"^^"4^] THAYER AND BANGS — BIRDS 13 



eggs lay in a slight depression, on the level, mossy ground, in a 

 dry, high, larch forest. Both parent birds were present, and both 

 had acquired the habit of alighting and perching in the tree-tops. 

 This was the only nest of the species found in such a situation. 



In June, at the Island Delta of Kolyma, there was a flock of about 

 a hundred non-breeding birds. 



Charadriidae. 

 Phalaropus fulicarius (Linn.). 



Sixteen specimens, of both sexes and every stage of plumage, 

 were obtained at the following localities and dates : Nijni Kolymsk 

 June 1, 1912; Sebddij Sound, July 20-21, 1912; Gape Serdze, 

 Aug. 23, 1911; Tenkurgin River, Aug. 29, 1911; Irkaipij, Sept. 5, 

 1911. 



The first spring arrival noted at Nijni Kolymsk was on June 1. 

 July 30 was the earliest date upon which young birds able to fly 

 were seen ; this was at Chaun Bay. 



We have compared this series very carefully with an immense 

 number of American birds, and can find no tangible differences. 

 American birds average very slightly larger, with slightly bigger 

 bills, but individual specimens cannot be told apart. 



Lobipes lobatus (Linn.). 



Two adults in breeding plumage, — a male, Sebddij Sound, July 

 20, 1912, and a female, Nijni Kolymsk, May 30, 1912. 



The northern phalarope was first seen in spring at Nijni Kolymsk 

 on May 30. At Kalaschkowo, Kolyma, June 22, 1912, a set of 

 three nearly fresh eggs was taken. Young birds on the wing were 

 first noticed at Chaun Bay, July 30. 



The two skins are similar in every way to adult specimens from 

 Finmark, and average, as in the case of the red phalarope, just a 

 trifle smaller than American birds. The differences are trifling,
