March, 1898. Birds of the Pacific Slope of Los Angeles County. 49 



280 — TSSa. Cistothorus palustris paludicola Baird. 



Tule Wren. 

 Common resident of swampy regions in the lowlands. In fall and 

 winter it appears in localities where not found at other seasons, and 

 haunts weed-patches and rank grass. Breeds in the tule swamps prin- 

 cipally in May. H. Leland found nests with young nearly two-thirds 

 grown at El Monte by April 25 ('97). W. B. Judson took a set of 5 

 fresh eggs near Santa Monica, May 30 ('95). This last is our latest 

 nesting date, though eggs are probably laid much later. 



281 — ^260. Certhia familiaris occidentalis Ridgw. 



Californian Creeper. 

 Common resident of the coniferous forests on the mountains. It 

 is observed from 3000 feet up to 8500 feet. Juveniles appear by the 

 middle of July. W. B. Judson found a nest on Mt. Wilson, containing 

 3 fresh eggs, on May 29 ('97). 



282 — '/2'/a. Sitta carolinensis aculeata (Cass.). 



Slerjder-billed l^uthatch. 

 Common resident of the coniferous forests on the mountains; usu- 

 ally found above 4000 feet, but F. S. Daggett took a specimen in the 

 oaks south of Pasadena, Aug. 26, ('96). I took juveniles in the vicin- 

 ity of Mt. Waterman by July 15 ('97). 



283— 72<?. Sitta canadensis Linn. 



Red-breasted NutbatcF^. 

 Irregular visitant in the mountains above 4000 feet. Occurs 

 mostly in winter, but I found it on Mt. Wilson as late as May 9 ('96), 

 and H. A. Gaylord noted it again on Barley Flats, by Sept. 11 ('95). 



284 — 730. Sitta pygmcBa Vig. 



PygiT^y Nutbatch. 



Common resident of the coniferous forests on the higher mount- 

 ains. It is abundant on Pine Flats, and I took full-grown juveniles 

 there as early as July 2 ('97). 



285 — 733. Parus inornatus Gamb. 



Plain Titmouse. 

 Common resident in the coniferous regions from the lower country 

 up to 6000 feet on the mountain sides. Breeds mainly in April. I 

 took a set of nine fresh eggs near Pasadena, April 13 ('96), and a set 

 of six slightly incubated eggs in the same locality. May 12 ('94). 

 These probably indicate the extent of the breeding season. 



286 — 738. Parus gambeli'RA&gw . 



Mountain Chickadee. 

 Common resident in the coniferous forests on the mountains. Oc- 

 casionally, in severe winters, a few descend to the oak regions out on 

 the mesas, but they generally remain above 4000 feet. Full-grown 

 young appear by the first of July, so that nesting probably takes place 

 about the middle or last of May.
