From left to right and top to bottom the stamps picture the following species :
- Edwards’s pheasant (Lophura edwardsi). It can be found in central Vietnam. This species was believed extinct in Wild for several decades until some were rediscovered in the forests of central Vietnam. The species was named for the French zoologist Alphonse Milne-Edwards.
- Orange-necked partridge (Arborophila davidi) that can be found in the southern Vietnam and eastern Cambodia
- Vietnames pheasant (Lophura hatinhensis) : this species is sometimes considered as a sub-species of the Edwards’s pheasant. Only small differences may be noticed between both species
- Germain’s peacock-pheasant (Polyplectron germaini) that can be found in southern Vietnam
- Crested argus (Rheinardia ocellata) which is endemic to south-east Asia
The stamps also contain the emblem of BirdLife international organization that works for the protection of endangered birds.
What is also interesting to notice on those stamps is the security perforation that takes the shape of a small bracket which is quite unusual. I already showed one stamp from Argentina with such perforation (see http://my-philately.blogspot.com/2006/09/another-large-postmark-this-time-from.html) , and I think Adrian also mentioned this type of security perforation on his blog (see Akphilately in my links section).
