March, i8gS. Birds of the Pacific Slope of Los Avgeles County. 15 



74 — 20IC. Ardea virescens anthoyiyi Meariis. 



Anthonys Greer) Heron. 



Common spring and fall migrant, appearing singlj' along streams 

 and ponds. It is not only found in the lowlands, but I have taken 

 specimens in the mountain canons back of Pasadena. Noted in the 

 vicinity of Pasadena in the fall of '94, from Aug. 21 to Sept. 22. 



75 — 202. Nyclicorax nycticorax ncevius (Bodd.). 



BlacK-crowned Nigbt Heron. 

 Abundant migrant and common throughout the winter. Found 

 along the margins of any body of water or stream, frequently at a con- 

 siderable elevation in the mountain canons. Although this bird has 

 not been found nesting within the limits of the County, it probably 

 does not go far, as I have shot specimens toward the latter part of April 

 which coutained well-developed eggs. 



76 — 206. Grus mexicana (Mull.). 



Sandhill Crane. 

 Principally in evidence during the migrations in large V-shaptd. 

 flocks high in the air, flying northward or southward according to the 

 season. A. M. Shields states that a few stay through the winter and 

 spring months up to Miy first, among the Centinela hills and grain- 

 fields. F. S. Daggett has noted them in grain- fields in winter near 

 Pasadena. 



77 — 210. Rallus obsoletus Ridgw. 



California Clapper Rail. 

 Tolerably cvnnon resident in the salt marshes along the coast. 

 Among the lagoons between San Pedro and Long Beach, their loud 

 cackling notes are frequently heard, especially at high tide, when they 

 are driven to the higher ground. They probably nest in moderate 

 abundance, though few eggs have so far been taken. W. B. Judson 

 took a set of six slightly incubated eggs at Ballona, May 16, '94. 



78 — 212. Rallus virginianus Linn. 



Virginia Rail. 

 Of not infrequent occurrence in spring and fall. A few have been 

 noted in summer, so they probably breed. 



79 — 214.. Porsana Carolina (Linn.). 



Sora. 

 Wherever there are swampy lands overgrown with marsh gra.ss 

 and tules, the Sora is a more or less common resident. During the 

 migration.'^ it is somewhat more numerous and appears in localities 

 where it is not found at any other .season. A. M. Shields writes me 

 that he has taken many sets, all in May. The nest is built usually on 

 the ground, and well concealed within a clump of grass or tules. Sets 

 are of 7 to 14 eggs. 



80 — 2j6. Porzana Jamaiceiisis (Gmel.). 



Black Rail. 

 This very small and secretive bird is but rarely noted. Evan
