Common resident. In regard to the status of the raven of the islands, I 
must confess to a feeling of uncertainty. Ridgway (28) identifies birds from 
Clemente and Catalina as C. c. clarionensis, stating that although not quite as 
small as the latter in its typical form, excepting the tarsus, they are nevertheless 
nearer to it than they are to the mainland birds. Clarionensis is similar to sinu- 
atus but smaller, especially the bill, and was deseribed from a single specimen 
(Rothschild & Hartert, Novit. Zool., 1x, 1902, p. 381.). The type may have been 
merely a particularly small specimen from the locality where it was secured. At 
any rate, all the island specimens examined average well below the measure- 
ments for sinuatus, as given by Ridgway (28). Three skins from my collection, 
compare with Rothschild’s type from Clarion Island, Mexico, as follows—

‘Middle toe without claw. 
On the Coronados there are at least two resident pairs, one breeding on the 
sandstone cliffs on south island, and the other on the west end of the same. On 
San Clemente, G. F. Breninger (14) remarks that during February, 1903, he saw 
thirty-eight at one time, and that there were ‘‘seven nests within a hundred 
yards’’. Although still decidedly common, they do not now occur there in such 
great numbers, for they are persistently poisoned by the sheepmen, who assert 
that they are in the habit of pecking out the eyes of very young lambs. They are 
quite common on San Nicolas Island. 
At Catalina there is always a flock of these birds in the vicinity of the garb- 
age dump near Avalon. -Many of them breed in the pockets of the nearby cliffs, 
but the birds are so wary that it is no easy matter to locate the nests. I have also 
found many old nests in trees in different parts of the island. In such a situa- 
tion C. H. Richardson (15) took a set of five fresh and one slightly addled ege, 
Mareh 19, 1905. 
Two or three pairs breed on the cliffs of Santa Barbara Island, where J. 
Grinnell (8) states that they evidently subsist on the eggs and young of the sea 
birds which nest so numerously in that locality. On Anacapa, HI. C. Burt (27) 
found a nest ready for eggs March 17, 1911, and is sure that there was only one
