Singapore Raptor Report, July-September 2017

PF, 170817, Ubin, Xu Weiting

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.

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’.

Many thanks to everyone for their records and to Xu Weiting and Laurence Eu for the use of their photos.

Eastern Imperial Eagle, juvenile, Pulau Ubin, 28 Dec 2016, by Robin Tan

Summary for migrant species:

An uncommon Grey-faced Buzzard (adult) photographed by Thio Hui Bing on the 1st on Pulau Ubin after rain was a good start for the month. The next day, on the 2nd, two rare raptors showed up: a grey morph Oriental Scops Owl photographed by Gavan Leong in the daytime, also on Pulau Ubin and a juvenile Black Kite photographed by Francis Yap at Jelutong Tower.

Not to be outdone, a very rare Amur Falcon was photographed by Yip Peng Sun at Yishun Dam on the morning of the 16th – this being the second record for Singapore since the first occurrence on 21 Nov 2007.

The streak of rarities culminated with a juvenile Imperial Eagle, again on Pulau Ubin. The last record being on 18 Nov 2001, 15 years ago. First photographed on the 19th, the Imperial Eagle was relocated on the 27th at the same spot and appeared there everyday till the 31st, giving birders here a great opportunity to see this rarity. A juvenile Imperial Eagle photographed on the 24th at the eastern part of Singapore main island was most likely the same individual. As is the case with migrant eagles, this individual was occasionally mobbed by resident House Crows and Brahminy Kites.

Eastern Imperial Eagle, juvenile, Pulau Ubin, 28 Dec 2016, by Frankie Cheong

A dark morph Booted Eagle was still wintering at Pulau Punggol Barat and the nearby areas, being recorded on the 3rd, 10th, 17th and 26th. Two Ospreys were recorded around the usual areas near the northern coast of Singapore. For the Accipiters, six Japanese Sparrowhawks were recorded, but none for the Chinese Sparrowhawk. Five Peregrine Falcons (3 juveniles, 1 adult, 1 un-aged) were recorded around the island, quite a good number for this uncommon species.

A total of 36 Black Bazas were recorded on the northern areas from Sungei Buloh to Pasir Ris, the largest flock being 15-strong at Punggol Barat. For the Oriental Honey Buzzard, 45 were recorded, the largest flock comprised 11 birds at Sungei Buloh on the 3rd, probably on migration. On the 15th, there was a sight report of a juvenile Rufous-bellied Hawk-Eagle, which cannot be verified due to the possibility of confusion with other similar-looking species.

White-bellied Sea Eagle, immature, Pulau Ubin, 27 Dec 2016, by Tan Gim Cheong

Highlights for sedentary species:

By the 22nd, the Grey-headed Fish Eagle chick on the nest at Little Guilin had fledged – another successful nesting for the species at the same locality. Other records of this fish eagle came from Kranji Marshes (on 10th & 26th) and Pulau Ubin (on 15th & 29th).

The Crested Goshawk was recorded from the Botanic Gardens (adult on 3rd & 13th), West Coast Park (juvenile on 7th & 20th) and Sengkang Floating Wetlands (juvenile on 17th).  There were 2 torquatus Oriental Honey Buzzzards; the adult tweeddale morph recorded at Pasir Ris Park the previous month was still around on the 10th, 17th and 21st, while a juvenile tweeddale morph first recorded last month at Ang Mo Kio was photographed at the nearby Bishan Park on the 24th and 25th.

For the Changeable Hawk-Eagle, it was notable that nesting was observed at Mount Faber on the 20th. The White-bellied Sea Eagle, Brahminy Kite, and Black-winged Kite completed the roundup for the month.

Singapore Raptor Report – Late Spring Migration, April-June 2016

WBSE, 210616, Sentosa, James Tann

A rare photo of an adult and a young White-bellied Sea Eagle “cartwheeling” over Sentosa, 21 Jun 16, by James Tann.

Summary:

On 21st June, James Tann captured a rare series of photos of two talon-locked White-bellied Sea Eagles ‘cartwheeling’ through the air over Sentosa. Some books described this as ‘talon-grappling’ and ‘tumbling’. Interestingly, an adult and a young eagle was involved in this instance whereas this behaviour is usually attributed to mated pairs but only mature adults have been known to form breeding pairs.

Now, for the migrants. Five migrant raptor species were recorded in the April to June period. Four of them – the Osprey, Oriental Honey-buzzard, Japanese Sparrowhawk and Peregrine Falcon were also recorded during last year’s late spring migration. The notable addition this year was the Rufous-bellied Eagle: a juvenile was photographed at Lorong Sesuai on 23 April enjoying a meal.

Of the 14 orientalis  Oriental Honey Buzzards recorded, 11 were juveniles (there were 10 in the same period last year), one was an adult female while the remaining two were not aged. Most of the juveniles were moulting their flight feathers (most were showing new P1 & P2, counting from the inside). It is worth mentioning again that juveniles are known to ‘over-summer’ in the tropics.

Only one Japanese Sparrowhawk, an adult female, was recorded on 2nd April. Two Ospreys were recorded at Sungei Buloh Wetland Reserve in Apr and May, but none in June; elsewhere, there was a record at Singapore Quarry in Apr and another record at Seletar Dam in May.

Two Peregrine Falcons were recorded in April – one at Pulau Ubin on 8th and another at Chinatown on 21st. An ernesti Peregrine Falcon returned to its usual haunt at the rooftop of buildings at Church Street on 26 May and a juvenile, likely also ernesti, flew over Punggol Barat on 15 June.

Back to the resident raptors. The usually encountered resident raptors were all present. Notable records included the locally rare Crested Serpent Eagle which was recorded thrice in April (Kent Ridge Park, Ubin & Bidadari), twice in May (Sungei Tengah & Malcolm Road), and once in June (Chancery Lane).

Also, April to June was a good quarter for the Crested Goshawks – in April, two juveniles were photographed at the leafy compounds of the Singapore Zoo and an adult male was seen collecting twigs at the Southern Ridges where two nest structures were seen; in May, the species was recorded at the Botanic Gardens and Bishan; and in June, a total of four juveniles from two different nests were recorded at the Botanic Gardens.

Many thanks to everyone for sending in / sharing their records; and to  James Tann for the use of his photo.

Singapore Raptor Report – December 2015

OHB, 261215, Bidadari, Nicholas Tan (one of 2 birds)Oriental Honey Buzzard, juvenile, Bidadari, 26 Dec 15, by Nicholas Tan. 

Summary for migrant species:

For the month of December, a total of 145 migrant raptors of 11 species were recorded. The most abundant was the Oriental Honey Buzzard with 89 birds, followed by the Black Baza with 36 birds and the Japanese Sparrowhawk with 7 birds – no surprises here, except for the one-eyed Japanese Sparrowhawk at Tuas photographed on the 7th – how does it catch prey without depth perception? There were 3 Ospreys at Sungei Buloh Wetland Reserve, one of the usual sites for this common migrant.

Next up – the uncommon raptors. A Jerdon’s Baza was photographed at Tampines Eco Green on the 19th and the 21st. A juvenile pale morph Common Buzzard – an uncommon bird despite its name – was photographed at Tuas on the 8th. A juvenile Chinese Sparrowhawk was photographed between the 13th to 21st at Bidadari; the small raptor had brown leather ties (known as falconry jesses) around its tarsus – could it have escaped from its masters in North Asia and followed its instinct to migrate? The origins of this particular individual may remain a mystery. There were 3 records of the Peregrine Falcon, 1 at Mandai mudflats, 1 at Sungei Buloh Wetland Reserve and 1 that returned to the 35th floor balcony of Vista Residences, the last bird was also recorded in the previous season.

Lastly, the rare raptors. A juvenile Black Kite was photographed on the 18th at Sungei Buloh Wetland Reserve and an older individual photographed on the 29th at Punggol Barat. A juvenile Rufous-bellied Hawk-Eagle was photographed on the 22nd at Dairy Farm Nature Park. There was a sight report of a Greater Spotted Eagle, a lifer for the observer who was undergoing basic military training at Pasir Ris Camp, on the 31st.

Highlights for sedentary species:

By the end of December, the young Grey-headed Fish Eagle on the nest at Little Guilin had grown to be as big as its parents. Other records of this fish eagle came from Venus drive on the 2nd and Lorong Halus Wetland on the 31st. The Crested Goshawk was recorded from Pasir Ris on the 2nd, Sentosa on the 25th and Little Guilin on the 27th, all being adults, while an un-aged individual was recorded on the 16th at the Botanic Gardens. There were 3 torquatus Oriental Honey Buzzzards; a tweeddale morph was photographed at Pasir Ris Park on the 9th and 11th, a juvenile normal plumage type at Park East Condo on the 16th and an immature at Bidadari from the 20th to the 30th. The White-bellied Sea Eagle, Brahminy Kite, Changeable Hawk-Eagle and Black-winged Kite completed the roundup for the month.
