598 BIRDS OF THE REPUBLIC OF PANAMA — PART 3 



Measurements. — Males (10 from Mexico, Guatemala, Nicaragua, 

 and eastern Costa Rica), wing 66.1-72.5 (68.6), tail 46.9-55.9 

 (52.7), culmen from base 13.3-15.7 (14.4), tarsus 16.0-17.9 

 (16.8) mm. 



Females (10 from Guatemala, Nicaragua, eastern Costa Rica, 

 and Bocas del Toro). wing 58.0-61.5 (59.5), tail 42.0-46.7 (44.1), 

 culmen from base 12.6-14.5 (13.7), tarsus 14.3-16.8 (15.2) mm. 



Resident. Found locally in small number in western Bocas del 

 Toro (Changuinola to Guabo). 



This race was first reported from Panama by Griscom (Amer. 

 Mus. Nov., no. 293, January 12, 1928, p.l) from specimens taken by 

 Benson in 1927 at Almirante. From April 7, 1927, to October 18, 

 1928, Hasso von Wedel collected four males and a female at Chan- 

 guinola, Almirante. and Guabo. In 1958 I secured three females 

 near Almirante. The first on January 20, was taken in rather dense 

 second growth on a steep hill slope above Water Valley. On January 

 29 I found another in the swampy woodlands at Pondsock Point, 

 and on February 10 the third in the woodland along Quebrada 

 Nigua. From the records indicated it is probable that the birds 

 range from the eastern shores of the Laguna de Chiriqui west to 

 the Costa Rican boundary, possibly farther east in eastern Bocas 

 del Toro. 



Beyond Panama this race ranges through the Caribbean slope of 

 Costa Rica, and beyond through Central America to eastern Mexico. 

 In Costa Rica, Slud recorded the display when "it may continually 

 flick a single wing."
