The only records for western Panama are of one taken at Divala, 

 Chiriqui, November 30, 1900, by Brown (Bangs, Auk, 1901, p. 358) 

 and of two from the town of Bocas del Toro, taken by von Wedel, 

 Nov. 18, 1938. Imhof recorded one at Chorrera, western Province 

 of Panama, October 11, 1942. In the Canal Zone Jewel (Auk, 1913, 

 p. 425) found this species regularly near Gatun in the fall of 1911, 

 when the birds arrived on September 12 and remained until December 

 8. The following year he saw the first one September 1. Arbib and 

 Loetscher (Auk, 1935, p. 326) recorded one there on August 17, 

 1933. 



On the Pacific side Imhof saw them at Fort Clayton October 14 

 to 18, 1942, and Hallinan (Auk, 1924, p. 309) secured one at La 

 Boca on October 26, 1915. In 1953 collectors for the Malaria Control 

 Service secured specimens at Albrook Field on October 6 and 21, 

 The bird taken October 6 is in the U. S. National Museum. 



Upland plover have been found less commonly in the spring migra- 

 tion. I recorded one on the open savanna at San Jose, above La 

 Jagua, Panama, April 7, 1950, and another at the same point on 

 April 11, 1959. There is a specimen in the American Museum of 

 Natural History that was taken at Boca de Cupe, Darien, May 3, 1915. 



These birds nest from southern Alaska and southern Manitoba 

 south to Oklahoma and Maryland. They spend the period of north- 

 ern winter in the pampas region of southern South America.
