P. De Benedittis 1965 Colcerius laponicus 19 June Barrow, Alaska - a overhang on a high polygon facing W and was open only to the west. The egg was cool when found and now cold; I was about 4 inches from the nest & may have been kicked out when I flushed it, 7:30 12" true. 20 June Today when I looked in the nest there was a lemming looking out at me! Found a 2nd egg outside the nest (after the 1st found outside the nest) and an egg (brighter, more-ruptious spotted) inside the nest. Don't quite know what is going on here! No other evidence of nesting except for song. 21 June The nest now empty. Hamilton found a 2nd nest containing 5 eggs. It is in a lemming (vireo?) on the W side of a raised polygon at the top of the slope; the nest is bulky and lined with 2-4 owl feathers. Considerable song but no other note- worthy display. 22 June A lemming has run its Barrow down through the 5 egg nest above, destroying the entire contents. Song was little in evidence today and there was little other display noted. Some birds are still for from being attached to an area. 23 June Very silent. One seen being chased by a Dunlin. 24 June Saw one being chased by a dunlin, g.v. Little change in activity today. 25 June Not very noisy today. Hamilton found 3 nests than not seen, ? now.
