it is likely many of these birds breed. I bave often 

 observed this species resting lengthwise and cross- 

 wise on a horizontal limb of a large tree in the 

 middle of Phillips Square, in the city, and I shot a 

 female specimen which was resting lengthwise on a 

 dead limb of a tree on the spur of Mount Royal 

 August 18, 1888. When resting on branches of 

 trees they generally sit lengthwise, as their feet are 

 not adapted for perching. In the evening till dark, 

 and early morning, the nighthawks feed on the 

 wing with erratic flight, and uttering a harsh note, 

 occasionally swooping downward, like a meteor fall- 

 ing through the air, at the same time making a 

 loud buzzing sound, which is caused by its wings 

 when about mounting in the air on the upward 

 curve of its flight. I have often seen them flying 

 during the daytime, but on such occasions it is very 

 likely that they have been disturbed in their resting- 

 places, as their habits are nocturnal, being adapted 

 to their food supply of the numerous moths that 

 fly at dusk.
