Hab. Chatham Island (Darwin, Sundevall); James Island (Sundevall); Indefatigable, 
Bindloe, and Abingdon Islands (Hade/). 
“This Tyrant-bird was found on all the islands visited. It utters a feeble cry like 
that of the preceding species. It brings its mandibles together with an audible snap as 
they close upon its insect prey.”—H. 
Genus AsIo. 
Asio galapagensis is barely separable from the widely spread A. drachyotus, which 
extends not only over the greater part of the Old World, except Australia, but also is 
found in North America and as far south as the Falkland Islands. Asvo is also an 
inhabitant of the Sandwich Islands.

Hab. James Island (Darwin); Indefatigable Island (Habe/). 
Dr. Habel’s six specimens of this Owl agree closely with one another, and with the 
plate in the ‘Zoology of the Voyage of the Beagle.’ They confirm the differences 
pointed out by Mr. Darwin between it and the well-known Short-eared Owl, to which I 
have alluded above. This being the case, I think the species must stand under a distinct 
title, though these differences are but slight. 
Of this bird Dr. Habel writes:—“‘A common species on Indefatigable, but not 
observed by me either on Bindloe or Abingdon. I saw it on Hood’s Island. Specimens 
were covered with lice, which ran over my hands and arms as I took off the skins. 
Under the skin, near the throat, of a male I found twenty-six parasitic worms.”—H,
