Highlights for sedentary species:

Breeding-related activities were noted for several species. A Changeable Hawk-Eagle was standing on a nest in the vicinity of Dairy Farm Nature Park on the 6th. The Black-winged Kite pair at Seletar was building their nest on the 12th, 20th and 27th, and were harassed by crows. The pair of Brahminy Kites at was perched near their nest on the 25th. A White-bellied Sea Eagle at Jalan Asas was flying about with nesting materials on the 2nd. The Crested Goshawk pair at Pasir Ris was nestbuilding on the 27th, and mated on the 30th, and had to chase away the neighbourhood Oriental Pied Hornbills when these came close to their nest. And for the Buffy Fish Owl, a pair mated on the 2nd and another pair at SBWR had a chick on nest on the 20th.

At Ulu Pandan park connector on the 13th, the resident Grey-headed Fish Eagle was seen attacking a Purple Heron that was fishing in the eagle’s territory. At SBWR Eagle Point on the 15th, two White-bellied Sea Eagles were tussling in the air over a fish, with one eagle upside down mid-air. The Crested Serpent Eagle was recorded at Goldhill Avenue, Pasir Ris and Ubin. The Changeable Hawk-Eagles reminded us of their presence by putting up a good show, allowing for good photos of the dark morph, pale morph and juvenile pale morph.

An adult ernesti Peregrine Falcon was present at Jurong West on the 2nd and 4th. Five torquatus Oriental Honey Buzzards were recorded – at the Botanic Gardens, a male on the 6th, and a female on the 7th; another male flew by Jelutong Tower on the 7th and Neo Tiew Harvest Lane on the 13th; yet a different male at Pasir Ris on the 22nd; and an immature at Springleaf on the 26th.
