The stamp, issued in 2025, depicts the endangered spoon-billed sandpiper (Calidris pygmaea). The species has already been presented.

Thank you Beatrice!

 

Thank you Mildred!

Issued in 2011, the stamp features the white-breasted waterhen (Amaurornis phoenicurus), which is native to south and southeast Asia. It has five subspecies. It feeds on insects, spiders, small fish, aquatic invertebrates and seeds, shoots and roots of marsh plants. 

Issued in 2007, these stamps depict the yellow-rumped flycatcher (Ficedula zanthopygia) and the stork-billed kingfisher (Pelargopsis capensis).

The yellow-rumped flycatcher can be found in eastern Asia and it is migratory. The male, depicted on the stamp, is more brightly coloured than the female. The latter is of olive-green or greyish colour while the former has black upper head, wings and tail, white supercilium and wingpatch and bright yellow throat and belly. It feeds on small invertebrates.

The stork-billed kingfisher is a large kingfisher native to southwestern Asia. It has thirteen subspecies. It feeds on fish, crustaceans, frogs, lizards, rodents, insects and young birds.

We have seen the black swan (Cygnus atratus) in the recent past. Here, a pair is featured on a miniature sheet issued in 2009 celebrating Singapore's botanic gardens.

Thank you Terence for yet another great cover. The whole 2010 Kent Ridge Park Heritage Trail set of four was used and canceled with roller datestamp. It was also missent to Sri Lanka. Unfortunately the postmark applied by Sri Lanka Post is not very clear in the scan.
Straw-headed Bulbul (Pycnonotus zeylanicus): This vulnerable songbird can be found in Singapore, Brunei, Thailand, Burma, Malaysia and Indonesia. It can be found in low trees and shrubs along the banks of rivers and streams, within forest, plantations, gardens, scrubs, reedbeds and mangroves. It feeds on berries, fruits and small invertebrates.
White-bellied Sea Eagle (Haliaeetus leucogaster): I wrote about it in a previous post.

Thank you Terence for this great cover from Singapore. Two stamps from a 2007 set are used.
Golden-backed Three-toed Woodpecker (Dinopium javanense): This species is also known as Common Flamed-back Woodpecker. It can be found in tropical and subtropical forests in Singapore, Brunei, China, Malaysia, Philippines and other neighboring countries.
