and these mostly from southern stations. From southeastern Alaska there are 

 but two or three. The Baird Sandpiper seems to be practically unknown east of 

 the Mississippi during the spring migration. At points farther north large flocks 

 foraging on masses of floating ice were noted by Preble at Lake Athabasca, Can- 

 ada, May 25, 1901 (N. Am. Fauna, no. 27, 1908, p. 321) ; and Grinnell (Pac. 

 Coast Avif., i, 1900, p. 23) records a female from Kowak River, Alaska, May 20, 

 1899. 



The species arrives at its breeding grounds in the Arctic during the last 

 week in May. Brooks noted the first arrival at Demarcation Point, on the Alas- 

 ka-Canada boundary, on the Arctic Coast, on May 23, 1914, while the average 

 date of arrival for three years at Point Barrow was May 29. At Griffin Point, 

 Arctic Alaska, the first birds were noted May 31, 1914. Dr. R. M. Anderson

took a specimen at Collinson Point, Arctic Alaska, on May 31, 1914. 



According to the A. O. U. Check-List (1910, p. 114) the Baird Sandpiper 

 "Breeds along the Arctic Coast from Point Barrow to Northern Keewatin". The 

 most eastern record that I have been able to find is that of Collinson (1853) at 

 Cambridge Bay on Victoria Island, Franklin. However, recent evidence indi- 

 cates that the breeding range of this species is not entirely restricted to the west- 

 ern hemisphere, as had been supposed. (See fig. 26.) 



On June 11, 1913, an adult male Baird Sandpiper was secured by our party 

 at the head of Providence Bay, East Siberia (Brooks, Bull. Mus. Comp. Zool., 

 lix, 1915, p. 385). John Koren (Warbler, xi, 1910, p. 10) states: "On July 3 

 [1909] I found a nest of Baird Sandpiper on the high, stony plateau on the south 

 end of the island [Koliuchin Island, northeast Siberia] , the eggs about five days 

 incubated". Thus it appears that the species also breeds along the coast of north-
