550 BIRDS OF THE REPUBLIC OF PANAMA PART 2 



One of the three stomachs that I examined in detail held remains of 

 many ants of three distinct species. The second had skins of several 

 caterpillars, bits of ants, an orthopteran egg case, a number of beetles 

 of several kinds, and a few seeds. The other had the thin-walled 

 stomach packed with a dozen seeds of a Heliconia, each in shape like 

 a kernel of corn. 



The salivary glands in this species are large, extending the full 

 length of the lower jaw, with the sticky secretion abundant. The 

 tongue tip is longer and more flexible than tliat of species of Campe- 

 phihis of similar size. 



Belcher and Smooker (Ibis, 1936, p. 798) describe the eggs of the 

 somewhat larger typical race, Dryocopus lineatus [meatus, on Trinidad 

 as "pointed ovals, with the shell pure white, close-grained and highly 

 glossy." One set of 3 eggs measured on average 33.5-34.3x25- 

 25.8 mm. Another set of 2 were 34.5-34.8 X 26.0 mm. 



This race beyond Panama has a broad range across northern 

 Colombia to northwestern Venezuela. It is probable that in western 

 Chiriqui it continues into adjacent southeastern Costa Rica, as on the 

 Burica Peninsula, divided between the two Republics by a low, central 

 ridge of hills, I collected specimens of nuperus on the head of the Rio 

 Corotu part way up the hillside on the Panamanian side of the 

 boundary.
