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 Ossinl- 
' ing, N. Y., October 21, 1879 (Fisher), and a late migrant was taken 
at Lake Drummond, Virginia, November 5, 1898, (Fisher). 
i 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 (MacFaxlane); 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 i is 
shown i 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. 16; 000 feat altitude (Gulaien): 
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 re retraces its spring course 
and leaves the United States to the southward of the plains region. 
It has been noted in a few places i in Mexico i 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. Itisacommon 
fall migrant in Ecuador (Salvadori and Festa), but the only records
