Singapore Raptor Report March 2017 Oriental Honey Buzzard, pale morph (left) at Alexandra Road on 9 Mar 2017 & dark morph (right) on at the Botanic Gardens on 18 Mar 2017, both by Laurence Eu. Summary for migrant species: In March, 176 raptors of 8 migrant species were recorded. The Black Baza was the most numerous with 70 birds, of which 39 were recorded at the Kranji Marshes on the 4th and another 20 at the National University of Singapore (NUS) on the 20th. The Oriental Honey Buzzard, with 54 birds, was the next in line and 11 were recorded at the NUS on the 21st, all heading north. Of the 32 Japanese Sparrowhawks recorded, 11 were seen at the NUS on the 22nd. Ten Chinese Sparrowhawks were recorded this month, good numbers for this uncommon migrant. Apart from one bird at Jelutong Tower, the other nine were all recorded at the NUS. Four Ospreys were recorded, at the Seletar Dam and Sungei Buloh - Kranji Marshes areas. On the 9th, one Osprey at Sungei Buloh had its catch stolen by a White-bellied Sea Eagle. Four Peregrine Falcons were recorded; none of the resident race. A Grey-faced Buzzard at Kranji Marshes on the 19th was a very good record for this rather uncommon migrant. Lastly, an Oriental Scops Owl, unfortunately, flew into a glass panel at the NUS on the 9th.

At the Botanic Gardens, the Crested Goshawk pair was seen mating on the 7th and reinforcing their nest with sticks, around one month after their first brood of chicks had fledged. Over at Punggol, the Black-winged Kites were seen mating on the 18th, also about a month after their chick had fledged. As for the Grey-headed Fish Eagle, there were records from Kranji Marshes (4th & 5th), Sungei Serangoon (5th) and Seletar (19th) but none from Little Guilin, where it was reported on the 7th that the nest tree had fallen. A rare Crested Serpent Eagle was recorded at Pulau Ubin on the 12th. At Sungei Buloh Wetland Reserve on the 17th, a juvenile pale morph Changeable Hawk-Eagle was seen raiding the nest of a Striated Heron and flying off with a chick in its talons. A loose flock of 17 Brahminy Kites was reported at Kranji Marshes on the 5th. Lastly, a torquatus tweeddale morph Oriental Honey Buzzard was recorded at Pasir Ris Park on the 2nd and another juvenile torquatus tweeddale moph at Jelutong Tower on the 26th.
