Academic literature on the topic 'Brahminy Kite'

Brahminy kite (Haliastur indus) is one of bird of prey species that occupy position as top predator. Many brahminy kite was captured and was kept as pet which caused those birds lose their ability to hunt as a result of being caged for too long and for not to be trained to hunt. In Bali Wildlife Rescue Centre, the confiscated brahminy kite showed begging behavior in which the birds “whine” every time a human approach. This kind of behaviour affect their readiness to be released in the wild. The purpose of this study was to determine the daily activity and the frequency of begging behaviour of confiscated brahminy kite in Bali Wildlife Rescue Centre. This study was conducted in January 2020. This study found that the brahminy kite at the Bali Wildlife Rescue Centre spent the most of their time for perching. The second highest activity was preening, whereas the least activities were feeding and moving. The highest percentage to beg in brahminy kite was recorded in the morning, whereas the lowest percentage was in the midday. The results of this study indicate that the confiscated brahminy kite at the Bali Wildlife Rescue Centre still needs more time to be rehabilitated prior released ack into the wild.

ABSTRACT Brahminy Kite (Haliastur indus) is included in protected wild species list. Concervation is an alternative way to save this species from being extinct. The objective of this research was to find out the comparison of daily behaviour between male and female Brahminy Kite at Ragunan Zoo- Jakarta such as three activities. These behaviours were motionless, movement and ingestive. The descriptive method was used in this study, by direct observation to the behaviour of individual bird. The focal animal sampling was used as a method for recording behaviour, which means observing one individual for a specified amount of frequence and recording all instance of its behaviour. The observation was carried out on 2 birds with sex male and female. Each individual’s bird was observed each day from 06.00 to 18.00. Data analysis used descriptive analysis and nonparametric statistics analysis with U Mann-Whitney Test. The result of this analysis indicated if there were comparison of motionless behaviour and movement behaviour between male and female Brahminy Kite, where testing criteria Eject H , density is 0.00 < α, level was significance but there was not comparison of ingestive behaviour between male and female Brahminy Kite. Density is 0.38 > α,level was insignificant Keyword : the comparison, daily behaviour, Brahminy Kite, Ragunan zoo

The breeding ecology and diet of the Brahminy Kite Haliastur indus was studied in urban Darwin, Northern Territory, in 2015 (n = 10 territories) and 2016 (n = 13 territories). Laying was estimated to have occurred from c. 15 June to 3 October, with juveniles fledging during August to December. African Mahogany Khaya senegalensis was the most common nest-tree (12 of 14 nest-trees). A breeding success rate of 17 from 21 active nests (81%) was recorded across the two breeding seasons. Nest dispersion was 25 nests/100 km2 in 2015, and 31.3 nests/100 km2 in 2016. A total of 394 prey items was recorded, comprising 243 reptiles (61.7%), 34 birds (8.6%), 34 crustaceans(8.6%), 27 fish (6.9%), 22 amphibians (5.6%), 19 mammals (4.8%) and 15 insects (3.8%). The Northern Water Dragon Lophognathus temporaliswas the most common prey item, being recorded on 233 occasions.

Migratory birds are birds that fly or move from their breeding place to their non-breeding location. Migratory birds usually migrate to the southern part of the earth or tropical regions to avoid limited resources during winter in their breeding areas (Bildstein, 2006). Bird of Prey or Raptors are a group of birds that frequently migrate. Raptors carry out-migration in several areas which are commonly referred to as flyways. Indonesia is also part of the flight path for migratory birds (Sukmantoro et al., 2007). At this time there were approximately 17 types of migrant raptors in Indonesia. Research on raptor migration has been carried out for a long time in various regions. In the Yogyakarta area, there have been observations of a migrant raptor, but there are no official publications and research on migrant raptor in the Bukit 76 Kaliurang area, Yogyakarta. Therefore this research was conducted to know about migratory raptor in Yogyakarta. This research was conducted at Bukit 76 Kaliurang, Hargobinangun, Pakem, Yogyakarta. The research was conducted in December 2019-March 2020, July-August 2020, and October-November 2020. This research was conductes through observations in the morning at 07.00-11.00 WIB using birdwatching techniques and purposive methods. The results of this study recorded 1 species of migrant raptor, namely the Oriental Honey-buzzard (Pernis ptilorhynchus) and 2 species of resident raptors, namely the Crested Serpent Eagle (Spilornis cheela) and the Brahminy Kite (Haliastur indus).

The conversion of natural environments into land useful for human habitation has many effects on biodiversity and can alter the way terrestrial and aquatic ecosystems function. Urbanisation is particularly potent in coastal areas, where birds of prey have often been recognised as indicators of environmental health. In Australia, four coastal raptor species are present: White-bellied Sea-Eagle (Haliaeetus leucogaster), Eastern Osprey (Pandion haliaetus cristatus), Brahminy Kite (Haliastur indus) and Whistling Kite (Haliastur sphenurus). Coastal raptors are important vectors of nutrient transport between marine and terrestrial systems and are key players in structuring biological communities. Most coastal raptor research has been in southern Australia where populations are in decline. However, little has been conducted in the urbanising region of South-East Queensland (SEQ). This thesis addressed urbanisation impacts on Australia’s coastal raptors in SEQ including breeding habits, physical impacts, rehabilitation outcomes and the importance of protected areas. Chapter 2 discussed Eastern Ospreys and their ability to adapt to urban areas and nest on artificial structures. This behaviour was investigated in two regions of SEQ: urbanised Moreton Bay Marine Park (MBMP) and rural Great Sandy Marine Park (GSMP). Most nests in MBMP were on artificial structures, while in GSMP most were on natural structures. This chapter showed that Eastern Ospreys have a high propensity for nesting on artificial structures when close to urban environments and that additional nesting platforms should be erected to avoid the risks associated with nesting on unsafe structures. Physical threats in urban landscapes are many and varied for Australia’s coastal raptors. These threats were investigated in Chapter 3, where admissions to Currumbin Wildlife Hospital Foundation (CWH) were analysed. Most birds were admitted from anthropogenic causes, most significantly from fishing equipment entanglement. Bird attack and vehicle strike were also significant. This is the first time fishing equipment entanglement has been quantified as a significant cause of injury to coastal raptors. This chapter highlights the importance of public education on the threats fishing equipment can cause to local wildlife. Although the majority of coastal raptors admitted to CWH were released, assessing rehabilitation success of raptors has been rarely attempted. Rehabilitation is intensive, expensive and the success rates post-release are rarely investigated. In Chapter 4, 28 banded coastal raptors and 2 White-bellied Sea-Eagles, fitted with GPS tracking devices, were monitored post-release. Band return was low but both tagged White-bellied Sea-Eagles survived beyond the crucial six week period, suggesting successful rehabilitation. Home ranges were much larger than previously reported for this species and illustrates how GPS tracking can enhance our knowledge of the ecology of these raptors. Chapter 5 explored trends in the presence of these species in SEQ using three datasets. Long-term data from Queensland Wader Study Group, habitat loss data from Global Forest Watch and nest location data were used to explore temporal trends in species sightings and cumulative habitat loss in Moreton Bay. White-bellied Sea-Eagle and Whistling Kite sightings decreased with increased cumulative tree cover loss while nest location data showed that coastal raptors were nesting in protected areas. These findings suggests that these areas are critical for their persistence in the region. This thesis showed that while many processes threaten the coastal raptors of SEQ, management is possible with education and innovative measures. Watercourses and protected areas were critically important for coastal raptors in urban areas, where fishing equipment entanglement is a key threat. Rehabilitation of coastal raptors by CWH is often successful and could be critical for the management of species populations and mitigation of threats. Furthermore, the benefits of GPS tracking in increasing our knowledge of the ecology of coastal raptors was clearly demonstrated. Although susceptible to many threats, the coastal raptors of SEQ showed resilience and adaptability, finding opportunities to breed in the protected areas of Moreton Bay. Eastern Ospreys have the ability to nest on various structures within the urban landscape and although risky, this behaviour shows that breeding platforms could be erected in urban areas to encourage ospreys to avoid dangerous nest sites and reduce competitive pressures for nesting space with the other species. The information presented in this thesis will contribute significantly to our knowledge on Eastern Ospreys, White-bellied Sea-Eagles, Whistling Kites and Brahminy Kites in coastal South-East Queensland.
