The Black-Capped Petrel, (Aestrelata hasitata). —This species is already recorded in the A.O.U. "Check list" as extinct; but it appears that this may not as yet be absolutely true. On January 1, 1912, a strange thing happened. A much battered and exhausted black-capped petrel was picked up alive in Central Park, New York, taken to the menagerie, and kept there during the few days that it survived. When it died it was sent to the American Museum; and this may easily prove to be the last living record for that species. In reality, this species might as well be listed with those totally extinct. Formerly it ranged from the Antilles to Ohio and Ontario, and the causes of its blotting out are not yet definitely known.
This ocean-going bird once had a wide range overseas in the temperate areas of the North Atlantic. It is recorded from Ulster County, New York, New Hampshire, Kentucky, Ohio, Virginia and Florida. It was about of the size of the common tern.
The California Condor, (Gymnogyps californianus). —I feel that the existence of this species hangs on a very slender thread. This is due to its alarmingly small range, the insignificant number of individuals now living, the openness of the species to attack, and the danger of its extinction by poison. Originally this remarkable bird,—the largest North American bird of prey,—ranged as far northward as the Columbia River, and southward for an unknown distance. Now its range is reduced to seven counties in southern California, although it is said to extend from Monterey Bay to Lower California, and eastward to Arizona.
Regarding the present status and the future of this bird, I have been greatly disturbed in mind. When a unique and zoologically important species becomes reduced in its geographic range to a small section of a single state, it seems to me quite time for alarm. For some time I have counted this bird as one of those threatened with early extermination, and as I think with good reason. In view of the swift calamities that now seem able to fall on species like thunderbolts out of clear skies, and wipe them off the earth even before we know that such a fate is [ ] impending, no species of seven-county distribution is safe. Any species that is limited to a few counties of a single state is liable to be wiped out in five years, by poison, or traps, or lack of food.

On order to obtain the best and also the most conservative information regarding this species, I appealed to the Curator of the Museum of Vertebrate Zoology, of the University of California. Although written in the mountain wilds, I promptly received the valuable contribution that appears below. As a clear, precise and conservative survey of an important species, it is really a model document.
