Singapore Bird Report – October 2020

by Geoff Lim & Isabelle Lee.

The highlight of October 2020 was the discovery of a new species for Singapore – the Common Swift, plus the rare Chinese Blue Flycatcher and Red-footed Booby. Most of the action was centred around Henderson Waves, as many birders welcomed the arrival of migratory raptors, among other birds. More about the major sightings of raptors can be found here in the October Raptor Report.

Common Swift – new species for Singapore

The Common Swift, Apus apus, is a large swift with a long, deeply forked tail and sharply pointed wings, and a small off-white throat patch. There are two subspecies, the nominate A. apus apus which is distributed in Europe and winters from Congo, Tanzania, Zimbabwe and Mozambique in Africa, and A. apus pekinensis, which is found in Central Asia, through the Himalayas and North China, and wintering in South and East Africa, particularly in Botswana and Namibia (Chantler et al, 2020).  The race pekinensis is found in the Himalayas at 1500–3300 m, foraging to 4000 m, and recorded migrating at 5700 m in Ladakh.

Incredibly, not one, but two sightings, with photographs, were reported – one on 9 October 2020 by Richard White, Francis Yap & Martin Kennewell from Jelutong Tower, which was the first record for Singapore; followed by another on 27 October 2020 by Keita Sin, Tan Gim Cheong & Deborah Friets from Henderson Waves. There were no prior records of the species in Singapore. A long-distance migrant, reports of vagrants have been noted in oceanic islands (Chantler et al, 2020). It remains to be seen if we would see more visits by this wandering species in Singapore and Southeast Asia.

Central Catchment Nature Reserve (CCNR) and Fringe Parks

On 31 October 2020, a Lanceolated Warbler, Locustella lanceolata, was spotted within the allotment gardens of Punggol Park by Andy Chew and this difficult to see skulker drew many other birders, but promptly disappeared the next day.

Singapore Strait

Two pelagic trips were made in October 2020, on the 4th & 18th, by Francis Yap with two different groups of birders. Due to COVID-19 restrictions, these pelagic trips were kept within Singapore port limits. For the second month, practically all the seabirds recorded could be treated as Singapore records. The most significant find was an immature Red-footed Booby, Sula sula, spotted by Martin Kennewell, during the trip on 4 October 2020.

The Aleutian Tern, Onychoprion aleuticus, was recorded on both trips, with approximately 24 birds on the 4th, and between 22-28 birds on the 18th. At least 34 White-winged Terns, Chlidonias leucopterus, were recorded on the 4th, and 113 birds on the 18th when a flock of 40 were feeding around the boat and a second group of 64 were roosting on a buoy. One Common Tern, Sterna hirundo, was recorded on the 4th, and two on the 18th.
