The Whip-poor-will, the name by which this bird is familiarly known in North 
America, is common during the summer months throughout the Eastern States and as 
far north as Montreal and Manitoba. In its northern migration it first shows itself 
in the Southern States early in March, but in more northern localities its appearance is 
delayed till the end of April and even the early part of May®. After the breeding- 
season, ou the approach of autumn, it leaves for the south again in September. The 
winter months are passed in Mexico and Guatemala: the port of La Libertad in 
Salvador, on the shores of the Pacific, is the most southern point to which we have as 
yet traced it; here Mr. Richardson secured an example in February. Though chiefly 
found in Eastern Mexico it is not confined to that region, as Mr. Ridgway states, for we 
have specimens from Sinaloa and Tepic, on the western side of the Mexican Cordillera. 
In Guatemala it is not by any means abundant, or at least not much in evidence. 
Our only specimens from that locality were obtained in Vera Paz on the eastern side 
of the country. 
According to Brewer® the Whip-poor-will makes no nest, but lays its eggs in the 
thickest and most shady portions of the woods amongst fallen leaves in a hollow exca- 
vated for that purpose or on the leaves themselves. The eggs, two in number, are 
oval, of a creamy-white colour, irregularly spotted and marbled with lines and patches 
of purplish-lavender mingled with reddish-brown, the latter much more distinct.
