House Sparrows

This slideshow requires JavaScript.

Along with two other introduced species, the European Starling and the Rock Pigeon, House Sparrows (also known as English sparrows) are some of our most common  birds. They are so common, in fact, that we rarely stop to appreciate their plumage, which, in the male, is quite distinctive — they have gray heads, white cheeks, a black bib, and rufous neck, whereas females are a rather dull  buffy-brown.  Male House Sparrows have a pecking order which can be determined by looking at the black bibs of the males.  Those birds with larger patches of black tend to be older and dominant over males with less black. By broadcasting  this information on their feathers, House Sparrows can often avoid fights and thereby save energy.
