152 BIRDS OF THE REPUBLIC OF PANAMA PART 3 



THAMNISTES ANABATINUS SATURATUS Ridgway 



Thamnistes anabatinus saturatus Ridgway, Proc. Biol. Soc. Washington, vol. 21, 

 October 20, 1908, p. 193. (Bonilla, Costa Rica.) 



Characters. — Olivaceous brown above, with crown closely similar 

 to back. 



Measurements. — Males (10 from Chiriqui and Costa Rica), wing 

 64.5-70.8 (67.2), tail 48.0-53.9 (51.1), culmen from base 19.0-21.3 

 (20.1), tarsus 19.5-20.8 (20.2) mm. 



Females (10 from Costa Rica and Nicaragua), wing 64.9-69.0 

 (66.7), tail 47.0-51.8 (49.2). culmen from base 19.1-21.4 (20.3), 

 tarsus 20.0-20.7 (20.2) mm. 



Resident. Rare, in the mountains of western Chiriqui and western 

 Bocas del Toro. 



The earliest record is that of Salvin (Proc. Zool. Soc. London, 

 1870, p. 194) who listed one taken by Arce at Bugaba, western 

 Chiriqui. Another report for Chiriqui is that of Dr. Frank A. Hart- 

 man who secured two near El Volcan, a male, now in the U.S. Na- 

 tional Museum, taken March 2, 1956, and a female collected March 9 

 in the same year. There are two reports from Bocas del Toro, near 

 the trail from Boquete to Chiriqui Grande. These include two males 

 collected in June 1901 by W. W. Brown, Jr., at 600 and 900 meters 

 (Bangs, Proc. New England Zool. Club, vol. 3, 1902, p. 41) and one 

 taken by H. von Wedel at 1060 meters March 27, 1928 (Peters, Bull. 

 Mus. Comp. Zool., vol. 71, 1931, p. 320). This race is better known 

 to the north in Costa Rica, and has been recorded in small number 

 through Nicaragua to Central Honduras. Beyond that point inter- 

 gradation comes with typical T. a. anabatinus which ranges north to 

 southern Mexico. 



In early April near El General in southwestern Costa Rica, Skutch 

 (Pac. Coast Avif., no. 35, 1969, pp. 198-200) found a pair building a 

 nest about 15 meters from the ground in a tree within the forest edge 

 bordering a pasture. "The completed structure was a vireo-like 

 cup . . . attached by its rim to the supporting twigs, and composed 

 largely of pieces of brown dead leaves, bound together and to the 

 support by cobweb." Because of the location the nest was inaccessible 

 so that the eggs were not seen. It was recorded that both parents 

 shared in incubation and in the care of the young. 



THAMNISTES ANABATINUS CORONATUS Nelson 



Thamnistes anabatinus coronatus Nelson, Smithsonian Misc. Coll., vol. 60, no. 3,

 Pirre, Darien, Panama.)
