Tachycineta bicolor. 1873. Maine (Lake Umbagog). July 31. They seem to have left the locality as I have not seen any for several days. Aug. 1.

A large flock flying about the stubs about the Out- let; they have been entirely absent from Upton for at least three weeks. 1876. June 2. A nest with two eggs. " 3. Breeding in great abundance among the stubs at the Outlet. " 5. A nest containing five fresh eggs; the sitting bird proved a female. copy " " Upon shooting an Ardea herodias among the stubs many Swallows came trooping to the spot and began play- ing with the feathers scattered about on the surface of the water. " 6. Two nests, one with four the other with five eggs. The former built in an old Downy Woodpecker's hole con- sisted of only a few feathers and chips of wood; the latter in a large natural structure cavity was a beauti- ful structure lined lavishly with feathers. The birds were very bold and plucky, diving down past my head and clicking their bills. " 7. One nest containing four eggs, another six. " 8. A nest in a stub was beautifully lined with the fea- thers of Bubo virginianus. " 9. Two nests, one with four and the other with five eggs; the former beautifully lined with feathers of the adult male Hooded Merganser. " 18. Saw one pursue a Hooded Merganser actually overta- king her and harassing her as he would a flying Hawk. The duck, however, seemed to fly slower than usual. 42
