Between 1993 and '97, the Philippines issued a number of domestic rate, small format sheets of stamps highlighting the country's "National Symbols". The rates changed, but the format for these stamps was consistent, only occasionally was the size of the vignette, or a different image employed for a particular symbol.
One notable exception is the national bird. The 1993 stamp shows the Maya, or red Maya (Lonchura atricapilla) as the national bird, while the 1995 stamp shows the monkey-eating, or Philippine eagle (Pithecophaga jefferyi) as the national bird.
This had me wondering, how can a country have 2 different national birds? The answer is simple...it's politics. From ABSCBN News website, "Through Proclamation No. 615 signed by then President Fidel V. Ramos, the Philippine eagle became the national bird', a national treasure found only in the Philippines', and thus a source of national pride."
So, how did the monkey-eating eagle become the Philippine eagle? Again, from ABSCBN News, "However, in 1978, former President Ferdinand Marcos , through Proclamation no. 1732 changed its name to Philippine eagle after it was proven the eagle does not feed exclusively on monkeys."
On the internet, there is still a debate going on about whether or not the Phillipine national bird should have been changed.
