde’s Warbler (Ph. schwarzi), Two-barred Warbler (Ph. plumbeitarsus) and compared the migration dynamic characteristics with their European occurrence time. The study was carried out within the Amur Bird Project in the Russian Far East along the river Amur at Muraviovka Park between 2011 and 2014. The birds were caught with mistnets and ringed with individually numbered rings. For the characterization of the migration, we used timing, the intervals and the peaks of the migration, the percentage of the recaptures and the average time between the first and the last captures. The timing of migration in the studied species differed in the timing, the intervals (30-67 days) and the migration peaks (14 August - 17 September). Considering the size and location of the distribution area, the timing and annual patterns of European occurrences, it is likely that most individuals of Thick-billed Warbler, Pallas’s Grasshopper Warbler, Dusky Warbler, Radde’s Warbler and Two-barred Warbler get to Europe due to the impact of Siberian cyclones. In case of Yellow- browed Warblers, other factors (reverse migration, weather conditions, dispersal movements) may also play a role. Because of their Scandinavian breeding populations, dispersion movement is the most likely reason for vagrants of Arctic Warbler and Lanceolated Warbler. The distribution of the Black-browed Reed Warbler is limited to the eastern edge of the continent, and therefore this species has no European record to date.

Abstract:

Cognitive abilities play an important role for migratory birds that are briefly visiting a variety of unfamiliar stop-over habitats. Here, we compared cognitive abilities-linked behaviour (escape from an experimental cage) between two long-distant migrants differing in stop-over ecology, Sedge Warbler (Acrocephalus schoenobaenus; not territorial, searching for locally superabundant food) and Reed Warbler (A. scirpaceus; territorial, foraging on a common prey) during the autumn migration. After two minutes of acclimatization in the cage, we remotely opened the cage door and recorded the bird’s reaction. We measured latency that individuals needed to escape from a cage. Sedge warblers were 1.61 times more likely to escape from the cage than Reed Warblers. Sedge warblers generally escaped earlier after the door was opened and were 1.79 times more likely to escape at any given time than Reed Warblers. We interpret the prevalence of non-escaped individuals as a general feature of migratory birds. In contrast to resident species, they are more likely to enter an unfamiliar environment, but they are less explorative. We attributed inter-species differences in escape latency to species-specific autumn stop-over refuelling strategies in the context of specialist-generalist foraging. Our study provides ecological insight into the cognitive abilities-linked behaviour of wild animals.

Abstract:

David Stove's sarcastic dismissal of sociobiology rests on a false dilemma.Cuckoos lay their eggs in reed-warbler nests, and the large gape of cuckoo chicks so readily triggers the feeding reflex of the adult warbler that the warbler chicks go underfed. However, argues Stove, the cuckoos (or the cuckoos' genes) are ‘manipulating’ the warblers, getting them to feed cuckoo chicks, only if the cuckoos (or their genes) consciously intend their behaviour to have this effect: ‘The moon causally influences the tides, but it cannot manipulate them…. [C]ausal influence plus resulting advantage are not enough to constitute manipulation. The causal influence must also be purposeful and intended.’

Abstract:

Abstract The selective pressure exerted by avian brood parasites forces their hosts to evolve specific defense strategies. When subject to brood parasite attack, avian hosts will often emit alarm calls. To date, few studies have examined whether and how host responses to different alarm calls indicative of different enemies vary with the host’s breeding stage. We carried out alarm call playback experiments during both the egg and nestling stages of the oriental reed warbler Acrocephalus orientalis, a host of the common cuckoo Cuculus canorus. The playback exemplars were selected from recorded alarm calls of the warbler to the presence of common cuckoos, sparrowhawks Accipiter nisus, and oriental turtle doves Streptopelia orientalis, which represented brood parasite, predator, and harmless control, respectively. The results showed that the oriental reed warblers did not discriminate alarm calls issued to different intruder types, but the intensity of the response was significantly higher in the nestling stage than in the egg stage. Attack behavior related to sparrowhawk alarm calls was absent in the egg stage, but aggressive behavior increased dramatically and exceeded the attack frequency in response to the cuckoo alarm call in the nestling stage, implying a shift in the tradeoff between the parents’ own survival and the loss of offspring. Alarm calls attracted a larger number of conspecifics than members of other species. In general, the oriental reed warbler had consistently stronger responses to different alarm calls in the nestling stage than in the egg stage, supporting the offspring value hypothesis.

Abstract:

Meadow ecosystems comprise a significant part of the area of Ukraine, especially in its western regions. Those ecosystems are subjects of concern today because of the active agricultural use and droughts that also threatens the animal population of meadows, including birds. Studies of meadow bird species of western Ukraine are limited to atlases, which results in a lack of precise data. This work was part of an international project on the conservation of the great snipe Gallinago media and allowed us to collect valuable data on the abundance and occurrence of meadow bird species nearby to the Polish and Belarusian borders of Ukraine — territories that are commonly ignored by Ukrainian researchers. The surveys of meadow birds conducted near the Ukrainian-Polish border in 2020 have shown that the general state of the marshes is worse compared to 2019: even close to the Western Bug river, only deep oxbow lakes were wet or contained some water, but minor lakes and wetlands of the valley were found to be dry. In total, we observed 141 bird species belonging to 17 orders. Among them, 26 were common by abundance and frequency, such as the great egret Ardea alba, the white stork Ciconia ciconia, the common quail Coturnix coturnix, the corn crake Crex crex, the northern lapwing Vanellus vanellus, the common redshank Tringa totanus, the common cuckoo Cuculus canorus, the Eurasian skylark Alauda arvensis, the meadow pipit Anthus pratensis, the western yellow wagtail Motacilla flava, the sedge warbler Acrocephalus schoenobaenus, the marsh warbler A. palustris, the great reed warbler A. arundinaceus, the common whitethroat Sylvia communis, the whinchat Saxicola rubetra, the thrush nightingale Luscinia luscinia, the common linnet Linaria cannabina, the corn bunting Emberiza calandra, the common reed bunting E. schoeniclus, and 7 more species, which were observed frequently though are not typical marshland species. We have identified the species that can be used as indicators of parameters of marsh ecosystems such as grass height (corn crake, western yellow wagtail, and sedge warbler), moisture (common redshank, common cuckoo, and the sedge and great reed warblers), and habitat type (corn crake, European bee-eater Merops apiaster, sedge warbler, common reed, and corn buntings).

Abstract:

AbstractGlobal environmental processes like climate change could severely affect population level migratory behaviour of long range migrant birds. We analyzed changes in migration phenology and biometrics of three closely-related long-distance migrant Acrocephalus species. We used the records of 12 063 Sedge, 12 913 Reed, and 5 409 Marsh Warblers caught and ringed between 1989–2009, at a Hungarian stopover site. Quantile regressions were used to analyse the changes in spring and autumn migration phenology. Median spring arrival date of Sedge and Reed Warblers shifted 6.5 and 7.5 days earlier, respectively. Autumn arrival of all species shifted one (Reed and Marsh Warblers) or two (Sedge Warbler) weeks later. Mean body mass of adult Reed and Marsh Warblers decreased in spring (by 0.3 and 0.2 grams, respectively) and in autumn (by 0.8 and 0.2 grams, respectively) while body mass of adult Sedge Warblers decreased only in autumn (by 0.4 grams). Mean wing length of all species increased significantly (range of change: 0.6–1 mm). Despite the fact that the studied species are closely related, all three have remarkably different migration strategies. However, similar patterns can be observed in the studied parameters, indicating that global processes may have general effects on these species, albeit through markedly different mechanisms.

Abstract:

Body Condition and Fat Score in Local and Passage Populations of the Great Reed Warbler (Acrocephalus arundinaceus) During the Spring Migration in NE Bulgaria The fat level and the body mass of local Great Reed Warblers in the Kalimok Field Station, NE Bulgaria (41°00'N, 26°26'E) were compared with those of passing birds. During the springs of 1998-2004, 591 individuals of this species were mist-netted and handled according to the guidelines in the Manual of Field Methods (ESF project) and to the South-East European Bird Migration Network (SEEN) standards. As local birds we identified 60 individuals caught at least twice in different seasons. The means of the fat score and the body mass calculated for the local birds and for the passing Great Reed Warblers were similar. Also, the time of the local birds arrival and the passage of the species in the region studied coincided. Therefore, we suggest that the southern and northern populations have equal potentials for realization of their migratory state and birds from southern populations could spread in spring to the north, being an important interregional gene flow in Great Reed Warblers.

Abstract:

AbstractTwo potential defences against brood parasitism by the cuckoo Cuculus canorus were compared experimentally between British populations of reed warblers Acrocephalus scirpaceus that are parasitised at different rates. (1) Rates of rejection of model cuckoo eggs were lower at two unparasitised populations which did not have resident cuckoos, than at a rarely parasitised population which had cuckoos nearby, and at a regularly parasitised population. (2) Reed warblers from an unparasitised population showed a slightly weaker response to taxidermic mounts of cuckoos and, unlike a parasitised population, did not differentiate between mounts of a cuckoo, sparrowhawk Accipiter nisus and jay Garrulus glandarius . Differences in exposure to real predators may explain the differences in responses to mounted predators between populations, as specific aggressive responses to predators are likely to have been learned. Although evidence from dispersal and population turnover data suggests that there is likely to be gene flow between reed warbler populations in Britain, the hypothesis that the population differences reflect genotypic differences could not be ruled out. An alternative explanation of phenotypic plasticity in defences could also explain the population differences. Phenotypic plasticity in defences would be favoured in environments where the risk of parasitism fluctuates, if those defences are costly to unparasitised reed warblers.

Abstract:

Savi’s Warbler Locustella luscinioides has established as a nesting species in a few shallow reed lakes of southern Sweden during the last twenty years. Knowledge of the habitat requirements of a newly established species is important to maintain a viable population and design action plans. We examined the vegetation parameters in occupied territories of Savi’s Warblers at Lake Tåkern, the country’s stronghold for the species. We found association with the outer edge zones and fragmented areas of vegetation dominated by common reed Phragmites australis. Occupied territories differed from randomly chosen unoccupied (control) sites by having a thicker layer of basal litter, and on average more willow bushes (Salix spp.). Reed density and height did not differ between occupied territories and control sites. It is likely that the Tåkern population will continue to increase until it is limited by lack of willows or dense basal litter, the traits important for the establishment of territories. It is also likely that the species will continue to increase in Sweden as long as suitable reed habitats are left unaffected.

Abstract:

Nesting parameters such as clutch size, hatching rate or nesting success have been extensively studied in birds in relation to biotic and abiotic factors. In this study we aimed to investigate the effects of air temperature, amount of precipitation, reed burning, and water depth (independent variables) on nest density, clutch size, hatching rate, and nesting success (dependent variables) of the Great Reed Warbler during a nine-year period. We found that neither the clutch size nor the hatching rate was influenced by any of the predictor variables. Nest density was positively influenced by the water depth, while the nesting success was negatively related to the amount of precipitation. Reed burning had no effect on any of the nesting parameters. Similarly, to our results, short-term studies reported a positive relationship between nest density and water depth, and a negative relationship between the nesting success and amount of precipitation, indicating that these two environmental variables generally influence the two nesting parameters. However, the impact of various reed management practices, such as harvesting or removal, on the nesting variables of the Great Reed Warbler needs further clarification.

Abstract:

SummaryThe Aquatic Warbler Acrocephalus paludicola is a globally threatened habitat specialist that breeds in open fens in Central and Eastern Europe. Because bush and reed encroachment threaten many suitable breeding areas, habitat management is necessary to maintain the open wetlands that Aquatic Warblers require for nesting. The effectiveness of mowing as habitat management has so far only been assessed by counting the number of singing males. To assess whether mowing also affected vital reproduction parameters, we analysed Aquatic Warbler productivity in the Biebrza National Park, Poland, on plots in four different successional stages after mowing. Our study showed that productivity was lowest in the first year after mowing, but increased to the highest levels in the second year after mowing. The productivity differences between areas at different stages after mowing resulted from differences in nest density, since we found little evidence for an effect of mowing on nest survival or the number of fledglings produced per successful nest. Nest survival was highly variable between years and varied mostly with nest age and nest initiation date. The density of singing males was positively correlated with both the nest density and the number of fledglings produced in an area, suggesting that this simple indicator could be used to rank the quality of Aquatic Warbler habitats. We recommend that in mesotrophic fen mires, such as the Biebrza valley, mowing as habitat management is applied less frequently than every second year.

Abstract:

Abstract In this study we conducted a multiple logistic regression analysis of factors hypothesized to influence the risk of Reed Warbler (Acrocephalus scirpaceus) brood parasitism by the Common Cuckoo (Cuculus canorus) on study sites in the south-eastern part of the Czech Republic. We collected data from Common Cuckoo nesting sites surrounding two fishponds. Our logistic regression models were based on the dichotomous dependent variable, parasitism of the Reed Warbler nest, and seven independent variables. Our first model used all data available across sites and years and resulted in a final model in which the only significant contributor was the independent variable “cuckoo view,” the view of host nests from the cuckoo's vantage point in a tree. A second model was developed using data limited to sites and years with the largest sample sizes and expected to yield the most reliable results. That model resulted in three significant contributors: site, cuckoo view, and neighborhood view. In both data sets, the odds of nest parasitism were shown to increase as the view of the host nest became more direct. However, a direct view of the focal nest raised the risk of parasitism to a much greater degree than did a direct view of the neighborhood of nests. Our results provide support for a nest-exposure hypothesis of brood parasitism risk. Although our models have identified nest exposure to be the best predictor of nest parasitism in this system, work remains to unravel the potentially complex relationship among Common Cuckoos, habitat structure, and Reed Warbler hosts.

Abstract:

Abstract Floodplain forest of the Upper Mississippi River provides habitat for an abundant and diverse breeding bird community. However, reed canary grass Phalaris arundinacea invasion is a serious threat to the future condition of this forest. Reed canary grass is a well-known aggressive invader of wetland systems in the northern tier states of the conterminous United States. Aided by altered flow regimes and nutrient inputs from agriculture, reed canary grass has formed dense stands in canopy gaps and forest edges, retarding tree regeneration. We sampled vegetation and breeding birds in Upper Mississippi River floodplain forest edge and interior areas to 1) measure reed canary grass cover and 2) evaluate whether the breeding bird assemblage responded to differences in reed canary grass cover. Reed canary grass was found far into forest interiors, and its cover was similar between interior and edge sites. Bird assemblages differed between areas with more or less reed canary grass cover (>53% cover breakpoint). Common yellowthroat Geothlypis trichas, black-capped chickadee Parus atricapillus, and rose-breasted grosbeak Pheucticus ludovicianus were more common and American redstart Setophaga ruticilla, great crested flycatcher Myiarchus crinitus, and Baltimore oriole Icterus galbula were less common in sites with more reed canary grass cover. Bird diversity and abundance were similar between sites with different reed canary grass cover. A stronger divergence in bird assemblages was associated with ground cover <15%, resulting from prolonged spring flooding. These sites hosted more prothonotary warbler Protonotaria citrea, but they had reduced bird abundance and diversity compared to other sites. Our results indicate that frequently flooded sites may be important for prothonotary warblers and that bird assemblages shift in response to reed canary grass invasion.

ABSTRACT Stêpniewska K., El-Hallah A., Busse P. 2011. Migration dynamics and directional preferencesof passerine migrants in Azraq (E Jordan) in spring 2008. Ring 33, 1-2: 3-25. Azraq ringing station is located in the Azraq Wetland Reserve in the eastern part of Jordan, on the Eastern Palearctic Flyway. It covers different types of habitat: reedbeds and a dry area with tamarisks (Tamarix sp.) and nitre bushes (Nitraria billardierei). In total, from 18 March till 28 April 2008, we caught 2767 birds from 64 species. Three species dominated distinctly, constituting 58% of total number of caught birds: the Reed Warbler (Acrocephalusscirpaceus) - 570, the Chiffchaff (Phylloscopus collybita) - 535 and the Lesser Whitethroat (Sylvia curruca) - 488 birds. The catching dynamics reveals the highest numbers of birds in the beginning of the studied period. The total number constantly decreased till 6 April and then subsequently increased. The first high peak of the dynamics at the end of March was due to intensive migration of Chiffchaffs and Lesser Whitethroats. The second one at the end of April was caused by pronounced migration of Reed Warblers and Blackcaps. High numbers of migrants in the beginning and at the end of the catching period reveal that we did not cover the whole migration season in Azraq, so it is necessary to begin the study much earlier and to finish later there. We performed also 1169 directional preferences tests using Busse’s orientation cage, mostly for the Reed Warbler. Directional preferences of tested birds reveal clear dominance of NW headings - towards European breeding grounds. The NE headings towards Asian breeding grounds were also present. There was a low share of reversed headings, especially SE. We suppose that birds showing NW headings could migrate from wintering grounds in Africa across the most southern coasts of the Arabian Peninsula; these flying to the NE seem to have crossed Egypt and then fly along the Arava Valley. Many species presented in this paper, like the Red-backed Shrike (Lanius collurio), could show loopmigration, flying in spring more eastern than in autumn. High numbers of caught and observed birds, including habitat-specialists like numerous Acrocephalus warblers, reveal that the Azraq Wetland Reserve is a very important place for Palearctic migrants during their migration through desert areas of the Middle-East.

Abstract:

AbstractCutaneous cysts with trematodes of Collyriclum faba have been found in birds during their spring and post-breeding migrations in the Czech Republic. During spring migrations, C. faba was found in one dunnock Prunella modularis, two European robins Erithacus rubecula, three common nightingales Luscinia megarhynchos, one song thrush Turdus philomelos and one great reed warbler Acrocephalus arundinaceus. During post-breeding migration, the same parasite was found in one garden warbler Sylvia borin, one whitehroat S. communis, three goldcrests Regulus regulus and one Eurasian treecreeper Certhia familiaris. The newly identified hosts of C. faba are dunnock, common nightingale, song thrush, great reed warbler and Eurasian treecreeper. Geographical areas of the birds' infection were identified from an analysis of reports on ringed birds of the same species, the time necessary for the development of cutaneous cysts with C. faba and the time of their survival, and hitherto known geographical areas of endemic occurrence of C. faba. It is presumed that birds trapped during spring migrations were infected in some montane and submontane regions in south-western Europe (the Alps, the Apennines). Birds infected during autumn migration or post-breeding vagrancy could have been infected in the Central European Carpathians, the region of C. faba endemic occurrence. For migrating birds, the impact of C. faba infections has not been hitherto assessed.

Abstract:

Abstract Species facing similar selection pressures should recognize heterospecific alarm signals. However, no study has so far examined heterospecific alarm-call recognition in response to parasitism by cuckoos. In this study, we tested whether two sympatric host species of the common cuckoo Cuculus canorus, Oriental reed warbler Acrocephalus orientalis (ORW, main host), and black-browed reed warbler Acrocephalus bistrigiceps (BRW, rare host), could recognize each other’s alarm calls in response to cuckoos. Dummies of common cuckoo (parasite) and Eurasian sparrowhawk Accipiter nisus (predator) were used to induce and record alarm calls of the two warbler species, respectively. In the conspecific alarm-call playback experiments, ORW responded more strongly to cuckoo alarm calls than to sparrowhawk alarm calls, while BRW responded less strongly to cuckoo alarm calls than to sparrowhawk alarm calls. In the heterospecific alarm-call playback experiments, both ORW and BRW responded less strongly to cuckoo alarm calls than sparrowhawk alarm calls. BRW seemed to learn the association between parasite-related alarm calls of the ORW and the cuckoo by observing the process of ORW attacking cuckoos. In contrast, alarm calls of BRW to cuckoos were rarely recorded in most cases. BRW with low parasite pressure still developed recognition of heterospecific parasite-related alarm call. Unintended receivers in the same community should recognize heterospecific alarm calls precisely to extract valuable information.

Abstract:

Abstract In the case of cuckoo parasitism, the maintenance of host specificity may be closely related to active host selection. In the reed wetlands of the Yongnian National Wetland Park, China, four host species of common cuckoos (Cuculus canorus) with similar nest structures breed sympatrically, namely, the Oriental reed warbler (Acrocephalus orientalis) (ORW), vinous-throated parrotbill (Sinosuthora webbiana) (VP), reed parrotbill (Paradoxornis heudei) (RP) and blunt-winged warbler (Acrocephalus concinens) (BW). Cuckoo parasitism rates on ORW (14.5%) and BW (18.2%) were found to be significantly higher than those on two species of parrotbills (RP 1.4% and VP 0%), and cuckoo eggs mimicked the size and coloration of ORW eggs significantly more closely than those of the eggs of the other three hosts. Egg recognition experiments revealed that the ability of ORW and VP to recognize nonmimetic eggs was significantly greater than that of BW and RP. Different life history strategies of the four hosts, including antiparasitic strategy, breeding time period and population density may partly explain the difference of parasitism in this multiple cuckoo-host system. Our study suggests that determining host life history traits and antiparasitic strategies are important for a better understanding of the specificity of host selection in common cuckoos.
