. Birds of New York. Birds. 168 NEW YORK STATE MUSEUM the month of August. These flights usually progress in a southwesterly direction. This would seem to indicate that the principal line of migra- tion extends down the Ohio-Mississippi valley. I have noticed these flights several years in Erie county passing in this same general direction. Habits. The Nighthawk is much more diurnal in habits than the Whippoorwill, and frequently is seen fl3dng about in the bright daylight high in the air, with slow, measured wing strokes, occasion- ally darting swiftly downward; at other times with rapid flapping of the wings succeeded by a graceful soaring. The wings appear ex- tremely long and crooked. As the birds fly about seeking for beetles, flies, moths and other in- sects, they occasionally give voice to a loud nasal " peent, peent," and sometimes to a squeaky, querulous " ; In the mating season when the Nighthawk is wheeling about high in the air, he suddenly plunges headlong toward the earth P^°'° ^y ^"^y^-B^"«y but, just before striking the ground, Nighthawk's eggs on gravel roof ° suddenly glides upward again, at the same time producing a roaring sound by the air rushing through the wing feathers, which has been likened to the noise made by blowing across the mouth of an empty bottle, or the bunghole of a barrel. Although the Nighthawk is frequently seen in cloudy weather during the middle of the day, he certainly prefers to hunt in the evening and early morning, and his notes are often heard late at night as he hawks about for insects high in the air. Like the Whippoorwill, the Nighthawk.
