Dusky, Gray, and Slate-colored 
dainty, gentle, aristocratic-looking birds, a trifle heavy and indo- 
lent, perhaps, when walking on the ground or perching; but as 
they fly in compact squads just above the tree-tops their flight is 
exceedingly swift and graceful. 
Bay-breasted Warbler 
(Dendroica castanea) Wood Warbler family 
Length—5.25 to 5.75 inches. A little smaller than the English

nut. Forehead, sides of head, and cheeks black. Above 
olive-gray, streaked with black. Underneath buffy. Two 
white wing-bars. Outer tail quills with white patches on 
tips. Cream-white patch on either side of neck.

Range—Eastern North America, from Hudson’s Bay to Central 
America. Nests north of the United States. Winters in 
tropical limit of range. 
Migrations—May. September. Rare migrant. 
The chestnut breast of this capricious little visitor makes him 
look like a diminutive robin. In spring, when these warblers 
are said to take a more easterly route than the one they choose in 
autumn to return by to Central America, they may be so sud- 
denly abundant that the fresh green trees and shrubbery of the 
garden will contain a dozen of the busy little hunters. Another 
season they may pass northward either by another route or leave 
your garden unvisited; and perhaps the people in the very next 
town may be counting your rare bird common, while it is simply 
perverse. 
Whether common or rare, before your acquaintance has had 
time to ripen into friendship, away go the freaky little creatures 
to nest in the tree-tops of the Canadian coniferous forests.
