The stamp to the right was issued in 2001 and it shows a northern lapwing (Vanellus vanellus), for which I have recently written about.

The stamp to the left, issued in 2002, feautures a house sparrow (Passer domesticus) and a Eurasian tree sparrow (Passer montanus). The house sparrow has also been presented in the past. The Eurasian tree sparrow can be found in Europe and most of Asia and it was introduced to Australia and North America. It has nine subspecies. It primarily feeds on seeds but, during the breeding season, it also consumes invertebrates.
