58 BIRDS OF THE REPUBLIC OF PANAMA PART 2 



it has been found in Nicaragua, Costa Rica, northern and eastern 

 Colombia, and Venezuela. In view of the number taken at El Real it 

 should be noted that I did not find it there during work in early 1964. 

 Apparently this is a bird that disappears when its forest haunts are 

 invaded.
