Chordeiles virginianus. Maine (Lake Umbagog). 1876. June 7. In the evening of June 5 I noticed that two male Night Hawks repeatedly dove over the same spot while booming and at that time I also saw a female rise from the ground beneath; going to the place to-day I imme- diately startled the female from her eggs. The locality was a tract of burnt forest on the edge of a clearing, the fire having entirely destroyed the trees and black- ened the ground. Upon visiting the second place I star- tled another female which was also sitting on two eggs. Both birds acted similarly; they rose about fifteen yards ahead of me and fluttered off simulating lameness but not actually touching the ground as they flew. Af- ter going about thirty yards they alighted on the ground and uttered an odd clicking sound, bobbing their heads up and down in the manner of those previously seen in the garden. The first set of eggs was laid on the bare blackened ground; the second on a bed of soft, intensely green sphagnum moss. Upon shooting one of the females I found that the bare incubating space was on the breast instead of the abdomen, the latter part being thickly feathered. “ 9. At noon with the sun shining brightly numerous Night Hawks were hawking after insects and occasionally diving and booming over the middle of the lake.
