WHITE-RUMPED SANDPIPER 193 



Casual records. — Although probably on the migrational highway, 

 records of the white-rumped sandpiper in Central America, the West 

 Indies, and Lesser Antilles are so few that in these places it can 

 only be considered as a casual visitor. Specimens are in the British 

 Museum from Lion Hill, Panama; Momotombo, Nicaragua; and 

 Tizimin and Cozumel Island, Mexico. It also has been observed 

 or taken on the islands of Barbados (September 20 and 22, year ?) ; 

 Dominica (November 5, 1904) ; St. Lucia; Guadeloupe; Martinique; 

 Trinidad; Porto Rico (Ma}'aguez, October 2, 1900, and Culebrita, 

 April 15, 1912); Cuba; the Bahamas (Inagua, May 27, 1879, and 

 Fortune Island, August 5, 1S76) ; and the Bermuda Islands. Ex- 

 amples were reported from the Yellowstone River, Montana, August 

 8 to 13, 1878; it has been taken at Laramie, Wyo. ; in New Mexico 

 (Fort Fillmore, October, 1852, and Zuni Mountains, September 16, 

 1851) ; and there are several records for eastern Colorado. The 

 specimen reported from Oakland, Calif., was probably the Pectoral 

 sandpiper, P. maculata. One was taken at Hopedale, Labrador. 



White-rumped sandpipers have been reported in the British Isles 

 fourteen or fifteen times and a specimen was taken in Franz Josef 

 Land on June 28 (year unknown, but prior to 1898). 



Egg dates. — Arctic Canada: 14 records, June 15 to July 24; 7 rec- 

 cords, June 30 to July 12. Alaska : 2 records, June 25.

 BAIRD SANDPIPER 



HABITS 



Spring. — This sandpiper belongs to that class of birds which 

 Abel Chapman (1924) so aptly terms "globe spanners," for on its 

 migrations its traverses the whole length of both American con- 

 tinents twice a year. From its wintering grounds in Patagonia 

 it must start north even earlier than the preceding species or else 

 it must travel faster. Dr. Alexander Wetmore (192G) observed it 

 migrating past Buenos Aires on March 5 in company with white- 

 rumped sandpipers, and it has been known to reach Texas early 

 in March. From there its course seems to be northward between 

 the Mississippi River and the Rocky Mountains. A. G. Lawrence 

 tells me that it passes through Manitoba between April 28 and May 

 29; and J. A. Munro gives me, as his spring dates for southern 

 British Columbia, April 30 to May 10. Prof. William Rowan 

 (Mss.) calls it extremely abundant in Alberta about the middle of 

 May and usually gone by the 24th. It is very rare east of the 

 Mississippi in the spring. E. A. Preble (1908) saw large flocks 

 foraging on floating ice at Lake Athabaska on May 25. Dr. Joseph
