PARULA PITIAYUMI NANA (Griscom) 



Compsothlypis pitiayumi nana Griscom, 1927, Amer. Mus. Novit, no. 282, p. 8. 

 (Cape Garachine, eastern Panama [ = Darien].) 



Characters. — Smaller than P. p. speciosa; sides of face same color 

 as crown, lighter than in P. p. speciosa.; two white wing bars formed 

 by tipping on middle and greater wing coverts. 



Measurements. — Male (1 from Darien), wing 49.0, tail 36.8, oil- 

 men from base 10.6, tarsus 15.0 mm. 



Female (1 from Darien, the type), wing 47.2, tail 31.7, oilmen 

 from base 10.4, tarsus 14.2 mm. 



Resident. Local, but in some areas common in the lowlands and 

 lower foothills of eastern Province of Panama ("hills just east of 

 Chepo, on road from Platanares to Jesus Maria, eastward; common 

 in Bayano River valley" (Ridgely, 1976, p. 292) and in Darien, where 

 it is known from Garachine, the type locality, and from Cana, where 

 R. R. Benson collected a "breeding" female in the spring or summer of 

 1928 (Griscom, Bull. Mus. Comp. Zool, vol. 69, 1929, p. 183). Gris- 

 com (Bull. Mus. Comp. Zool., vol. 78, 1935, p. 367) assigned this race 

 to the "Arid Tropical Zone," although Cana is in fact humid. Nothing 

 is recorded of its breeding in Panama or in northwest Colombia, where 

 it also occurs. In mid- January 1975 Ridgely twice observed pairs feed- 

 ing fledged young on middle slopes of Cerro Quia (500-670 m). 

 Ridgely also found this species at Cana, where they were uncommon, 

 but has not seen it in the lowlands of Darien. 



The birds from the Bayano River basin have been assumed to be 

 nana, although specimens have not been collected.
