Summary:

The early migrants included all the five expected species, namely the Western Osprey, Oriental Honey Buzzard, Chinese Sparrowhawk, Japanese Sparrowhawk, and Peregrine Falcon, during the July to September period.

A total of 46 Oriental Honey Buzzards were recorded. There were at least seven immature orientalis in July, four in August, and three in September – these are individuals hatched last year, over-summering here this year and are expected to migrate to the north only next spring. At least two torquatus were recorded – one photographed at Springleaf on 20 July by Alex Fok, and a tweeddale morph photographed at Upper Seletar Reservoir on 10 September by Deborah Friets.

The first Japanese Sparrowhawk was recorded on 13 September at Jalan Bahar, and on 26 September, Adrian Silas Tay recorded 28 at The Pinnacles Duxton, including a flock of 12. Aother eight were recorded at Henderson Waves on 28 September. All in, 47 early arriving Japanese Sparrowhawks were recorded.

The first three Chinese Sparrowhawks were recorded on 22 September at Tuas. They were followed by two on 27 September at Jelutong Tower, 3 on 28 September at Henderson Waves, and 8 on 29 September at Tuas.

Four Western Ospreys were recorded, with one at Sungei Buloh Wetland Reserve (SBWR) on 11 July having caught a big fish. The others were singles at the Botanic Gardens on 7 July, Seletar Dam on 14 September, and Marina Bay on 26 September.

Four Peregrine Falcons were recorded – an adult ernesti on 6 Jul at Telok Blangah; a juvenile of indeterminate race on 27 July at Pulau Ubin; a far individual at Marina Bay on 3 August, possibly an ernesti; and another at Kranji Marsh on 29 Sep.

For the resident raptors, seven diurnal species were recorded. Apart from the usual ones, there were records of the rare Crested Serpent Eagle at Pulau Ubin on 2 July & 8 September, and at Malcolm Road on 6 July & 6 September. Notably for nocturnal raptors, a recently fledged juvenile Spotted Wood Owl at Pasir Ris Park fell to the ground on 11 July, but managed to climb back up the tree to reunite with its parents.
