BAIRD SANDPIPER. 39 



Fall migration. — By early July the species is already moving south 

 and arrived soon after July 1, 1886, at Prince of Wales Sound, Ungava 

 (Payne), just south of the breeding grounds. During the month of 

 July the van appears all along the New England coast, and even 

 reaches Barbados (Feilden). August finds the species in Brazil 

 (Pelzeln), and the collectors near Cape Horn in 1882 recorded the 

 arrival of the first September 9 (Oustalet). 



The main part reaches the northern United States in August, usu- 

 ally about the second week ; the last leave the breeding grounds soon 

 after the 1st of September, and the birds are seldom seen on the New 

 England coast after the middle of October. One was taken at Ossin- 

 ing, N. Y., October 21, 1879 (Fisher), and a late migrant was taken 

 at Lake Drummond, Virginia, November 5, 1898 (Fisher). 

 Baird Sandpiper. Pisobia bairdi (Coues). 



Breeding range. — The Baird sandpiper has been found breeding at 

 Point Barrow, Alaska (Murdoch), in the vicinity of Franklin Bay, 

 Mackenzie (MacFarlane), and at Cambridge Bay, Franklin (Collinson). 

 These localities probably represent the real extremes of the breeding 

 range, for east or west of these limits the species is known very 

 rarely even in migration. 



Winter range. — During migration the Baird sandpiper has been 

 noted near the summit of one of the highest mountains of Colorado at 

 14,000 feet (Drew). The same tendency to seek a high altitude is 

 shown in the winter home, for this species has been taken repeatedly 

 in the high mountains of northern Chile at 10,000 to 12,000 feet, and 

 one specimen was secured at over 13,000 feet altitude (Sclater). 

 Chile seems to be the principal winter home of the species, and it has 

 been recorded here south to Talcahuano, latitude 36° 30' S. (Sharpe). 

 It is said to have occurred in Patagonia (Carbajal), but no definite 

 locality is given, and in Argentina it seems not to have been recorded 

 south of Buenos Aires (Sclater and Hudson). 



Migration range. — The route the Baird sandpiper traverses between 

 its winter and summer homes is yet to be determined. In spring 

 migration the species is practically unknown east of the Mississippi 

 River, and is abundant on the coast of Texas, on the plains, and in 

 the Rocky Mountain region. Though many individuals occur in the 

 eastern United States in fall, yet the bulk retraces its spring course 

 and leaves the United States to the southward of the plains region. 

 It has been noted in a few places in Mexico in fall: Colonia Garcia, 

 Chihuahua, September 4; Chihuahua City, October 3 (Nelson); San 

 Jose del Cabo, September 3-13 (Brewster); Janos River, Chihuahua, 

 September 5 (Wolfe); Las Vigas, Jalapa, September (Sharpe); and 

 Zacatecas, August 16 (Sharpe); here the record ends. The species is 

 not recorded for Guatemala, Honduras, or Nicaragua. It is a common 

 fall migrant in Ecuador (Salvadori and Festa), but the only records
