482 BIRDS OF THE REPUBLIC OF PANAMA PART 2 



extend from March to July, with the main activity in April and May. 

 Several nests that he examined were placed in short, straight burrows 

 dug in slightly sloping ground on the forest floor, with an enlarged 

 nesting chamber at the end. Of 6 nests examined, 1 held 3 nestlings, 

 the others 2 young, or 2 eggs. The eggs are plain white "short and 

 blunt, with little difference in shape at the two ends." One measured 

 27.8 X 21.8 mm. Incubation is divided between male and female. The 

 young were completely naked when hatched. In or near the Canal 

 Zone, Arbib and Loetscher (Auk, 1935, p. 327) recorded breeding 

 in July and August. 



According to Salvin and Godman (Biol. Centr.-Amer., Aves, vol. 

 2, March, 1896, pp. 516-517) Lafresnaye named the typical form 

 from specimens "obtained at Panama by Delattre" which would 

 appear to place the type locality in central Panama. The subspecies 

 panamcnsis extends to the north and west along the Pacific slope 

 of Costa Rica. At the other end of the range it is found in Colombia 

 in extreme northeastern Choco at Unguia and Acandi. 



An egg of the closely allied race Malacoptila panamcnsis magdalenae 

 collected at El Real, Antioquia, Colombia, March 9, 1948, by M. A. 

 Carriker, Jr., is white with distinct gloss. It is elliptical in form and 

 measures 28.2x22.5 mm. The male flushed from the nest and was 

 taken for a specimen.
