same neglected corn which proved such an attraction to Mourn- 
ing Doves on the West Subdivision was also the reason for the 
presence of Red-headed Woodpeckers there. Throughout July 
these birds were noted in twos and threes on the field. 
Colaptes auratus luteus. Northern Flicker. The Flicker 
found ants on the subdivisions and was a more or less constant 
member of the bird fauna there. Observed there October 4, 1925, 
on April 23, 1926, and more or less regularly until July 17, 1926. 
Chordeiles virginianus virginianus. Nighthawk. The first 
flew over the area on May 21, 1926, several on May 31, and no 
evening’s observation from that time until July 15, failed to note 
em. 
The marshes to the south, the stagnant water of the open, 
newly laid sewers of the subdivision, produced myriads of mos- 
quitoes. These, after the first of June, were the attractions for 
the Nighthawks. They caught mosquitoes by flying close to the 
weeds and grasses. 
After the Larks had closed their vesper recitative and the 
toads had begun to trill, the flickering white wing-bars of the 
Nighthawk were the only active bird elements in the evening 
dusk of the subdivision. 
Chaetura pelagica. Chimney Swift. Through June and July 
the Swifts found good hunting in the air, high above the sub- 
divisions. 
Tyrannus tyrannus. Kingbird. Though there was no suit- 
able nesting territory in the immediate vicinity, the King-birds 
frequently perched themselves upon a weed stem of the margins 
of the Lark territory. From one to three were noted frequently 
from June 5 to July 17, 1926. 
Otocoris alpestris alpestris. Horned Lark. ‘This northern 
relative of the Prairie Horned Lark may have occurred more 
frequently on the subdivisions than I have definite records for. 
During late February, in March and in April roving bands of 
Larks were noted long after the majority of O. a. praticola had 
established territories, and had mated. Most of these groups 
were too timid to allow approach sufficiently close for observa- 
tion. They may have been OQ. a. alpestris, or O. a. praticola 
migrating to more northerly homes, or young praticola still un- 
established and unmated. 
However, on April 9, 1926, a flock of ten to fifteen seemed
