26 THE CONDOR Vol. XVIII none from the Northeast. Of regular occurrence at Goose Lake and manifestly breed- ing (or trying to do so; the weather was very bad) in June, 1912. Podasocys rnontanus. Mountain Plover. Two coastwise appearances of stngle? birds on the Santa Barbara beach must also be reckoned as casual: October 19, 1912, and August 25, 1915. Parabuteo unicinctus harrisi. Harris Hawk. "Summer visitant to the valley of the lower Colorado River; two records for the California stde". Also wtnter "visitant" and probable resident in the same region. Mr. Brooks and I encountered these birds repeat- edly during our stay at Potholes in February, 1913 (records February 9, 10, 11, and 12). On the 12th I saw three at one time seated. They kept to the taller timber of the Laguna backwater, and we were unable to secure specimens, though on another occasion I did study one with binoculars from the foot of the tree in which he stood. Buteo swainsoni. Swainson Hawk. "Recorded north to Shasta Valley . . . east to. Independence Lake". A nest found June 11, 1912, in a yellow pine near Goose Lake was not.yet occupied, although in recent repair, with the birds in watchful attention. Suc- ceeding bad weather seemed to discourage the birds utterly, and no eggs had been laid at 'the time of our departure, June 29, although we frequently saw the hawks in the neighborhood. Birds also seen near the crest of Sugar Hill. Aquiia chrysaetos. Golden Eagle. "Rare or wanting east of the Sterran divide". Encountered in the Pit River Valley, in southern Alturas County, June 5, 1912; and sparingly in July along the crest of the southern Warners (July 2, 1912, near Eagle Peak; July 12). Faico mexicanus. Prairie Falcon. Dr. Grinnell correctly states the breeding range of this species as Sonoran, but it is perhaps worth while to note its habitual invasion of Boreal zones in summer. Dr. Fisher records the Prairie Falcon from Big Cottonwood Meadows (alt. c. 9800), and Whitney Meadows (alt. c. 9800) in August (Birds of the Death Valley Expedition, May, 1893, p. 40). We saw it repeatedly in late June and in early July in the Warner Mountains, and on the 5th of July, 1912, as we stood on the summit of Warren Peak, a Prairie Falcon passed slowly within fifty feet of us, then circled above us at an altitude of 10,000 feet (zonally equivalent to an altitude of 13,000 in the southern Sierras). As an extreme of the Pposing tendency I would instance the regular nesting of a pair of these birds on the southern or seaward slope of the Santa Ynez Range, near Santa Barbara. This pair hunts over the coastal lowlands, and I have caught them on three occasions on the crest of the sea cliff, and once over the ocean. Faico peregrinus anatum. Duck Hawk. This species is also a rare but regular breeder on the innermost coast ranges separating Kern and San Luis Obtspo counties. On the 6th of April, 1914, I took a set of four eggs of the Duck Hawk in western Kern County,.at least sixty miles distant from the ocean, in a bee line. Pandion haiiaetus caroiinensis. American Osprey. "Two definite nesting localities in the interior, Eagle Lake . . . Kaweah River". Is pretty certain also to nest on Goose Lake, where we saw a bird at close range, June 17, 1912. Glaucidium gnoma Grinneili. Coast Pygmy Owl. Either this form or one having plumage a thousandth part of a shade lighter occurs commonly enough in the Santa Ynez Range near Santa Barbara. I have a specimen, a male, taken by Mr. Allan Brooks in Los Canoes Canyon, January 2, 1913. Other record dates are December 27, 1910, January 11, 1913, and September 18, 1915. Yet of 1?. g. grinnelli Grinnell says, "occurs possibly south as far as Santa Margarita" (northern San Luts Obispo County); while of (?. ?. cal?forn?cum the nearest record station appears to be in the San Gabriel foothills of Los Angeles County. Chordeiles acutipennis texensis. Texas Nighthawk. "Common summer visitant". On the 31st of January, 1911, near Long Beach, I descried a Nighthawk which Mr. C. B. Linton promptly identified as the Texan. It was early dusk and the bird was under observation for several moments as it quartered the sky. It certainly was not a Poor- will. Chaetura vauxi. Vaux Swift. "Common summer visitant locally 'to the northwest humid coast Transition". The occurrence of Vaux Swifts at Kenawyers on the middle fork of the Kings River, July 9, 1913, would argue that there are also isolated breeding oolontes of these lesser swifts in the Sierras; and this the knowledge of their breeding habits in the Cascade Mountains would lead us to expect.
