94 BIRDS OF THE REPUBLIC OF PANAMA PART 3 



lists eggs of two related subspecies of South America of about the 

 same size. A set of two of Philydor rufus columhianus in the 

 Kreuger collection from V^enezuela measure 21.0-25.7x16.0-17.6 

 mm. (While listed from "Maracay" which is in the lowlands, it is 

 presumed that they were collected in the highlands of the Cordillera 

 de la Costa, where the race columhianus is known to nest.) Four 

 eggs of the more southern race in South America Philydor rufus 

 rufus measure 22.8-24.4x17.0-18.0 mm. The eggs are white. 



AUTOMOLUS RUBIGINOSUS (Sclater) : Ruddy Leaf-gleaner, 

 Hojarasquero Garganticanelo 



Anabates ruhiginosus P. L. Sclater, Proc. Zool. Soc. London, pt. 24, 1856 

 (January 26, 1857), p. 288. (Cordoba, Veracruz, Mexico.) 



Medium size; crown rufescent, throat cinnamon. 



Description. — Length 185-205 mm. Adult (sexes alike), dark 

 above, crown and hindneck dark chestnut or dusky-maroon ; back 

 and scapulars dark tawny-brown, or maroon-brown ; wings more 

 rufescent; rump and upper tail coverts rufous-chestnut or dusky- 

 maroon ; tail chestnut or black ; side of head brownish chestnut, 

 auricular area grayer ; chin, throat, and upper breast dark cinnamon- 

 rufous, or chestnut, with the throat feathers appearing paler because 

 of the white feather bases ; rest of underparts cinnamon-tawny to 

 olive, darker on the sides and flanks, with under tail coverts rufous 

 to chocolate ; under wing coverts and inner webs of primaries and 

 secondaries cinnamon-rufous. 



These are birds of the more humid mountain forests found from 

 Mexico through Central America and northern South America to 

 Peru, southern Venezuela and French Guiana. They are nowhere 

 common, and are little known. 



Their range is not continuous, and as they vary widely geographi- 

 cally in depth of color, numerous forms have been recognized. Two 

 of these are found in Panama, one of a general dark reddish brown 

 color in western Chiriqui, and the other, much blacker, on Cerro Pirre 

 and Cerro Tacarcuna, in Darien.
