Horned Grebe 163 



Horned Grebe. — Columbus aurilus. 13.50 



Rare Migrant 



Field marks. — Feathers of head black and light brown, and 

 stand out like a monk's cowl, giving the bird a bizarre 

 appearance; upper parts reddish-brown to blackish; white 

 patch on wing. 



If one can get close enough to this Grebe to observe its 

 strange head, identification will be easy, for there is no other 

 bird at all like it. 



Holbcell's Grebe. — Colymbus holballu. 19.00 

 A very much larger species, recorded here but once.
