FAMILY SCOLOPACIDAE 405 



Others from inland localities in the Canal Zone contained a number of 

 aquatic insects, and a few ants, beetles, and Orthoptera. 



Recently this species has been separated into eastern and western 

 subspecies on the basis of a difference in color of the dorsal surface, a 

 distinction that is slight, but one that may be recognized in migrant 

 birds as well as those on their breeding grounds. Both forms come to 

 Panama, and from the numerous specimens that I have examined are 

 present in equal number. As the two may be distinguished only with 

 birds in the hand and may not be identified in life I have included both 

 in the statement of range given above. The two are similar in size. 



ACTITIS MACULARIA MACULARIA (Linnaeus) 



Tringa macnlaria Linnaeus, Syst. Nat., ed. 12, vol. 1, 1766, p. 249. (Penn- 

 sylvania.) 



Characters. — Dorsal surface grayish brown, with a brownish cast, 

 and a faint metallic gloss ; in breeding dress, with under surface more 

 heavily spotted, and the markings more intensely black. 



The typical race breeds from California, Montana, Wyoming, and 

 Saskatchewan east to Labrador, and south to southern Nevada, cen- 

 tral Texas, northern Alabama, western North Carolina, and Virginia. 

 Specimens in the U. S. National Museum indicate a winter range that 

 covers Central America, through South America to Argentina, the 

 West Indies, and the Bahama Islands. Definite specimen records for 

 this subspecies in Panama are as follows : 



BocAS DEL ToRO : Zegla, May 19, 1927. 

 Herrera : Parita, Feb. 13 and 19, 1948. 

 Canal Zone: Miraflores, May 13; Rio Indio, near Gatun, Feb. 15; Gatun 



May 8 ; and Monte Lirio, Jan. 24 ; all in 1911. 

 Panama : Cerro Azul, Sept. 18, 1953. 

 Darien : Jaque, March 17, 1946. 

 IsLA San Jose : Aug. 13 and Sept. 3, 1944. 



ACTITIS MACULARIA RAVA Burleigh 



Actttis macularia rava Burleigh, Auk, vol. 77, no. 2, Apr. 30, 1960, p. 210. 

 (Lewiston, Nez Perce County, Idaho.) 



Characters. — Dorsal surface grayer, with only a faint trace of 

 metallic gloss. In breeding dress, less heavily spotted on the under 

 parts, with the markings less intensely black. 



This race breeds from northwestern Alaska, Yukon, and western 

 MacKenzie south to Oregon and Idaho. It is found in winter mingled 

 with the other subspecies south to Peru, Venezuela, and the West 

 Indies.
