for ‘believing that,.it winters in South America, and has not been 
distinguished ;there from the eastern form. The: following state- 
ment of the winter range doubtless includes both forms, but it is not 
safe to conclude that the eastern form goes to eastern South America 
and the western form to the Pacific coast. It is known that the 
eastern form migrates to the Pacific coast. of Mexico, and it is prob- 
able that thence southward. the two forms commingle both in migra- 
tion and during the winter. The species.as a, whole ranges south in 
winter to Buenos Aires, Argentina (Barrows); to Caiza, in south- 
eastern, Bolivia (Salvadori); and to Chorillos, central Peru (Tacza- 
nowski). It occurs regularly also at this season in northern South 
America to Guiana (Quelch), Venezuela (Berlepsch and Hartert), 
and Colombia (Salvin and Godman). North of South America it is 
not common anywhere in winter, and it may, not winter at: any of 
the following, places, but it has been noted as late as December ‘in 
Porto Rico (Bowdish), Costa Rica (Todd), Yucatan (Sharpe), Vera- 
cruz (Sharpe), and northern Lower California (Stephens). 
Migration range-—A specimen was taken.in Greenland August 1, 
1878, at Kangek, latitude 64° (Hagerup); and one of the eastern 
form was taken October 28, at, San José del Cabo, Lower California 
(Brewster). e, saree. os
