i 
your letter of April 26 inquiring about migratory birds in 
South. America is at band. February 15 and 17, 1913 at Chorillos, 
Peru and along the beach to the southward I noted a couple of 
spotted sandpipers, 2 snowy plover, 6 least sandpipers, 40 semi- 
palmated plover, 20 tumstones, 50 black-bellied plover, and 400 
sanderling. 
March 12, 1913, Lake Junin, Peru - few Baird and pectoral 
sandpipers, several yellowlegs, and many golden plover seen. 
March 25 - a blue-winged teal seen and shot at Lake Junin. 
March 31, a single golden plover, 12 pectoral, 5 3aird sand¬ 
pipers seen; 3 yellowlegs. Lake Junin. Chorillos April 11 and 18, 
few each, of tumstones (red), black-bellied plover, sanderling, 
spotted sandpipers, least and Baird sandpipers. 
August 7, 1913 - Lake Titicaca (puno), Peru - shot 3 pectoral 
sandpipers, and saw a few cinnamon teal on lake Titicaca. 
Ancud, Chiloe Island, Chile April 2, 1914, 4,000, more or less, 
sanderling, 5 Hudsonian curlew, sanderling seen often during April. 
April 23, 300 cinnamon teal in river. 
M£y 6, 100 sanderling some in good summer plumage. 
June 1, 3 greater yellowlegs, 12 Hudsonian curlew, 50 cinnamon 
teal. Buenos Aires, Argentina Sept. 8, 1914 - in city markets saw 
many dead ducks, cinnamon teal and fulvous tree ducks, as well as 
native birds, some yellowlegs, godwits and smaller snipe sometimes. 
Shooting season closed Sept. 1 was told. Mar del Plata, Argentina 
Sept. 29 - Golden plover were coming in with strong- wind, shot several 
and secured only Eskimo curlew. Few sandpipers noted as well as 
phalaropes. 
Oct. 12 - Lesser yellowlegs were in flight, also golden plover, 
pha la ropes, and pectoral sandpipers feeding; few fulvous tree ducks, 
4 white-faced tree ducks, few stilts, one stilt shot was young with 
down on tail feathers. 
The above notes from my diary include the principal observations 
made. I presume I)r. Sanford has no objection to my sending them to 
you. If shorebirds congregate in large flocks near Puno, lake Titicaca 
in migrations the natives would lively shoot them as the^ do the nc ti\e 
birds. Grebes, nudhens and ducks were on sale in public market there 
at about 5 cents each. Many of these were partly cooked to preserve 
from spoiling. They were usually picked clean of feathers to the bill.
