Summary for migrant species:
November is the peak month for migrant raptor diversity and this month matched last year’s record of 18 migrant species, while the numbers – 2666 migrant raptors – more than doubled that of last year’s 1090. The Southern Ridges continued to attract raptor watchers, with Henderson Waves being the favoured spot. On 12 November, a largish accipiter showed up west of Telok Blangah Hill Park, circled a few times and headed back west. Sensing something promising, Tan Gim Cheong snapped a few pics to confirm its identity – a rare Eurasian Sparrowhawk – the 5th record for this species in Singapore. On 20 November, Oliver Tan was well rewarded for his time spent at Henderson Waves with another rare raptor – a Short-toed Snake Eagle.

After last month’s single record at Kent Ridge, we had three records of the rare Greater Spotted Eagle, all juveniles: one on the 3rd flying high over Changi Business Park, photographed by Zacc HD; one on the 4th at Henderson Waves, photographed by See Toh Yew Wai; and another one on the 10th, also at Henderson Waves, photographed by Tan Kok Hui. On the 6th, Low Choon How located a Northern Boobook at Tuas and another was found dead at a condo on the 10th, collected by David Tan. Two juvenile Black Kites were recorded: one on the 3rd at Tuas and another on the 8th at Hindhede Nature Park, both photographed in flight.
There were two flybys of the uncommon Eastern Marsh Harrier at Turut Track, an adult male on the 4th, photographed by Low Choon How; and a juvenile on the 5th, photographed by Francis Yap. On the 11th, while guiding a student group during the bird race, Adrian Silas Tay photographed a rare Pied Harrier, a juvenile, at Sungei Buloh Wetland Reserve.

An uncommon Common Buzzard was photographed at Pasir Ris on the 2nd, and Dr Chaiyan remarked that it was a refectus juvenile. This month’s 11 Grey-faced Buzzards exceeded last month’s six. On the 3rd, five were recorded at Henderson Waves, two at Lorong Halus; on the 6th, two at Henderson Waves; and on the 10th, two at Lazarus Island; all being recorded between 10am to 1pm.
The uncommon Jerdon’s Baza was recorded twice, on the 19th at Preston Road perched on a tree, and on the 23rd flying over Henderson Waves. As Preston Road is near Henderson Waves, it may have been the same individual on both dates. Another uncommon raptor, the Common Kestrel was photographed at Neo Tiew Lane on the 29th.

Fifty nine Chinese Sparrowhawks were recorded, many of them over Henderson Waves, while one adult female seemingly returned to winter at Ang Mo Kio. Eight Peregrine Falcons and five Western Ospreys were also recorded. There was a report of an immature Rufous-bellied Hawk-Eagle (which is often confused with the resident Changeable Hawk-Eagle) rescued on the 4th at Pasir Ris and subsequently released.
Finally, we come to the most abundant migrant raptors. 209 Japanese Sparrowhawks were recorded, many of them at Henderson Waves. From 35 birds last month, we had 664 Black Bazas this month, with a flock of 200 birds on the 8th at Telok Blangah Hill Park. The Oriental Honey Buzzard is tops again with 1698 birds, with a day high of 488 birds, which included a stream of 200 birds at noontime, at Tuas on the 10th.

Highlights for sedentary species:
Both records of the torquatus Oriental Honey Buzzards were of the non-tweeddale form; one perched at Mandai on the 14th, and another in flight at Telok Blangah Hill Park on the 28th.

At Bukit Timah on the 8th, Richard White photographed an immature White-bellied Sea Eagle that had lost all its secondaries and half of its primaries on its right wing, and most of its tail feathers. Amazingly, it could still fly!

Nesting activities were observed for three resident species. A White-bellied Sea Eagle flying with a 2m long stick at West Coast, a Brahminy Kite flying with a smaller stick on the 22nd, a Grey-headed Fish Eagle perched near a nest at Punggol and a pair of Changeable Hawk-Eagles at their nest at Mount Faber. The other resident raptors recorded included the Crested Goshawk and Black-winged Kite.
