Blue-winged Warbler - Life History

Life History

The breeding male Blue-winged Warbler is unmistakable. It is yellow above and below. The wings are gray with two white bars, and there is a black eye stripe. Females are duller, but otherwise similar.

The breeding habitat is open scrubby areas. Blue-winged Warblers nest on the ground or low in a bush, laying 4-7 eggs in a cup nest.

These birds feed on insects, and spiders.

The song is a series of buzzing notes. The call is a sharp chip.

This species forms two distinctive hybrids with Golden-winged Warbler. The commoner, genetically dominant Brewster's Warbler is gray above and whitish (male) or yellow (female) below. It has a black eye stripe and two white wing bars.

The rarer recessive Lawrence's Warbler has a male plumage which is green and yellow above and yellow below, with white wing bars and the same face pattern as male Golden-winged. The female is gray above and whitish below with two yellow wing bars and the same face pattern as female Golden-winged.

Famous quotes containing the words life and/or history:

    What is art,
    But life upon the larger scale, the higher,
    When, graduating up in a spiral line
    Of still expanding and ascending gyres,
    It pushes toward the intense significance
    Of all things, hungry for the Infinite?
    Art’s life,—and where we live, we suffer and toil.
    Elizabeth Barrett Browning (1806–1861)

    There is nothing truer than myth: history, in its attempt to “realize” myth, distorts it, stops halfway; when history claims to have “succeeded” this is nothing but humbug and mystification. Everything we dream is “realizable.” Reality does not have to be: it is simply what it is.
    Eugène Ionesco (b. 1912)
