462 BIRDS OF THE REPUBLIC OF PANAMA rART 2 



Females (10 from Chiriqui and Bocas del Toro), wing 79.1-83.4 

 (81.1), tail 93.1-98.5 (95.4), oilmen from base 47.5-53.6 (49.9), 

 tarsus 12.0-13.6 (12.7) mm. 



Resident. Local, in small number, in western Chiriqui, from sea 

 level near David to 1,350 meters on Cerro Pando ; found also in 

 western Bocas del Toro. 



The early definite records for this bird include specimens col- 

 lected near David by Bridges (Sclater, Proc. Zool. Soc. London, 

 1856, pp. 139-140), and, 12 years or more later, by Arce (Sclater, 

 idem, 1870, p. 201) from Mina de Chorcha, Bugaba, and the southern 

 slopes of Volcan de Chiriqui. W. W. Brown, Jr., (Bangs, Auk, 

 1901, p. 360) found them in some numbers near David and Divala 

 from October to December 1900, and at Bugaba in July 1901 (Bangs. 

 Proc. New England Zool. Club, vol. 3, 1902, p. 32). There is a 

 specimen in the California Academy of Sciences collected by Mrs. 

 Davidson, December 25, 1930, near El Banco at about 1,000 meters 

 elevation on the south slope of the volcano southwest of Boquetc. 

 Mina de Chorcha, east of David, is the most eastern point at which the 

 bird has been recorded in Chiriqui. 



In Bocas del Toro, Wedel secured a series at Guabo and Crica- 

 mola in 1928 (Peters, Bull. Mus. Comp. Zool., vol. 71, 1931, p. 317), 

 and there is a specimen in the Havemeyer collection in the Peabody 

 Museum at Yale taken at Almirante July 25, 1927, by Austin Paul 

 Smith. 



Skutch (Ibis, 1963, p. 354), in southwestern Costa Rica, found 

 that these jacamars disappear from their breeding stations with 

 cutting and other encroachment in their forest haunts, and apparently 

 the same factors have greatly reduced their abundance in Panama 

 within recent years. The only modern records for Bocas del Toro 

 are 2 from Almirante secured July 16, 1962, and February 7, 1964, 

 by personnel of the Gorgas Memorial Laboratory. On the Pacific 

 side Dr. F. A. Hartman secured 1 at 1,350 meters on the slopes of 

 Cerro Pando, beyond El Volcan, February 23, 1949. I have made 

 careful search for it in the area adjacent to Divala, where formerly 

 it was common, without success until 1966, when on February 17 I 

 found a few in a small tract of forest in the region known as Olivo, 

 about 10 kilometers northeast of Puerto Armuelles, and on February 

 25, 1 at Punta Balsa, near the southern end of the Burica Peninsula. 

 At Olivo I saw them resting quietly on open perches in undergrowth 

 in heavy shadow under tall forest trees. The specimen found at 

 Punta Balsa was in a similar area in a forested quebrada.
