Obviously most of these birds were not breeding. 
While these birds were being banded a great amount of variance was 
noted in the distribution of black about the face and eye. Also there was 
variation in the coloration of the back, but this is attributed to the new 
plumage being darker. However, the variance in the face pattern was photo¬ 
graphed for later comparison with skins. It is possible that this variance 
is normal, but may indicate mixing of populations of the two subspecies 
that are present in this area. 
Accipiter sp. 
On 2 May as we were concluding the Fur Seal survey along the east 
coast, a large accipiterine hawk was seen soaring over the cliffs several 
hundred feet above. The light was from the west so the bird presented 
only a silhouette. The size of the bird suggests that it may have been a 
Cooper Hawk, but the nature of the sighting does not constitute a record. 
Tringa sp. 
During the Fur Seal survey along the east coast of Guadalupe Island 
a "small" shorebird was flushed. At the time I noted the bent-winged 
flight of the bird and size. Again, the nature of this sighting would not 
constitute a record. 
Wandering Tattler Heteroscelus incanum 
This shorebird was found in low density during the work on Guadalupe. 
They are found singly along stretches of rocky coastline. Dr. Hubbs states 
that they have been present on all visits at all seasons ol the year. 
Burrowing Owl Speotyto cunicularia 
The sighting of this bird is discussed under the account oi Oceanodroma 
leucorhoa which is presently its prey species. 
White-throated Swift Aeronautes saxatalis 
One bird was seen on Islote Negro on 27 April. 
Anna Hummingbird Calypte anna 
This bird reportedly came with the recent introduction of the wild 
tobacco. This seems to be its primary food source. There is however an 
endemic tobacco on the island.
