FAMILY TITRAUPIDAE 



439 



Resident. Common on Isla Coiba, Veraguas, on the southern side 

 of Bahia Damas near Salinas and Maria, and casual elsewhere on the 

 island during my visit in 1956. ]n April 1976, Ridgely (in litt.) found 

 this species widespread on the island. 



In accordance with their usual habits, I often saw these tanagers fly- 

 ing for considerable distances across the high forest crown, or over the 

 clearings. One was seen on Isla Rancheria February 4. They are birds 

 of such strong flight that I would have expected that they might regu- 

 larly cross to the distant mainland, so it was a great surprise to deter- 

 mine that they represented a distinct subspecies.

Resident. The Palm Tanager is common in gardens, shrubby areas, 

 and woodland and forest borders throughout the lowlands of both 

 slopes, except in the drier regions of the Pacific lowlands from southern 

 Veraguas to western Province of Panama, where it is absent. In Chiri- 

 qui, it has been found as high as 1350 m, where Frank Hartman col- 

 lected a male at El Volcan on February 18, 1949. In April 1976, Ridgely 

 (in litt.) regularly saw this species around the houses of the Campa- 

 mento Central on Coiba Island, where it had not been reported previ-
