Married to a Filipina, I've visited the Philippines many times and was surprised to be told that the abundant Eurasian Tree Sparrows (Passer montanus) were "maya: the Philippine National Bird".  I thought it rather curious that an introduced species should be given that elevated position.  However, while bird-watching with my brother-in-law near some rice paddies, we saw a large flock of what he described as "maya".  These were obviously not Tree Sparrows but one of the Lonchura sp. too distant to be sure which.  In subsequent visits I saw three different species: L. malacca, L. punctulata and L. leucogastra.  Of these three, the first seems to be the most common and widely distributed.  I think it most closely resembles the front bird on the stamp.

In 1995, the Philippines declared that the National Bird should be the Philippine Eagle (Pithecophaga jefferyi).

Does anyone have a further comments for SG 2645?
