on the bare ground in dense growths of scrub oak or in second 
growth timber on burnt over hillsides. Three sets in the Tin- 
dall collection were taken on the following dates: May 7, 1901, 
May 20, 1903, June 12, 1915. 
It is numerous about Swope Park and Dodson and along the 
river bluffs. 
PHALAENOPTILUS NUTTALLI NUTTALLI (Audubon). Poor-will. 
Formerly a rare summer reside 
Bush reports that the Poor-will formerly nested on the open 
country near Swope Park and Dodson. He frequently heard the 
mournful cry of this bird in the neighborhood of Grandview. 
Efforts to find the Poor-will in this county during the summers 
of 1916 and 1917 proved unsuccessful, though it may yet be 
found still occasionally breeding on the prairie regions of south- 
ern Jackson County. 
CHORDEILES VIRGINIANUS VIRGINIANUS (Gmelin). Nigh 
Abundant migrant and fairly common summer resident. 
The first Nighthawks arrive usually on the 26th, 27th or 
28th of April followed by great numbers of migrants during 
the next three or four weeks. The southward moving flocks 
pass through during September and early October. 
Like other members of this family the Nighthawk builds 10 
nest but lays its two eggs on the bare ground or rocks or on the 
flat roofs of the tall buildings in the business district of the 
city. As a breeder it is found chiefly along the northern bound- 
ary of the county but ranges out over the prairie country to 
feed. It is probable that it may nest along the rocky ledges in 
the Swope Park district. 
CHORDEILES VIRGINIANUS HENRYI Cassin. Westen Nighthawk. 
Regular but not numerous migrant. 
Resting flocks of migrating Nighthawks have often been seen 
to contain birds of varying degrees of pallidity. Some of the 
individuals are only slightly lighter in color than the ene 
birds while others are so very decidedly lighter that they ean 
be distinguished as far as the flock is visible. There is Very 
little doubt that these forms are the Western and Sennett st 
species but it would be well to take specimens.
