60 THE CONDOR VoL XIX
ton Street, June 6, 1916. The former nest contained two young, the latter four. This owl also breeds at the Stadium in Golden Gate Park.
24. Speotyto cunicularia hypogaea. Burrowing Owl. One was captured at Forty- third Avenue and Fulton Street, February 26, 1916. Birds of this species were noted by De Groot in the vicinity of Visitacion Valley, February 24, 1915 (Ray, Condor, xviII, p. 224).
25. Ceryle alcyon caurina. Western Belted Kingfisher. Sparingly resident at Lake Merced. Holes found in cliffs there were evidently made by this species.
26. Colapres cafer collaris. Red-shafted Flicker. Nest found at the buffalo pad- docks in Golden Gate Park, May 14, 1916. Not very common.
27. Calypte anna. Anna Hummingbird. Abundant. Many nesting records.
28. $elasphorus alleni, Allen Hummingbird. Common; many nesting records.
29. $ayornis ni?gricans. Black Phoebe. Nests about buildings'in the western part of Golden Gate Park, and probably at other places in the county.
30. Nuttallornis borealis. Olive-sided Flycatcher. Not common. Seen through- out the past summer in Golden Gate Park and in Sutro Forest. Nesting probable.
31. Empidonax difficilis difficilis. Western Flycatcher. Not an uncommon bird in Golden Gate Park and at Lake Merced, but nests not often found. Only a few nest- ing records.
32. Otocoris alpestris actia. California Horned Lark. Rather common resident on Twin Peaks, near Ingleside, in the Presidio, and on Bernal Heights.
33. Aphelocoma californica californica. California Jay. Common in Laurel Hill Cemetery; rather rare elsewhere in the county.
34. Agelaius phoeniceus californicus. Bicolored Blackbird. Nesting colonies were found at North Lake in Golden Gate Park, near Ingleside Beach, and on the east- ern tip of the northern portion of Lake Merced.
35. $turnella neglecta. Western Meadowlark. Rather common in the south- western part of the county, also found in the Richmond District.
36. Euphagus cyanocephalus. Brewer Blackbird. Nesting colonies numerous in Golden Gate Park, also on Sutro Heights, and near the South Side Life Saving Station.
37. Carpodacus purpureus californicus. California Purple Finch. Rather com- mon in Golden Gate Park and in Sutro Forest. Several nesting records.
38. Carpodacus mexicanus frontalis. California Linnet. Very common; nests abundantly.
39. Astragalinus tristis salicamans. Willow Goldfinch. Nests in willows near water; several nesting records from Lake Merced.
40. Astragalinus psaltria hesperophilus. Green-backed Goldfinch. Common; nests in larger trees than the preceding.
41. Astragalinus lawrencei. Lawrence Goldfinch. Not common, but seen often enough in the breeding season to make the nesting of the species in the county highly probable.
42. Spinus pinus pinus. Pine Siskin. Not uncommon, in the park, Sutro Forest and in the Presidio. Several nesting records.
43. Passer domesticus. English Sparrow. Most numerous bird in the county.
44. Passerculus sandwichensis bryanti. Bryant Marsh Sparrow. Breeds on the Islais Marshes; young seen there June 7, 1916. Birds apparently of this same subspe- cies, but averaging somewhat lighter in color, are resident at the Ingleside Golf Links, in the Presidio, and high up the slopes of Twin Peaks. If these are bryanti their oc- currence so far from their usual habitat on the salicornia marshes is rather puzzling.
45. Zonotrichia leucophrys nuttalli. Nuttall Sparrow. The most abundant native bird in the county.
46. dunco oreganus, subsp? (Sierra Junco or Point Pinos Junco). The sub-spe- cific standing of the juncos breeding in San Francisco County has not yet been determ- ined. From the nearness of the range of the Point Pinos Junco we might expect the San Francisco birds to be of that subspecies. On the other hand the Juncos found near Palo Alto and those recently discovered nesting in Berkeley were Sierra Juncos. It is possible that both subspecies will yet be found in the county. We have noted numerous young the past two years both in the Park and in Sutro Forest. We have also seen them about Lake Merced.
