Another cover from Malaysia. This one is registered and it traveled via Hong Kong. I also has a postmark "posted out of course" in both English and Malay. The bird stamp is coming from 2005 definitive set. Emerald Dove (Chalcophaps indica) lives in northern and eastern Australia and in tropical southern Asia. It finds on seeds and fruit. It is the state bird of India's state Tamil Nadu.

Here is another cover from Malaysia with a variety of bird stamps. From left to right:
White-faced Hill-partridge (Arborophila orientalis): This stamp is coming from 2001 Quail and Partridge set. This threatened pheasant can be found only in Indonesia's tropical and subtropical moist montanes.
White-rumped Shama (Copsychus malabaricus): I have already talked about it.
Northern Pintail (Anas acuta): The stamp was issued in 2006. This species lives in northern parts of Europe, Asia and North America. It eats plant food and small invertebrates. It is a migratory bird.
Red Junglefowl (Gallus gallus): The stamps was also released in 2001. It can be found in China, Malaysia, Philippines and Indonesia. This pheasant is the ancestor of the domestic chicken. Including the domestic one it has six subspecies. It is omnivorous.

Sometime ago I presented a cover from Malaysia with a Milky Stork stamp. Here is the rest of the 2009 set along with a stamp of the 2005 definitive set.
White-rumped Shama (Copsychus malabaricus): It lives in south and southeast Asia. It feeds on insects.

Malayan Peacock-Pheasant (Polyplectron malacense): It is a medium-sized pheasant endemic to lowland forests of Malay Peninsula. This threatened species feeds on fruit and small arthropods.

Malayan Whistling-thrush (Myophonus robinsoni): It is endemic to Malaysia. It is specialized on eating snails amongst others.

In 2009 Malaysia issued a set of 3 bird stamps and a m/s. Here is the Milky Stork (Mycteria cinerea) stamp on a cover with machine cancellation.
Milky Stork lives in Cambodia, Malaysia, Vietnam, Thailand and Indonesia near mangroves. It feeds on mudskippers, small fish, frogs and snakes. It is an endangered species and the populations in Thailand and Vietnam have already extincted.
