divided from other highlands by the broad valley of the Rio Tuira. The 

 Cerro Mali birds are very faintly darker buff on the lower breast and 

 abdomen.

Resident. Fairly common, but very local, in the foothills of Chiri- 

 qui, Veraguas on both slopes, and in eastern Province of Panama. Arce 

 collected it in 1869 and 1870 in Veraguas on the Cordillera del Chucu 

 and at Calobre. Elsewhere in Veraguas, J. H. Batty collected 2 females 

 in 1901 at Chitra, and in 1926 Benson and Gaffney took a male and fe- 

 male on the Rio Calovevora, on the Caribbean slope, at 300 and 450 m, 

 respectively. On January 4, 1974, Robert Ridgely, with R. Hinds, F. G. 

 Stiles, and J. D. Ridgely, found at least 25 on the road above Santa Fe 

 to the Continental Divide (870 m) . In Chiriqui, it is known only from 

 the Fortuna Dam site (900-1100 m) on the Rio Chiriqui east of Bo- 

 quete. Here Ridgely (in litt.) saw several in late February and early 

 March 1976. A male taken there February 29, 1976, is now in the 

 Gorgas Memorial Laboratory collection. Ridgely noted that it was quite 

 common rather far out along the road to the Divide; none were seen 

 close to Alto de Piedra or on the Cerro Tute ridge trail. The birds 

 were usually in small groups or pairs, generally with flocks of other 

 tanagers, usually rather high. They gave a distinctive loud, sharp tseeee, 

 teh-teh-teh; sometimes only one teh was given, other times up to four. 



In eastern Province of Panama, the Blue-and-gold Tanager has been 

 seen in the Cerro Jefe area (Ridgely, 1976, p. 319). The racial status
