Picoides arcticus. 1871. Maine (Lake Umbagog). June 3- Three specimens taken. One which I shot June 14 14. was hammering at the prostrate trunk in a windfall on the shore of the Lake. The tapping roll of this species is different from that of the Yellow-bellied Woodpecher. 1873. July 31. Found an adult male with a young in first plumage feeding among the stubs on the bank of the River below the house. Sept. 7.

A female shot to-day would evidently not have laid for several weeks. 1879. June 4. A nest near the bank of Cambridge River with young uttering the querulous chatter common to all young Wood- peckers. Both parents were feeding them. About three minutes usually elapsed between the departure of one and the return of the other. As the male emerged from the hole his coal black head and yellow crown presented a fine appearance. Once he seemed suspicious of my pres- once, clinging against the trunk of the tree and twist- ing his body about incessantly. After leaving the spot I heard him calling continuously for sometime, running the usual kluck into a harsh, rolling clamor that I have never heard before. The hole was a very neat one about the size of that made by the Hairy Woodpecker. It was in
