FAMILY FURNARIIDAE III 



tail 55.0-60.0 (57.9), culmen from base 21.9-24.4 (23.4), tarsus 

 21.5-23.2 (22.3) mm. 



Resident. Rare, known in Panama from a few records in the 

 higher forests in the Subtropical Zone on the great volcano in western 

 Chiriqui. The only record is of two specimens, a male and a female, 

 collected by W. W. Brown, Jr., at an elevation of about 1700 meters 

 above Boquete, Chiriqui, on March 19, 1901 (Bangs, Proc. New 

 England Zool. Club, 1902, p. 45). In Costa Rica also the bird has 

 been little known. Slud (Bull. Amer. Mus. Nat. Hist., vol. 128, 1964, 

 pp. 208-209) reported it "only from the northern half of the country, 

 its recorded localities . . . restricted to the subtropical belt along 

 the Caribbean slope of the Cordillera Central and the Pacific face of 

 the Guanacaste Cordillera." My only personal encounter with it in 

 the field came in the latter area on the forested summit of Cerro 

 Santa Maria. A male collected here appeared at a call in dense under- 

 growth a few centimeters from the ground. 



Belcher and Smooker (Ibis, 1936, p. 803) describe the nest of 

 Sclenrnis albigularis albigiilaris in Trinidad as a tunnel "made in the 

 tough clayey soil of a roadside bank, often of not more than a couple 

 of feet in height from the ground-level ; the tunnel is quite short, 

 a foot to 18 inches, and is considerably wider than high at the 

 entrance, which is in form a lateral oval. . . . Usually it curves 

 considerably to right or left, and terminates in a chamber floored with 

 a few stripped midribs of leaves placed side by side . . . these are 

 loose and independent of each other, not interwoven. The eggs are 

 two, broad blunted ovals, white and smooth-shelled. A pair taken 

 30 October, 1924, at the Heights of Guanapo, measure 25.2x20.3 and 

 25x20 mm."
