Open Nests on the Ground 
within the past ten years.” In Ohio the nesting season begins 
about the end of March. 
420. Night-hawk; Bull-bat: Chordeiles virginianus 
(Gmel.) 
Adult 6—Upper parts dark blackish brown mottled with buff ; 
wings dark brown with conspicuous white patch; breast 
black, feathers tipped with white or buff; throat white ; 
belly grayish white, barred with black ; tail dark brownish, 
barred with buff, a white band near the end of all but the 
two middle feathers. 
Adult 2—Nearly the same, the throat being buff instead of 
white and no white on tail. Length—10.00. 
Breeding Range—Throughout the Eastern States. 
There is no nest, the eggs, two in number, being laid on the 
bare ground in a field, on rocks, or even on the flat roof of a 
building either in the country or in the big cities. The eggs are 
olive-buff, light gray, or greenish, with numerous irregular 
blotches and specks or thickly marked with evenly distributed 
spots of darker gray, olive, and purplish. Size—1.20 x .86. See 
Fig. 9, Plate B. 
These birds, though called Night-hawks, do a great deal of 
flying during the daytime, especially towards the end of sum- 
mer, when they may be seen at almost any time of day flying 
about over the open country. They are sometimes mistaken 
for the whip-poor-will, though the white patch on the wing and 
the white throat should serve to identify them. Their flight is 
also very different, and generally, though by no means always, 
they fly higher than the whip-poor-will. Late in the afternoon 
they may be seen flying high above the city, looking almost like 
large bats. 
The eggs are exceedingly difficult to find, as their colouring 
so closely matches the ground ; even when the bird is startled 
from the eggs and tries, as many birds do, to divert attention 
from the eggs to herself, bya pretended broken wing or leg, it 
is often only after a long and careful search that the eggs are 
discovered. 
The nesting season in New England begins about the end 
of May.
