504 BIRDS OF THE REPUBLIC OF PANAMA PART 4 



ary and March were molting, while most of those collected in April had 

 completed their molt. 



Eisenmann (in litt.) noted this species on short visits to El Rey and 

 Saboga islands on July 18 and 19, 1964. On Saboga several were sing- 

 ing a very high, thin dzit, sitee-sitee-sitee-sitee; the i in sitee was short, 

 as in "sit." 



COEREBA FLAVEOLA COLUMBIANA (Cabanis) 



Certhiola columbiana Cabanis, 1865, Journ. f. Ornith., 13, p. 412. ("Bogota," 

 Colombia. ) 



Characters. — Rump bright yellow, with yellow areas more extensive 

 than mexicana; back and wings dark, but slightly less so than in C. f. 



cerinoclunis. 



A male taken at the Candelaria Hydrographic Station, in the Prov- 

 ince of Panama, March 7, 1961, had the iris wood brown; base of gonys 

 and adjacent lower edge of mandibular rami dull wood brown; rest of 

 bill black; tarsus, toes, and claws dusky neutral gray. 



Measurements. — Males (10 from Veraguas, Los Santos, Herrera, 

 and the Canal Zone), wing 51.0-56.8 (53.8), tail 28.1-35.7 (31.5), oil- 

 men from base 12.1-14.0 (13.5), tarsus 14.9-18.4 (16.3) mm. 



Females (10 from Veraguas, Herrera, the Canal Zone, and San 

 Bias), wing 46.8-55.5 (50.4), tail 26.2-31.9 (29.0), culmen from base 

 11.8-13.7 (13.0), tarsus 14.4-16.6 (15.6) mm. 



Resident. Common in lowlands and foothills from mainland Vera- 

 guas eastward into Colombia and Venezuela. Found in gardens, clear- 

 ings, light woodland, and forest edges. Aldrich and Bole (Scient. Publ. 

 Cleveland Mus. Nat. Hist., vol. 7, 1937, p. 22) found it common about 

 cultivated coconut groves and houses on the shores of Montijo Bay in 

 Veraguas. Ridgely (1976, p. 287) calls it "absent or in very small num- 

 bers (possibly seasonal) in dry Pacific lowlands from eastern side of 

 Azuero Peninsula to Pacific side of Canal Zone and Panama city area." 

 Eisenmann (Smiths. Misc. Coll., vol. 117, no. 5, 1952, p. 49) lists nests 

 found at Barro Colorado Island in the Canal Zone from November to 

 April, and in August, suggesting that the Bananaquit breeds all through 

 the year, or nearly so. Skutch (Pac. Coast Avif. no. 31, 1954, pp. 404- 

 420) found eight nests on Barro Colorado Island between late Decem- 

 ber and early June. On January 26, 1957, I shot a juvenile barely 

 grown at Mandinga, San Bias, and on March 5, 1959, I collected an 

 immature at the mouth of the Rio Paya, Darien.
