63O BIRDS OF THE REPUBLIC OF PANAMA PART 4 



Females (10 from Alaska, taken in May), wing 163.0-182.0 (174.0), 

 tail 70.0-80.6 (76.8), culmen from base 38.6-46.8 (42.1), tarsus 29.2- 

 32.3 (30.5) mm. 



Winter visitor from the north. Known in Panama from 3 reports: 

 a bird collected on Valladolid Rock in Panama Bay between Chame 

 and Otoque Islands (not far from Taboga) on March 3, 1969, by H. 

 Loftin and R. Crossin; a sighting by S. West of a bird almost certainly 

 this species at Fort Kobbe, Canal Zone, on April 22, 1973 (Ridgely, 

 1976, p. 98); and 1 seen by Ridgely on Isla Barco Quebrado off the 

 south coast of Coiba Island, Veraguas (Ridgely, in litt.). All three 

 were in nonbreeding plumage. The specimen (USNM no. 544832) 

 was a female with moderate fat and in heavy body molt. This species 

 breeds in Alaska and northwestern Canada and winters mostly in the 

 South Pacific, but also on rocky Pacific coasts from California to 

 Peru and on the Galapagos Islands. 



NUMENIUS AMERICANUS Bechstein: Long-billed Curlew, 

 Zarapito Piquilargo 



Numenius americanus Bechstein, 1812, in Latham, Allgem. Ueb. Vog., 4, pt. 2, 

 p. 432. (New York.) 



Winter visitor from the north. This species, which usually winters 

 only occasionally as far south as Guatemala and Honduras, has been 

 reported 3 times in the Canal Zone. Two were seen on a grassy field at 

 Fort Sherman on the Caribbean coast September 24-30, 1966, and 1 

 of these was collected (Loftin, Martin, and Powell, Condor, 1968, p. 

 91), another was seen at the same locality on December 4, 1967 

 (Ridgely, 1976, p. 104), and a fourth was seen and photographed at 

 Coco Solo from November 23 to December 19, 1975, by J. Pujals 

 (Ridgely, in litt.). These represent the most southern records of oc- 

 currence for the species. The measurements of the collected individual 

 fall within the reported mensural overlap of the two purported sub- 

 species. They are: wing chord 277 and 280; tail, worn, 105; exposed 

 culmen, 170; tarsus, 85 mm.

This species is known in Panama from 2 sight reports of males, 

 both in nonbreeding plumage, in the Canal Zone. One was seen on the 

 wet grassy fields at Coco Solo on September 29, 1968, by Ridgely and 

 observed there 3 days later by H. Loftin; the other was seen and photo-
