Nycticorax nycticorax naevius (Boddaert) 

 Black-crowned Night Heron 

 Migrating night herons were observed on numerous occa- 

 sions on the east slope of San Gorgonio Pass, single birds being 

 noted at Snow Creek, Whitewater, and Cabezon, on dates rang- 

 ing from May 24 to June 3. Several seen at Hemet Lake early 

 in August were also probably transients. 



Butorides virescens anthonyi (Mearns) 

 Anthony Green Heron 

 Single birds, probably migrants, seen at Cabezon and White- 

 water, on May 16 and 30, respectively. Next observed, a solitary 

 individual, at Ilemet Lake. August 15. 



Fulica americana Gmelin 

 Coot 

 Seen only at Hemet Lake, where, during the first two weeks 

 in August, the species was fairly common at the marshy upper 

 end ui' the lake. 



Steganopus tricolor Vieillot 

 Wilson Phalarope 

 Three seen together at the east end of Hemet Lake, August 11. 

 One of these secured (no. 2946) is a female in Juvenal plumage, 

 with traces of first winter plumage appearing on the back. On 

 August 22 a large floek of phalaropes was observed far out on 

 the lake. From a distance they appeared to be too small for 

 this species, and may have been Lobipcs lobatus, but they could 

 not be approached near enough for positive identification. 



Recurvirostra americana Gmelin 



Avocet 



Encountered only at Hemet Lake. On August 8 a flock of 

 ten, and on August 21 several single birds were seen along the 

 shore at the upper end of the lake. The one specimen taken, an 

 adult female secured on Augusl 8 (no. 2942), is molting into 

 winter garb, the plumage of the head, neck and upper breast 

 being a mixture of gray and cinnamon colored feathers.
