Japanese Sparrowhawk, male, at Pasir Ris Park, 25 June 2017, a new and amazingly late date for the species, by Kozi Ichiyama.

Summary:

Four migrant raptor species were recorded in the April to June period. They were the Osprey, Oriental Honey-buzzard, Japanese Sparrowhawk and Peregrine Falcon, all of which were also recorded during last year’s late spring migration.

The most amazing record must have been the Japanese Sparrowhawk photographed on 25th June at Pasir Ris Park by Kozi Ichiyama. This is a full month beyond the extreme date (25 May) in An Annotated Checklist of the Birds of Singapore and well beyond that in The Avifauna of Singapore (1 May). Elsewhere, singles of the Japanese Sparrowhawk were recorded at Bukit Timah and Kranji up to mid April, followed by 2 birds –  a male and a female – flying north at Punggol Barat on 16th April.

Of the 18 Oriental Honey Buzzards recorded, 1 was of the torquatus race and at least 12 were of the orientalis race. Of the orientalis race, 10 were juveniles or second calendar year birds – 4 of these young birds were recorded in April, 2 in May and 4 in June. There were also 2 adult orientalis in April. On 25 April, a young OHB was chased away from the tree where it had perched by a resident Grey-headed Fish Eagle. A single torquatus was recorded from April to June at the Bishan-Ang Mo Kio area.

A single Osprey was recorded at the Kranji-Sungei Buloh area from April to June, and another at Seletar in May. Two Peregrine Falcons were recorded, one at Church Street (migratory race) in April and another at Hindhede in May.

Sedentary Raptors

A Crested Serpent Eagle on 2nd April at Pulau Ubin was the only record of this rare raptor during this 3-month period. For the Grey-headed Fish Eagle, there were 3 at the Kranji-Sungei Buloh area, 2 at the Botanic Gardens, 2 at the Ubin-Changi area, 1 at Bukit Timah area and 1 at Jurong Lake. Small numbers (up to 3 together) of the Black-winged Kite were record at the Kranji-Sungei Buloh area and at the Punggol-Seletar area in all 3 months.

Two nestings of the White-bellied Sea Eagle were observed during this period, one at Pasir Ris (2 chicks) and another at West Coast Park (at least 1 chick). Elsewhere, this common raptor was observed in many areas, with up to 6 birds at any one time. For the Crested Goshawk, there was another successful nesting, with 2 chicks, at the Singapore Botanic Gardens during this 3-month period. Elsewhere, apart from 3 birds calling at West Coast Park on 1st June, all other records were mostly of single birds.

The common Brahminy Kite was recorded in all 3 months and a max of 18 was recorded at Kranji Marsh in April. For the uncommon Changeable Hawk Eagle, records were mostly singles, mainly from the Central Forest areas, Kranji-Sungei Buloh and Simpang Kiri-Punggol stretch. 

addendum to March Raptor Report
2 adults and 1 juvenile Grey-headed Fish Eagle, which was being fed, at Little Guilin was recorded on 27 March 2017 by Keita Sin.
