52 NORTH AMERICAN HERONS AND THEIR ALLIES. 



The Louisiana heron breeds along the whole eastern coast of Mex- 

 ico and north on the west coast to Mazatlan, Sinaloa (Lawrence) ; 

 La Paz, Lower California (Belding) ; and Santa Margarita Island. 

 Lower California (Bryant). It breeds south throughout Central 

 America to the Rio Sabana, Panama (Salvador! and Festa) ; Don 

 Diego, Santa Marta, Colombia (Allen) ; the islands of Aruba and 

 Margarita, off the coast of Venezuela (Cory) ; and to Yaqueria in 

 northwestern Ecuador (Hellmayr). It is one of the commoner 

 herons in the Bahamas north to Berry Island (Cory) ; abundant in 

 Cuba (Gundlach) ; abundant in Jamaica (Field) ; and in Porto 

 Rico (Gundlach). 



The Louisiana heron is only partially migratory. While many of 

 the most northern breeding birds retire a short distance southward 

 in winter, a few remain at this season at Charleston, S. C. (Wayne) ; 

 Matamoras, Tamaulipas (Phillips) ; Mazatlan, Sinaloa (Lawrence) ; 

 and La Paz, Lower California (Belding). On the other hand, it is 

 stated that the birds do not winter in Louisiana (Beyer, Allison, and 

 Kopman) nor on the Texas coast, even as far south as Brownsville 

 (Merrill).

 Cuba from June to October (Gundlach) ; young a quarter grown at

The typical form, tricolor, is restricted to the Guianas and Brazil, 

 occurring in the latter country south to Cajutuba and Garape (Pel-
