White-crowned Sparrow Zonotrichia leucophrys
4 May 2013
We spotted our first White-crowned Sparrow in the back yard yesterday. This is a fairly large sparrow that migrates through our area, spring and fall, remaining for a a relatively short time before moving on. This species is interesting inasmuch as most populations are migratory, but some birds in the western part of the continent are permanent residents. The White-crowned Sparrow is one of the most studied birds in North America.
