I yS MRDS OF THE REPUBLIC OF PANAMA PART 2 



It seems certain that these owls are found also in the forests of the 

 Cerro Azul in the eastern sector of the Province of Panama, as I have 

 recorded them in the foothills of this range above the Rio Cangandi, 

 near Mandinga on the San Bias side. 



I have seen them during the day near Juan Mina in a palm tree 

 standing in heavy forest, and in the Darien jungle in dense stands of 

 bamboo. 



At Mandinga the Cuna Indians called them sit le pa. 



Belcher and Smooker (Ibis, 1936, p. 18) describe a set of 2 eggs of 

 this race, collected on the island of Trinidad, as "roundish ovals, dull 

 white, with slightly rough surface." The 2 eggs in another set were 

 "more regular ovals." The range of measurements is given as 38-40.6 

 X 31.5-32.5 mm. One set came from a tree nest that appeared to be 

 an old structure made by some other bird. The other was from a 

 hole in a tree. 



The population of Panama is at the northwestern extension of this 

 race, which ranges across Colombia and northern Venezuela to 

 Trinidad.
