Both stamps belong to a 2013 set issued by Italy and presenting birds of the Alps. The first one shows the rock ptarmigan (Lagopus muta), which has been discussed in the past. The second stamp shows the grey-headed woodpecker (Picus canus). This species is native to most of Europe and vast areas of Asia. It has ten subspecies although some authorities regard eight of them as a separate species. It feeds on insects, especially ants, but during the late autumn and early winter it also consumes plant material.

The European Goldfinch (Carduelis carduelis) has been shown on a cover from Hungary in the past. This time it is shown on this cover from Italy on a 2019 Europa stamp.

Cover from Italy

This is my first cover from Italy where bird stamps are used.  It is also my first registered cover from that country.  The set on it was issued in 1995.
Grey heron (Ardea cinerea): It can be found in some parts of Africa and in temperate Asia and Europe.  In the colder areas it is migratory.  It has four subspecies.  It feeds on frogs, fish, insects, reptiles, small mammals and other birds' chicks.
Griffon vulture (Gyps fulvus): This bird of prey lives in Asia, north Africa and southern Europe.  It can be found in Cyprus too.  In the wild it can live for 50-70 years.  It is a scavenger.
Golden eagle (Aquila chrysaetos): I already presented it on a stamp from Algeria.
White-winged snowfinch (Montifringilla nivalis): This species of sparrow can be found in southern Europe and western and central Asia.  It has four subspecies.  It feeds on seeds and insects.
