Summary for migrant species:

October 2018 is probably the most remarkable October on record, with 11 migrant species recorded. This is in stark contrast to last October when only 6 migrant species were recorded (we usually record around 9 species in October). A big thank you to the burgeoning number of raptor watchers, especially at Henderson Waves.

453  migrant raptors were recorded, many times the 70 recorded last year. The most numerous were the 219 Oriental Honey Buzzards, followed by 123 Japanese Sparrowhawks, and 57 Chinese Sparrowhawks. In addition, more than 100 unidentified Accipiters were spotted this month and these were likely to have been either Chinese or Japanese Sparrowhawks. The first of the 35 Black Bazas appeared on 22 Oct, more than a week earlier than last year.

Birders at Henderson Waves were rewarded with three sought-after species. The first was the appearance of two Grey-faced Buzzards on 21 Oct, followed by a juvenile Eastern Marsh Harrier on the same morning. Another four Grey-faced Buzzards were spotted over Henderson Waves days later: two on 26 Oct and two on 27 Oct, around mid-day on both dates. In addition, birders on 27 Oct also spotted a Common Buzzard Buteo buteo before noon (note: the various subspecies are ‘lumped’ as Buteo buteo in the NSS bird checklist).

Later the same day, 27 Oct, around noontime, a rare Greater Spotted Eagle made an appearance at Kent Ridge Park, delighting Alan OwYong. Before the month ended, Fadzrun Adnan photographed an immature Rufous-bellied Eagle, another rare visitor, at Pang Sua park connector on 30 Oct, flying about in the company of an Oriental Honey Buzzard.

Two Western Ospreys were recorded, one at the Kranji-Sungei Buloh area and one at Henderson Waves. Six migrant Peregrine Falcons were recorded.

Highlights for sedentary species:

October was a good month for the locally rare Crested Serpent Eagle, with records from four different areas, from Nanyang Technological University (west) on 8th, Pulau Tekong (offshore) on 8th, Jelutong Tower (centre) on 24th and the Southern Ridges (south) on 16th, 21st & 30th.

On 6 Oct, a pair of Crested Goshawks were observed mating at West Coast Park. Then on 23 Oct, 2 chicks of the White-bellied Sea Eagle were seen on a nest at Woodlands. These  are good signs for our resident raptors.

On 6 Oct, at Pulau Ubin near the main jetty, a juvenile Peregrine Falcon of the resident ernesti subspecies was photographed. This form bears some resemblance to, and may be mistaken for, the Oriental Hobby. The other resident raptors recorded included the Grey-headed Fish Eagle, Black-winged Kite, Brahminy Kite and Changeable Hawk-Eagle.

Singapore Raptor Report, Early Autumn Migration, July-September 2018

Summary:

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

A total of 27 Oriental Honey Buzzards were recorded. At least nine were immature orientalis, which would be individuals hatched last year, spending the summer here this year and migrating to the north only next spring. One torquatus tweeddale morph was photographed at Mandai Road on 10 July, and another at Pasir Ris Park on 24 & 25 August, both being adult males.

Twenty nine Japanese Sparrowhawks were recorded, a much higher number compared with the same period last year when only five were recorded. The first  arrival was on 1 September at Kranji Marsh; seven around the central forests from mid-to-end September; one at Pulau Ubin and 20 at the southern ridges, notably 8 on 27 September and 11 on 29 September at Henderson Waves.

The three Chinese Sparrowhawks recorded were all juveniles. The first arrival was a single bird on 24 September at Henderson Waves, followed by another on 29 September and the last one at Pulau Ubin on 30 September.

One Western Osprey was recorded at Yishun Dam on 18 August and another at Sungei Buloh Wetland Reserve (SBWR) on 24 Sep. At Lower Pierce after sunset on 24 September, a sparrowhawk, not identified to species, was going after bats.

Five Peregrine Falcons were recorded, however only the individual on 24 September at  SBWR is likely to be a migrant, with the rest being of the resident ernesti subspecies. The individuals recorded at Hindhede park on 28 July, and Pulau Ubin near the jetty on 19 & 22 August, both perched on telecom towers, were noted as ernesti. The other two recorded on 21 July at Gardens by the Bay, and 25 July at Changi Coastal Road were probably ernesti as well.

For the resident raptors, seven species were recorded, and only the notable records are highlighted. A young White-bellied Sea Eagle was observed sitting on a nest at Loyang on 9 July. A Brahminy Kite was mobbed by crows at Lorong Halus on 28 August. For the Crested Goshawk, two juveniles recorded during this period are good signs of breeding, one at Windsor Nature Park on 7 July and another at Bidadari on 28 September.

Two Crested Serpent Eagles were recorded. One individual photographed by Benny Ng at Yusof Ishak Secondary School on 18 August was notably a juvenile, which is rarely seen in Singapore. The other was an adult photographed flying over the Learning Forest at the Botanic Gardens on 25 September.
