Species: The Blue-winged Warbler (Dendroica castanea) is more likely to be found on older farmlands, where the fields have been overgrown by trees, in bushy meadows or along the edges of second growth forests. This warbler is known to hybridize with the Golden-winged Warbler, producing two recognized hybrids known as the "Brewster's Warbler" and the "Lawrence's Warbler". Over a number of years, both hybrids' offsprings, through breeding, will return back to one of the original two bird species. At this time the Blue-winged Warbler's breeding range is moving farther northeast each year into the Golden-winged Warbler's breeding territory.
Distinctions: The male has a bright yellow head, throat and breast. Its undertail area is a yellowish-white. The nape and back is olive green, bluish-black wings and tail feathers. It has a very distinguishable bold eyeline, starting from the bill to beyond the back of its eyes. The female and the juvenile bear resemblance to the male, except in duller colours. Showing maybe darker green cap, nap and back. Other similar warblers are the Yellow Warbler and the Prothonotary Warbler, both birds that have large amounts of yellow plumage showing.
Voice: Single call note, song sound like "seeee-bzzzz, repeated over and over.
Nesting: Three to five white coloured eggs, with brown markings. The nest is usually built at the base of a tree or shrub or in shrubs low to the ground. Composed of rootlets, leaves, mosses, and lined with fine grasses and hair.

Avibase - the world bird database This site provides the user with a complete list of bird species, broken down per country, or in the example of the US or Canada, per state and province. Here, bird species names are available in other languages, a great asset to be used as a translation of foreign bird names.
ABA - American Birding Association This site represents an organization that maintains official records of all birds species that have been proven to have been seen inside the perimeters of the North American Continent and the surrounding bodies of water. Regular revised versions are posted to keep the bird list current at all times. This is the list used by all serious birders over their lifetime. You may be aware of the movie called the "Big Year". It was with this list that all the competing birders used in an attempt to set a new record as to how many bird species that could be seen by an individual birder in one calendar year.
I hope you will take advantage of these suggested websites. I have used each of them, in one way or another, throughout the years in my quest to better identify and understand our fine feathered friends.
