M. Brock 1957 Pintail Athasuk, Mead River Coal Mine, Alaska June 9 Four pintail eggs were collected from a nest which apparently originally had 6 or 8 eggs in it. Several of the eggs had been broken. The nest was located about one mile north of the waiigan. June 19 I went to look at the pintail nest Bill had told me about. It is about 100 yards SE of the coal mine. After the female flushed, 9 blue-green eggs were seen. The nest was made of down.
