Singapore Raptor Report October 2017 Japanese Sparrowhawk, juvenile, at Jelutong Tower on 25 Oct 2017, by Francis Yap. Interestingly, this individual has dark and pale tailbands that appear equal in width, the most commonly held criteria for Besra. However, other features such as short tail, long primary projection, weak mesial stripe and weak chest markings point to Japanese Sparrowhawk. A good reminder that identification cannot be based on a single feature alone. Summary for migrant species: October 2017 is probably the least remarkable October on record, with only 6 migrant species recorded (we usually record around 9 species in October). For the second year in a row, there were no records of the Black Baza in October, not that they no longer come to Singapore, just that they arrive only later in the year. The bulk of the 70 migrants recorded were made up by the 33 Oriental Honey Buzzards, and 25 Japanese Sparrowhawks. There were 8 Chinese Sparrowhawks, including one female spotted regularly at Ang Mo Kio. Two Western Ospreys were recorded at the Kranji- Sungei Buloh area and one adult Peregrine Falcon was recorded at Kent Ridge on the 3rd. The single juvenile Eastern Marsh Harrier at Mount Faber on the 3rd was a notable record. Page 1 of 9 A pair of Crested Goshawks mating, at Ang Mo Kio on 27 Oct 2017, by Seah Han Wah. Note the small dark droplet-shaped markings on a rather clean white breast of the female (below) versus the bigger rufous-brown patches on the breast of the male (above). Highlights for sedentary species: The locally rare Crested Serpent Eagle was recorded twice at Kent Ridge this month, on the third and the 12th. As for the uncommon Crested Goshawk, a pair was observed mating at Ang Mo Kio; another 4 adults were recorded at Kent Ridge and the Botanic Gardens; and a juvenile at Bidadari, honing its skills at hunting, using a Variable Squirrel as target. Amazingly, all the four records of the torquatus Oriental Honey Buzzards were of the tweeddale form, with at least one female and one juvenile - one at Toa Payoh on 3rd, a female at Jelutong Tower on 7th, a juvenile at Jelutong Tower on 22nd, and a female at Old Upper Thomson on 29th. The other resident raptors recorded included the Grey-headed Fish Eagle, Black-winged Kite, Brahminy Kite and White-bellied Sea Eagle.
