1 Singapore Raptor Report Early Autumn Migration, July-September 2017 Peregrine Falcon (ernesti subspecies), at Pulau Ubin, 17 August 2017, by Xu Weiting Summary: The Osprey, Oriental Honey Buzzard, Japanese Sparrowhawk, Chinese Sparrowhawk and Peregrine Falcon were recorded during the July to September period. The Osprey was recorded in small numbers all 3 months, at the Kranji-Mandai and Yishun Dam areas. The 5 Oriental Honey Buzzards recorded from 13 July to 6 September are more likely to have stayed for the summer; and the first autumn arrival was on 24 September at Lorong Halus, followed by another on 25 September at Bidadari and small flocks on 30 September at Tuas. A torquatus Oriental Honey Buzzard tweeddale morph was photographed at Toa Payoh on 30 September. The first arrival of the Japanese Sparrowhawk was on 24 September at Lorong Halus (3 birds), followed by singles at Bidadari and Jelutong Tower before the month ended. The first arrival of the Chinese Sparrowhawk was also on 24 September at Lorong Halus (2 birds), followed by an individual at Jelutong Tower later on. A Peregrine Falcon (ernesti subspecies) was recorded at Pulau Ubin on 17 August; another reported from the 39th floor of OCBC Building on 24 August was also seen feeding on feral pigeons on previous occasions.

2 For the resident raptors, highlights included the locally rare Crested Serpent Eagle on 13 July at South Buona Vista Road. On 18 August at Little Guilin, a juvenile Grey-headed Fish Eagle was observed whining constantly in the presence of an adult, but just 2 weeks later, on 1 September, the adults were seen building a new nest on a tall tree. A juvenile Crested Goshawk was recorded at Pasir Ris Park on 13 July, and Changi Village on 10 September, with a shrew in its talons; adults were recorded on 17 August at Kent Ridge Park, 21 August at Aljunied (2 birds), and 7 September at Sentosa, with a Plantain Squirrel in its talons. The Black-winged Kite was recorded on 9 July at Kranji Marsh, 10 July at Punggol Barat (2 birds) and 20 August at Changi Point Ferry Terminal. A Changeable Hawk-eagle which probably fledged sometime in June or earlier was seen on the nest at Dairy Farm area on 1 July and 15 July, maybe it was 'homesick'.
