NORTH AMERICAN MIGRANTS. 



The coast and the lakes and marshes of the tableland of Peru form 

 the winter home or migration stations for a number of North American 

 shore birds. Taczanowski records some 28 species, but of land birds 

 comparatively few reach this country, only 15 being given by 

 Taczanowski. 



Our work having been done largely in the summer months we took 

 comparatively few of these migrants. Totanus melanoleucus is 

 recorded from Tinta and Tungasuca by Sclater and Salvin, Helodnmias 

 solitarius from Santa Ana by Berlepsch and Stolzmann, while Watkins 

 secured two male Spotted Sandpipers at Galea, near Cuzco, on April 

 25, one of which had the sexual organs much enlarged. 



The following North American land birds are recorded beyond: 



Empidonax trailli alnorum. 



Vireosylva olivacea. 



Dendroica caerulea. 



Wilsonia canadensis. 



Piranja rubra rubra.

!• The richness of the Puna Zone avifauna of Peru as compared with that of Colombia is shown by the 

 statement that only 15 genera and 18 species were found by us in the Paramo or Puna Zone of the last- 

 named country. This comparatively limited life is due to the small extent of the area contained within 

 the zone and also to its remoteness from the region in which Puna birds have their geofrrapliic origin.
