latter place by Mr. Belding on May 17, 1882. To the north of La Paz Mr. 

 Bryant considers the bird rare. He saw it "on a few occasions along the 

 estero " north of Magdalena Bay, and at San Juan and Comondu. Mr. An- 

 thony, however, found it " very common all along the coast from El Rosario 

 north." He thinks that it nests at San Ramon, for it was seen there all sum- 

 mer. ^ It probably breeds in or near the Cape Region, also, but this remains to 

 be definitely ascertained. Up to within a few years it was common along the 

 coast of southern California, and it is said to breed at least as far north as 

 Oregon. Southward it is distributed throughout Mexico, Central America, 

 and many parts of South America to Chili and Buenos Ayres.

Mr. Belding found this Heron common in the Cape Region in the winter and 

 spring of 1881-82, but he states that it was rare at San Jose del Cabo on May 

 17, 1882. He emphasizes the fact that none were seen in white plumage. Mr. 

 Frazar met with it at both La Paz and San Jose del Cabo, but not commonly at 

 either place. His single specimen (No. 18,146, 9i La Paz, January 11) is a 

 '■ red " bird. 



Mr. Bryant gives the Reddish Egret as " tolerably common at Santa Mar- 

 garita Island, which was probably a night roosting place for many amongst the 

 mangroves. Ten were seen in one flock on February 14, 1888." Mr. An- 

 thony states that the species is " not uncommon at San Quintin." ^ 



The locality last mentioned is apparently the most northern one on the 

 Pacific coast from which the bird has been reported. To the southward it is 

 found in Mexico, Guatemala, and northern South America.

^Ir. Belding records the Louisiana Heron as less common at La Paz than the 

 Reddish Egret, and " rare " at San Jose del Cabo on May 17, 1882. Mr.
