Melanerpes erythrocephalus (Linnaeus). Red-headed Wood- 
pecker. 
Common in zone seven, and a breeding species there. A 
few individuals spent the winter of 1913-1914 about the springs, 
feeding practically entirely on wood-borers taken from the oaks. 
Colaptes auratus luteus Bangs. Northern Flicker. 
Common in the border area of zone seven, and quite often 
in zone eight, where they feed on the ground. The stomach 
of one shot in the fields contained one grub ( Lachnosterna gran - 
dis), three ground beetles ( Pterostichus sp.), and several car- 
penter ants, together with a mass of unrecognizable animal, 
debris. 
Order MACROCHIRES 
Chordeiles virginianus virginianus (Gmelin). Nighthawk. 
Seen only during the evenings, when the species comes from 
across the lake to zones five and eight, to feed on the abundant 
insect life these areas offer. 
Chaetura pelagica (Linnaeus). Chimney Swift. 
This species is found only when it enters the formation in 
search of food, which it finds most abundant over the lake shore 
and in the fields. 
Archilochus colubris (Linnaeus). Ruby-throated Humming- 
bird. 
Probably more common than data indicate, as there are but 
two records of its presence in the formation: once in zone five, 
and once in eight. Very likely the species breeds within the 
limits of the area. 
Order PASSERES 
Tyrannus tyrannus (Linnaeus). Kingbird. 
Of rather wide distribution, being found in zones six, seven, 
and eight, though more commonly in six and seven. Food 
consists of any passing insect, apparently, from the small Chi- 
ronomus to May beetles. 
Myiarchus crinitus (Linnaeus). Crested Flycatcher. 
Several seen during the spring migrations in the inner area 
of zone seven. Does occasionally nest within the limits of the 
formation.
