Judging from their calls, attilas were fairly common, both in the 
swampy areas at the mouth of the Rio Catival, and in the high forest 
inland, but as usual the birds remained hidden. They were less vocif- 
erous than is common, and after calling once or twice ordinarily they 
became quiet so that some time lapsed before I was able to collect 
one. On January 22 Vicente and I located one somewhere among 
fairly low branches and after half an hour of intensive scrutiny of 
the tree, leaf by leaf and twig by twig, Vicente’s keen eye detected 
a slight movement, and with binoculars I could make out the side of 
the head and part of the bill of the bird through an opening in the 
screen of leaves. This was a male nearly in breeding condition, and 
the only one taken. Though we spent much time in looking we saw 
no others. Some of the men who worked in the edge of the forest 
were familiar with the excited calls of these birds, but were uncertain 
as to their source. 
The one taken is in greenish phase, with only slight indication of 
brown on the lower back and tertials, and the fore crown quite gray. 
The measurements are as follows: Wing 92.2, tail 71.0, culmen 
from base 28.1, tarsus 24.1 mm. In wing length it agrees with the 
form of Central America, being larger than A. s. sclateri of the 
eastern half of the Republic of Panama.

These cotingas were found in the higher branches of the forest 
trees, especially those with dead limbs, where they rested in the sun, 
or peered into cavities of various sizes. It is probable that they are 
more common than the few records that I made of their occurrence 
indicate, since they range regularly on or above the higher tree 
crowns, where they are hidden from below by the screen of leaves. 
Most of them were noted along the trails where the forest growth 
was more open. The two males and one female taken for specimens 
agree in color with skins from the western half of Panama. As
