General Distribution. A non-migratory species resident in 

 western Mexico and Lower California north to Magdalena Bay. 



The Bird and its Haunts. The observations of Belding 1 , Bryant 2 , 

 and Frazar 3 show that in Lower California this Pacific Coast form 

 is found only in the red mangroves (Rhizophora mangle) and it is, 

 consequently, of local distribution. 



Belding records it from La Paz, Pichalinque Bay and Espiritu 

 Island where he considered it resident. At La Paz he found it to be 

 common, but in March, 1889, Frazar could secure only eight specimens 

 there. Bryant observed it in Magdalena Bay and on Santa Mar- 

 garita Island.
