China- Eastern Imperial Eagle

The grand Aquila eagles are amongst my favorites and here is a single theme cover featuring the Eastern Imperial eagle  ( Aquila heliaca). The Austrian-Hungarian empire once chose this large bird to be its heraldic symbol. Despite this, Imperial eagles are threatened with extinction in Southern Europe . Imperial eagles feed on hares, rodents and other small animals.
