between Mexico and Ecuador are: Volcano Irazu, Costa Rica, June 8 

 (Cherrie); La Estrelle de Cartago, Costa Rica, November 5, 1907

 of observation. 



Not many years ago the Baird sandpiper was considered merely 

 accidental on the Atlantic coast. The past few years have witnessed 

 a great increase of data. It is now known to be a regular and not 

 rare migrant east to Lake Huron (Wood), Lake Erie (Todd), and the 

 western end of Lake Ontario (Nash), and there are 50 or more printed 

 records for the Atlantic coast region, from Four Mile Run, Va. 

 (Matthews), north to Digby, Nova Scotia (Macoun). What becomes 

 of these Atlantic coast birds is not yet known, for the species seems to 

 be unrecorded in the United States south of the Ohio River and east 

 of Mississippi, and is not known in the West Indies. I|; ranges regu- 

 larly west to British Columbia (Brooks), but to the southward the 

 flocks seem to pass inland west of the Sierra and are common in 

 Nevada (Ridgway) and Arizona (Henshaw), but rare in California, 

 where it has been taken at Point Pinos (Mailliard) and September 8, 

 1904, at Pacific Beach (Bishop). 



Spring migration. — The Baird sandpiper is a much earlier migrant 

 than its eastern relative, the white-rumped. It appears on the coast 

 of Texas in early March (Brown) ; the average date of arrival in central 

 Nebraska is March 24, eariiest March 19, 1890 (Powell); Loveland, 

 Colo., March 29, 1890 (Smith) ; southern British Columbia, April 29, 

 1889, and 1905 (Brooks); Indian Head, Saskatchewan, May 9, 1892 

 (Macoun); Fort Resolution, Mackenzie, May 19, 1860 (Kennicott); 

 near Dyer, Alaska, May 15, 1882 (Hartlaub); Kowak River, Alaska, 

 May 20, 1899 (Grinnell) ; Point Barrow, Alaska, average of three years 

 May 29, earhest May 28, 1898 (Stone). The date of arrival at Point 

 Barrow is worthy of notice, for at this time the birds' breeding grounds 

 on the tundra were covered deep with snow, and it had to wait some 

 weeks before it could begin nesting. The earhest eggs at Fort 

 Anderson were found June 24, 1864 (MacFarlane) ; the next year,- 

 young were noted July 5, and downy young were taken at Point 

 Barrow July 16, 1898 (Stone). 



The species remains in Chile until the last of March (Lane), and is 

 common in Texas to the middle of May (Lloyd). A late migrant was 

 taken June 1, 1903, at Iguala, Guerrero (Nelson and Goldman). The 

 last usually leave Nebraska before the first of June, but in 1900 one 

 was seen at Lincoln on June 29 (Wolcott). The last was noted at 

 Indian Head, Saskatchewan, June 2, 1892 (Macoun), and at Fort 

 Chipewyan, Alberta, June 1, 1893 (Russell). 



Fall migration. — Several flocks already in fall migration were seen 

 at Great Slave Lake, Mackenzie, July 10, 1901 (Preble). Since the 

 earliest young are not hatched until the first week in July, it is evident
