Not many years ago the Baird sandpiper was cuaaddored merely 
accidental on the Atlantic coast. The past few years have witnessed 
@ 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. It 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, earliest 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, earliest 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 earliest eggs at Fort 
Anderson were found June 24, 1864 (MacFarlane); the next year, 
young were noted July 5, sail 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 Miabracke 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
