Resident. Fairly common in the highlands of Chiriqui and Vera- 

 guas above 1500 m. Ridgely {in litt.) once found this species at 

 Fortuna (1000 m), Chiriqui. I found a pair at Cerro Punta (2250 m), 

 Chiriqui. It has been collected in Chiriqui at Cerro Punta, Volcan de 

 Chiriqui, Boquete, and Santa Clara and in Veraguas by Arce at Calobre 

 and Calovevora (Salvin and Godman, Biol. Centr.-Amer., Aves, vol. 1 

 (pt. 27), 1883, p. 295) . This race also occurs in Costa Rica, and others 

 are found north to Mexico and from Colombia to central Bolivia.
