BREWSTER : BIRDS OF THE CAPE REGION, LOWER CALIFORNIA. 53 



Frazar, however, found it common at both these places in 1887. Mr. Bryant 

 " saw two flying above the mangrove tops of the estero " north of Magdalena 

 Bay in March, 1888, and during the same month of the following year noted a 

 small flock rising " from the lagoon on Santa Margarita Island." This Heron, 

 as well as the Reddish Egret, probably breeds on or near the southern coasts 

 of the Peninsula, but is not positively known to do so. It has not as yet been 

 detected in California, but it occurs on the western coast of Mexico and 

 southward to Guatemala.

This race of the Green Heron, distinguished from A . virescetis hy its larger 

 size and deeper, richer coloring, was discovered in 1887 by Mr. Frazar, who 

 found it only at La Paz. His notes state that it frequented mangrove thickets 

 about the shores of the Bay, where it was "common " during February and 

 March, but as he mistook it for our eastern bird he preserved only two speci- 

 mens. It is probably the resident and characteristic form of this locality, 

 as well as of some of the neighboring islands, and it may range considerably 

 further to the northward along one or both coasts of the Peninsula, for Mr. 

 Bryant has reported seeing it in small numbers " at Santa Margarita Island 

 and along the estero, also at Comondu. No spechnens were secured," but Mr. 

 Bryant thinks that " a skin in the collection of the California Academy of 

 Sciences from Magdalena Bay, is probably referable to this form." All these 

 records require confirmation, however, for at the time they were made Mr. 

 Frazar's bird was the only Green Heron known to occur in Lower California.
