50 WATER BIRDS 



when the half-grown Cormorant sits shrugged up into 

 a discouraged-looking bunch, or lolls listlessly against 

 his fellow nestlings. Around (and beneath the nest if 

 in a tree) are bits of fish and other debris, showing that 

 the supply often exceeds the demand.

This is the most common cormorant of the California 

 coast, and may be distinguished by its stiff white feathers 

 on sides of neck and by its blue gular sac. Rookeries 

 are found on seal rocks near Cypress Point, Monterey, at 

 Santa Cruz, and on the Farallones. These birds nest in 

 colonies on the steepest crags and ledges of those islands. 

 About the middle of May they may be seen carrying sea- 

 weed and kelp to their chosen site. There they fashion a 

 hew shallow, bowl-shaped nest, which becomes cemented 

 with guano ; or perhaps they redecorate an old one
