NO. 9 BIRDS OF ISLA COIBA, PANAMA—WETMORE 4I 
as in many mainland localities. Occasionally I heard them calling 
from the high forest crown, where they were hidden from view by 
the screen of leaves, or saw little groups in flight near the work 
camps. But it was not until the guayabo trees scattered through the 
pastures came into blossom that I recorded them regularly, as then 
they came in bands of a dozen to 25 to feed at the blossoms. Three 
that I shot for specimens on January 26 at one of these trees had the 
throat completely filled with nectar. 
Family CucuLipAE: Cuckoos, Anis 
CROTOPHAGA ANI Linnaeus: Smooth-billed Ani, Garrapatero Comin

maica. ) 
Anis in the usual little groups of 6 to 12 or so were found in the 
low thickets in abandoned fields, or around the borders of the pas- 
tures. They were restricted to the cleared areas, and, though only 
fairly common, probably were more abundant now that some of the 
land has been cleared than they were formerly when the island was 
completely forested. Two were taken for specimens January 21 
and 26. 
Family StriGIpDAE: Owls 
BUBO VIRGINIANUS MAYENSIS Nelson: Great Horned Owl, 
Gran Buho Cornudo

On February 4, on Isla Rancheria, I came on one of these birds 
resting in a large-limbed, open tree standing at the edge of a swamp. 
The bird was only a short distance from me, as at the time I was 
climbing along the face of a steep bank, high above the muddy, level 
ground. While I had a clear view of the owl for a minute or so, I 
failed to secure it for a specimen owing to one of those mishaps that 
torment the naturalist when a quick snap shot is necessary, since my 
footing on the slippery bank was treacherous. My disappointment 
was the greater since I knew at the moment that the only record of 
this species for Panama was that of a bird taken by Enrique Arcé 
at Chitra, Veraguas, in 1868. As the bird was near at hand I could 
see that it was quite dark in general coloration. 
From examination of available material, including that in the 
British Museum (Natural History), I agree with Griscom ™ that the
