This is one of the many excellent covers I received from Wand Jia Yi (www.gonewithpostcards.blogspot.com). The stamps and m/s used were issued in 2004. On the m/s you can see Green Peafowl (Pavo muticus) which was already presented in a cover from Thailand. The two stamps depict Indian or Blue Peafowl (Pavo cristatus). This pheasant, which is native to South Asia, is the national bird of India. It feeds on grain, berries, seeds, fruit, insects, lizards, snakes and small rodents. On the first stamp you can see the leucistic variety of the species.

Thank you Li for this beautiful cover from China. The bottom stamp comes from a 2008 m/s and it shows a Formosan Blue Magpie. The other two stamps were issued in 2002.
