46 BIRDS OF THE REPUBLIC OF PANAMA PART 3 



A male, taken near Puerto Armuelles, Chiriqui, February 24, 

 1966, had the iris dark brown ; base of maxilla below nostril and 

 mandibular rami dull neutral gray; rest of maxilla dull brown, chang- 

 ing to fuscous on the base of the culmen ; rest of mandible pale dull 

 brown, slightly darker at tip ; tarsus and toes bluish slate ; claws dull 

 black. 



Measurements. — Males (10 from Costa Rica, Bocas del Toro, and 

 Chiriqui), wing 90.5-97.8 (93.3), tail 74.5-85.1 (78.9), culmen from 

 base 28.7-31.5 (29.9), tarsus 19.0-19.9 (19.4) mm. 



Females (10 from Costa Rica, Bocas del Toro, and Chiriqui), wing 

 85.3-97.8 (90.7). tail 71.8-80.4 (76.3), culmen from base 27.9-31.0 

 (29.3), tarsus 18.2-19.8 (19.2) mm. 



Resident. Fairly common ; on the Pacific slope from the boundary 

 with Costa Rica to eastern Chiriqui; to 1250 meters on Volcan 

 Baru ; on the Caribbean side in western Bocas del Toro. 



From available records, this race seems never to have been 

 abundant in Panama. The earliest report is by Sclater (Proc. Zool. 

 Soc. London, 1856, p. 140) who received one from Bridges taken 

 near "the town of David on the large forest-trees." Arce sent speci- 

 mens to Salvin (idem, 1870, p. 193) from Mina de Chorcha and 

 Bugaba. W. W. Brown, Jr., collecting for Outram Bangs, secured 

 six near David and Divala from October to December 1900, and 

 one near Boquete in April 1901. A small series in the California 

 Academy of Sciences was collected by Mrs. M. E. Davidson from 

 1929 to 1930 near Concepcion and El Banco, and in December 1931 

 and January 1932 near San Felix and Cerro Chame. There are two 

 in the American Museum of Xatural History from Cerro Flores in 

 eastern Chiriqui. 



Through extensive clearing for agriculture, available cover has 

 greatly decreased in these areas. In February 1956 I found scattered 

 individuals along the Rio San Felix and in the borders of mangroves 

 near the coast at Las Lajas. In March 1960 I encountered single 

 individuals in the scattered tree growth below Alanje, and on Febru- 

 ary 24, 1966, found one male near Puerto Armuelles. We have also 

 a male, presented by Dr. Frank Hartman, collected near El Volcan, 

 February 28, 1951. I have found no basis for the inclusion of 

 Veraguas in the range given by Griscom (Bull. Mus. Comp. Zool., 

 vol.78. 1935. p. 342). 



On the Caribbean side, L. s. compressus has been found rather 

 regularly near Almirante and Changuinola, where I noted a few in
