ICTERUS CUCULLATUS CUCLLLATUS Swainson 



Swainson's Hooded Oriole 



Similar in its habits to Sennett's hooded oriole, this race is some- 

 what darker, more orange, less yellowish in the males, and notably 

 darker in the females. 



Swainson's hooded oriole ranges from western Texas south to 

 Guerrero and Veracruz, and its breeding range extends from western 

 Texas (Boquillas, Del Rio), Chihuahua (Sabinas), Nuevo Le6n 

 (Monterrey, Linares), and Tamaulipas (Gomez Farias); south to San 

 Luis Potosi (probably San Luis Potosi), northern Guerrero (Iguala), 

 and southern Veracruz (Orizaba, Catemaco). Its winter range is 

 uncertain; the northernmost winter specimens are from Morelos 

 (Cuernavaca) and central Veracruz (Mirador); in spring and fall 

 specimens have been taken in western Texas (Marathon, Langtry), 

 Nayarit (Santiago), Michoactin (Lake Patzcuaro, Tacambaro), central 

 Guerrero (Chilpancingo), and Veracruz (Puerto Mexico).
