Working from that as a template assuming the Little Guilin pair nested as late as the one Tan Chuan Ming recorded 2012 the feeding goes on for just over 3 months or 14 weeks. So the next time you visit Singapore on a birding trip, take some time to explore the country as well! It is located near the south-eastern tip of the Tonlé Sap, one of three wildlife sanctuaries around the lake, including Boeng Tonlé Chhmar and Prek Toal. However, they also eat other prey, such as reptiles. Many thanks to everyone who had reported their sightings in one way or another, and also thanks  to Danny Khoo, Yeak Hwee Lee, and Michael Kwee for the use of their photos. http://www.globalraptors.org on 11 Dec. 2011 However, just as with the aforementioned species, this bird appears to have adapted to urban water bodies in Singapore, and the ample supply of large non-native fish introduced by irresponsible pet owners inhabiting them. Smaller Lesser Fish-Eagle has a less contrasting tail pattern and typically a more jagged-edged white belly patch in adults; juveniles average paler below overall. Nicoll, D.P. The species was described in 1935 by Ernst Mayr who noticed that earlier observers had overlooked it, thinking it was a juvenile of the white-bellied sea eagle. The Accipitridae have a cosmopolitan distribution, being found on all the world's continents and a number of oceanic island groups. 2012 revisions) (v.1) It is about 63 cm (25 in) long and has a pale brown head, dark brown body and white tail.

The grey headed fish eagle spends much of its time perching upright on bare branches over water bodies, occasionally flying down to catch fish. They feed on a range of prey items from insects to medium-sized mammals, with a number feeding on carrion and a few feeding on fruit.

IOC World Bird Names, version 3.2 (v.1) Although materiel is limited it can tentatively be said that in Singapore GHFE commence nesting any time from September to January. [4] Nests have been found in January–March in Burma, April in Sumatra and August in Borneo, it is unclear whether these nest were old or being used for breeding. [3] Juveniles are paler with darker streaking. Like many raptors, the female is slightly larger than the male, and can measure up to 90 cm (35 in) long with a wingspan of up to 2.2 m (7.2 ft), and weigh 4.5 kg (9.9 lb).

February might just be the peak breeding period for the Crested Goshawk, as breeding-related activities were observed at five different locations: on the 5th, a nest with one chick was recorded at West Coast Park; on the 10th, courtship feeding was observed between a pair which had built a nest at Pasir Ris Park; the goshawk at Ang Mo Kio on the 10th was apparently nesting for the second season; at Pasir Panjang, an active nest with two chicks was observed throughout the month; and at Thomson, a nest with two chicks was recorded during the month, although only one chick survived. Its feathered tarsus marks this species as a member of the subfamily Aquilinae. [4] [11], Grey-headed fish eagles live in lowland forest up to 1,500 m above sea-level. Nine Grey-headed Fish Eagles were recorded at various waterbodies, including an adult at Pandan River on the 18th, ‘captured’ on camera by a lucky few (Yeak Hwee Lee, et al) in the act of catching an adult male Cinnamon Bittern that was hunting in the river. Whether this is the primary prey item of their diet or a seasonal occurrence in this are remains unclear. Another option is when there are eaglets in the nest. It takes a lot of down force to lift off judging from the turbulence on the water surface, captured in this photo by Steven Wong. Reversing its flight after the catch had to be another feat of power, using its wings to stop it going deeper and then pushing it back up to the surface. [2] https://www.hbw.com/species/grey-headed-fish-eagle-icthyophaga-ichthyaetus. The Grey-headed Fish Eagle (Ichthyophaga ichthyaetus) is near-threatened due to habitat degradation, pollution and over-fishing [1]. Proposed conservation actions include conducting surveys to determine important areas for the birds, regular monitoring at sites across the eagles' range, [10] A number of other conservation actions have also been proposed by the IUCN, these include surveys to reveal important areas and regularly monitor at various sites throughout its range, protect forest in areas known to be important to the species and conduct awareness campaigns involving local residents to engender pride in the species and encourage better care of wetland areas. [3] [4] These begin as subdued low short notes each succeeding one more strongly upturned and more strident then previous then dying away again and are uttered from a perch or on the wing. They were first videoed by Jeremiah Loei on 10th. [3] It is rare and local in South Thailand and rare in Laos; [4] scarce in Vietnam, Cambodia and Malaysia to Sumatra; [8] [9] [10] very rare in Java and Sulawesi except for a small local population and scarce in Borneo and the Philippines. [9] [10] noted that these statements are based mostly on anecdotal evidence, although their studies found a definitive negative link between human habitation and grey-headed fish eagle nest occupancy rates in Cambodia.

I did several digital bird paintings in the past years using the Note 10. [4] The nest is lined with green leaves and were situated in tall trees (8–30 m) on or near the top of the tree with an open crown structure, which can be in a forest or a standalone tree.

IOC World Bird Names, version 2.11 (v.1) The grey headed fish eagle spends much of its time perching upright on bare branches over water bodies, occasionally flying down to catch fish.

When hunting fish, they hunt from a perch and snatch their prey from the surface of the water, something for which their curved talons are Clements 6th edition (incl.
