s which has been found was
within three feet of the ground), but when migrating it may be found in
the trees of lawns, orchards, and woodland and I have seen it among
poke-berries. The Cape May's song is a thin squeak which is compared to
the songs of the Black and White and also Blackpoll Warblers.

Show me willows over water and any day in May or June I'll show you a
Yellow Warbler. Shade and fruit trees also attract him and he may build
his cotton-padded nest in their branches or in the shrubbery below. The
song is a simple _we-chee, chee, chee, chee, cher-wee_, resembling that

thickly marked with shades of brown, are laid the latter half of May.

BLACK-THROATED BLUE WARBLER

_Dendroica caerulescens caerulescens. Case 6, Figs. 58, 59_

A true Wood Warbler, traveling through the trees with the scattered
bands of other members of his family as he journeys to and from his
summer home. This, in the northern part of his nesting range, is in
coniferous fo
