 2130 meters. 



The first report in Panama for this little known species is a speci- 

 men in the British Museum received in the Salvin-Godman collection 

 labeled "Isthmus of Panama (ex H. Whitely)." The preparation 

 of the skin resembles that of E. Arce. Von Berlepsch (Proc. U.S. 

 Nat. Mus., vol. 11, 1888, p. 565) mentions "a specimen from Veragua 

 [ = Chiriqui] in my collection," possibly from the same source. Bangs 

 (Proc. New England Zool. Club, vol. 3, 1902, p. 44) received male 

 and female, collected by W. W. Brown, Jr., in 1901 above Boquete 

 in March, and on the Caribbean slope of the volcano in June. Blake 

 (Fieldiana: Zool., vol. 36, 1958, pp. 530-531) listed two males and a 

 female from above Boquete, taken at Alto de Chiquero March 13, 

 Velo, October 2, and Lerida, October 17. 



In Costa Rica the species is somewhat better known though 

 apparently far from common. Slud (Bull. Amer. Mus. Nat. Hist., 

 vol. 128, 1964, p. 206) said of it "this seldom-seen species inhabits the 

 cool and wet middle altitudes, mostly the Caribbean slopes of the 

 central highlands, also the Dota region. ... It ranges vertically 

 from the upper half of the subtropical belt, or lower in cloud-forested 

 pockets, to the upper limit of the lower montane belt. 



"This ovenbird is strictly arboreal, usually keeping well above the 

 ground in forest, along its borders, or at breaks in the mountain 

 terrain. I have seen it, as a rule, singly, the only one of its kind in a 

 traveling mixed flock ; I have one observation of an individual forag- 

 ing alone. An action bird, it searches limbs energetically. . . . Oc- 

 casionally I heard it make single-note cries." 



The nest of the species Philydor rufus does not appear to have 

 been described, nor have I seen an account of the nesting of the race 

 found in Panama. Schonwetter (Handb. Ool., Lief. 14, 1967, p. 31)
