322 NORTH AMERICAN FAUNA. [no. 27. 



Lake near Loon Island, July 10, when .several small flocks were seen 

 and a female was taken. The species was noted also at Fort Rae, 

 July -3. On our return trip up the Athabaska River, we found a 

 small flock at Crooked Rapid August 15, when a specimen was col- 

 lected, and another above Grand Rapid, August 22. 



In 1903 we noted a small flock near the mouth of the Athabaska, 

 June 1. The species was next seen July 13, when a few, probably 

 marking the commencement of the southward migration, appeared 

 at Fort Resolution. On their return trip Alfred E. Preble and Mer- 

 ritt Gary saw a small flock at the delta of the Athabaska, August 4, 

 and a flock of five at Fort McMurray, August 11. 



In the spring of 1904, I first saw the Baird sandpiper at Fort 

 Simpson, May 20, and took a single bird on the margin of a small 

 grass-bordered pond. It was common by May 22 and was noted 

 nearly every day up to June 1. The birds were most commonly ob- 

 served in fair-sized flocks about the fields, occasionally accompanying 

 a flock of golden plovers. During my return trip, while anchored 

 near Hardisty Island, July 31, I observed a large flock flying past 

 the steamer. 



This bird was first characterized by Coues, who based his descrip- 

 tion of the species mainly on specimens from Great Slave Lake." He 

 later recorded the species from Fort Resolution and eggs from An- 

 derson River and the Arctic coast. 6 MacFarlane speaks of finding 

 a nest containing 4 eggs on the Barren Grounds June 24, 1804, and 

 of subsequently finding other nests, though the bird was uncommon 

 throughout the region. A specimen from Fort Resolution, taken 

 May 19, 1860, by Kennicott ; one from Fort Simpson, May 26, 1860, 

 by Ross; and one from Fort Rae, by Clarke, are still in the National 

 Museum collection. An egg taken by Collinson at Cambridge Bay, 

 Victoria Land, is listed by Oates. d Reed records eggs taken with 

 the parent bird by an Indian at Peel River, June 18, 1898. e Seton 

 has recently recorded the species from Casba River and Aylmer Lake, 

 where he observed it August 8 and 13, 1907. ^ I have examined speci- 

 mens taken by Frank Russell at Fort Chipewyan in the spring of 

 1893 and at Herschel Island July 13 to August 14, 1894. 



Pisobia minutilla (Vieill.). Least Sandpiper.
