 4 THE CONDOR ] Vol. II lvifauna of a !00-Acre ilanch. BY Iff. S. SWARTH, LOS [Read before the Southern Division of the Cooper Orn. Club.] The following notes were taken in a territory of about one hundred acres, situated in the north-western part of the city of Los Angeles, Cal., about a mile north-west of Westlake Park. Included in this land is a pond of about an acre in extent, which adds materially to the number of species recorded. The observa- tions extend over a period of about seven years. I PIED-BILLED GREBE. Podilymbusfiodicefis. Resident throughout the year, but most common during the fall and winter. In the spring of i895 a pair built a nest and laid their set, but the water rose arid forced them to desert. In the spring of I896 a pair laid their set and raised their brood successfully. 2 WESTERN GULL. Larus occidentalis. 3 AMERICAN HERRING GULL. Larus ar.entatus smilhsonianus. In the winter these two species are often seen flying over; they light occasionally but not often. 4 FARALLONE CORMORANT. Phalacrocorax dilophus albociliatus. Have occa- sionally lit in the pond, but as there are no fish in it, they never remain long. 5 RED-BREASTED MERGANSER. 32reranser serralor. On Dec. 27, 894, I shot a female of this species out of a flock of seven. On several other occasions I have seen single birds which I did not secure and which may have been either of the two other species of Merganser. 6 MALLARD. Anas boschas. 7 BALDPATE. Anas americana. 8 GREEN-WINGED TEAL. Anas carolinensis. These species drop in occasion- ally at any time between the first of October and the end of March. 9 BLUE-WINGED TEAL. Anas discors. Mr. W. B. Judson shot a female on Oct. 3 x, t896, but did not save it as a specimen. On Oct. 3, x898, I secured one, also a female, which I now have in my collection. xo CINNAMON TEAL. Arias cyanofitera. This species is seen more often than almost any of the others, and would undoubtedly breed if they were not dis- turbed. In the spring of 896 a pair renmined until very late and in all probabil- ity had part of their set laid, but as they were very tame they were shot by some wandering sportstnan, so-called. In the spring of r898 a pair remained and laid part of their set, but the nest was found and the eggs taken by some small boys. The birds then left. Cinnamon Teal occasionally drop in in July and August. x x SHOVELLEt. Xfialula clypeata. x2 PINTAIL. Dafila acuta. 3 REDHEAD. Aylhya americana. x 4 CANVASBACK. Aylhya vallisneria.. x5 LESSER SCAUP DUCK. Aythya affinis. These species are occasionally seen any time between the first of October and the end of March. x6 RING-NECKED DUCK. Aythya collaris. On October x 5 I saw a flock of one male and three females, all of which I secured. I have seen two or three others, single birds, but they do not drop in often. x 7 GOLDEN-EYE. Glaucionelta clanula americana. I have several times seen single birds, but never managed to shoot any. 18 BUFFLE-HEAD. Charitonetta albeola. Seen occasionally. x 9 RUDDY DUCK. Erismatura rubida. The Ruddy Ducks arrive earlier and stay later than any of the others, excepting the Cinnamon Teal. They become very tame if not molested and sometimes stay for weeks at a time. One year a flock of about a dozen remained nearly all winter. 20 AMERICAN WHITE-FRONTED GOOSE. Anser albifrons ambeli. On Feb. 3, x897, I flushed a White-fronted Goose out of some weeds at the edge of the lake. I was within fifty feet of it before I saw it, but had no means of shooting it. 2x FULVOUS TiEE DUCK. Dendrocynafulva. On April x8, x898, I saw a pair of this species. They were not very wild and I secured them both with very little trouble.
