let's get to know the beautiful Bullfinch bird

The Eurasian bullfinch is a bulky bull-headed bird. The upper parts are grey; the flight feathers and short thick bill are black; as are the cap and face in adults (they are greyish-brown in juveniles), and the white rump and wing bars are striking in flight. The adult male has red underparts, but females and young birds have grey-buff underparts. It moults between July and October, but males do not have the duller autumn plumage that is typical of some other finches.The song of this unobtrusive bird contains fluted whistles, and is often described as 'mournful'.
This bird breeds across Europe and temperate Asia. It is mainly resident, but many northern birds migrate further south in the winter. Mixed woodland with some conifers is favoured for breeding, including parkland and gardens.

It builds its nest in a bush, (preferably more than four metres tall and wide), mature stands of scrub, or tree, laying four to seven eggs. It is peculiar among the Passeriformes for having spermatozoa with a rounded head and a blunt acrosome.[12]
