teristic species of the count}', and in the districts sparsely wooded or covered 
with lupine bushes it is frequently the only bird met with. A very common bird 
thruout the Park and Presidio Reservation, and strays also to the public squares 
and larger gardens in the vicinity. Nests are placed in lupine bushes or low situa- 
tions in scrub oaks or pines altlio occasionally as high as 30 feet up and sometimes 
on the ground. I have noted fresh eggs from April 1 to July 24. The percentage 
of infertile eggs runs very high. Eggs show great variation in size and color, 
some specimens being finely and thickly dotted and others heavily blotched with 
chocolate or light brown, obscuring the ground color, while another type is pale 
greenisli-blue more or less heavily spotted and blotched with liver-brown fre- 
quently in the form of a circle around the larger end. 
29. Melospiza cinerea santaecrucis. Santa Cruz Song Sparrow. A common 
resident in the western half of the county especially about the fresh water ponds 
and lakes. I have also seen it at times in public squares in the heart of the city. 
Nests on the ground or in bushes a few feet up. 
30. Melospiza pusillula. Salt Marsh Song Sparrow. Found sparingly in the 
marshy tracts in the southeastern corner of the county along the bay shore. 
31. Pipilo maculatus falcifer. San Francisco Towhee. Common resident; 
nests in low bushes, scrub oaks or willows, or among overhanging blackberry 
vines. I have never found a nest placed on the ground, except once. 
32. Zamelodia melanocephala. Black-headed Grosbeak. Scarce at all 
seasons; no nesting record. 
33. Hirundo erythrogastra. Barn Swallow. 
34. Petrochelidon lunifrons. Cliff Swallow. Both observed during the breed- 
ing season but the nesting of either within the county is questionable. 
35. Lanius ludovicianus gambeli. California Shrike. But very seldom seen; 
no nesting record. Several times during the fall I have noticed it on the city 
streets. 
36. Vireo gilvus swainsoni. Western Warbling Vireo. Noticed during the 
summer; no nesting record. 
37. Dendroica aestiva brewsteri. California Yellow Warbler. Common 
summer resident, nesting usually in willows in the vicinity of water. 
38. Wilsonia pusilla chryseola. Golden Pileolated Warbler. Summer resi- 
dent, not numerous; no nesting record. 
39. Troglodytes aedon parkmani. Parkman Wren. Rather scarce summer 
resident; no nesting record. 
40. Baeolophus inornatus. Plain Titmouse. Rare; I found a single nest of 
this species in a tin can lodged in a pine tree, in May, 1892. It contained six 
eggs. 
41. Chamaea fasciata intermedia. Intermediate Wren-tit. A not abundant 
resident; more frequently heard than seen. No nesting record. 
42. Psaltriparus minimus minimus. California Bush tit. A very common 
resident, nesting abundantly in scrub oaks and gum trees of the park and else- 
where. I have found completed nests as early as February 22, and fresh eggs the 
first week of March. 
43. Hylocichla ustulata ustulata. Russet-backed Thrush. A common sum- 
mer resident, principally in the park; several nesting records. 
44. Sialia mexicana occidentalis. Western Bluebird. I have noticed but a 
single pair of these birds, and these, strange to say, were occupying a bird box on 
a pole in the yard of a residence in a thickly populated section known as “The 
Mission,” March 1903.
