Abstract:
Black-billed (Coccyzus erythropthalmus) and Yellow-billed (C. americanus) cuckoos are facultative brood parasites that occasionally lay their eggs in the nests of 10 and 11 other bird species, respectively. This study demonstrates that both cuckoo species produce blue–green eggs that fully or nearly match the eggs of over 70% of their reported host species, a proportion significantly greater than if hosts were being selected at random from the potential host pool. These results suggest that the cuckoos may be selecting hosts on the basis of their egg colour, and support a hypothesis of egg mim

Abstract:
Interspecific brood or nest parasitism is a relatively common breeding behavior in birds. Through this reproductive tactic, brood-parasites avoid the costs associated with raising and maintaining chicks by laying their eggs in the nests of the host species in which they are specialized. The common cuckoo (Cuculus canorus) follows this brood parasite strategy. Female cuckoos lay their eggs in the nests of other bird species, mimicking egg shape, size, and color of the host species. In this paper we report the first documented case of parasitism of tawny pipit nests by the common cuckoo in Spani

Abstract:
Phenological responses to climate change vary among taxa and across trophic levels. This can lead to a mismatch between the life cycles of ecologically interrelated populations (e.g. predators and prey), with negative consequences for population dynamics of some of the interacting species. Here we provide, to our knowledge, the first evidence that climate change might disrupt the association between the life cycles of the common cuckoo ( Cuculus canorus ), a migratory brood parasitic bird, and its hosts. We investigated changes in timing of spring arrival of the cuckoo and its hosts throughout

Abstract:
Abstract The different ways birds searched for food in an Australian Eucalyptus forest led them to detect and capture different kinds of prey. Five major searching modes were identified among 23 common, mostly insectivorous bird species. These were distinguished largely by the rates, distances, and angles moved by birds while foraging and by their prey-capture behavior. Some bird species typically moved slowly, visually examining substrates at relatively long distances, and then took flight to capture prey (e.g. whistlers, flycatchers, muscicapid robins, cuckoos). Others moved at more rapid ra

Abstract:
Hosts of brood-parasitic birds must distinguish their own eggs from parasitic mimics, or pay the cost of mistakenly raising a foreign chick. Egg discrimination is easier when different host females of the same species each lay visually distinctive eggs (egg ‘signatures’), which helps to foil mimicry by parasites. Here, we ask whether brood parasitism is associated with lower levels of correlation between different egg traits in hosts, making individual host signatures more distinctive and informative. We used entropy as an index of the potential information content encoded by nine aspects of c

Abstract:
AbstractA population of cooperatively breeding, group-living splendid wrens was tested with a mounted parasitic cuckoo. At all nests with incubated eggs or nestlings, wrens attacked the cuckoo. The timing and intensity of attacks was independent of the nest day and of the age and breeding experience of the wrens. The breeding female usually spotted and attacked the cuckoo first. Her mate and the nonbreeding helpers responded to her call and mobbed and attacked the cuckoo. Response was no quicker in groups with nonbreeding auxiliaries than in single pairs.

Abstract:
Many bird species can reject foreign eggs from their nests. This behaviour is thought to have evolved in response to brood parasites, birds that lay their eggs in the nest of other species. However, not all hosts of brood parasites evict parasitic eggs. In this study, we collate data from egg rejection experiments on 198 species, and perform comparative analyses to understand the conditions under which egg rejection evolves. We found evidence, we believe for the first time in a large-scale comparative analysis, that (i) non-current host species have rejection rates as high as current hosts, (i

Abstract:
The offspring of brood parasitic birds benefit from hatching earlier than host young. A proposed but little-known strategy to achieve this is ‘internal incubation’, by retaining the egg in the oviduct for an additional 24 h. To test this, we quantified the stage of embryo development at laying in four brood parasitic birds (European cuckoo, Cuculus canorus ; African cuckoo, Cuculus gularis ; greater honeyguide, Indicator indicator ; and the cuckoo finch, Anomalospiza imberbis ). For the two cuckoos and the honeyguide, all of which lay at 48 h intervals, embryos were at a relatively advanced st

Abstract:
Brood parasitic cuckoos lay their eggs in other birds' nests, whereafter the young cuckoo hatches, ejects its nest-mates and monopolizes the care of the host parents. Theory predicts that hosts should not evolve to recognize and reject cuckoo chicks via imprinting because of the risk of mistakenly imprinting on a cuckoo chick in their first brood and thereafter always rejecting their own chicks. However, recent studies have revealed that some hosts do reject cuckoo chicks from the nest, indicating that these hosts’ recognition systems either do not rely on first brood imprinting, or use cues t
