YELLOW-CROWNED NIGHT HERON. 
203. Nyctanassa violacea. 23 inches. 
The head of this species is adorned with three long, rounded 
white plumes; in life these plumes are rarely separated, but 
are nested together so that they appear to be as one. On the 
back they also have long lanceolate gray plumes; crown and a 
comet shaped patch under the eye of a yellowish white. As 
dusk approaches, these birds start out from their roosting 
places, and, with slow, measured flaps, wing their way to their 
feeding grounds, which are fresh water bogs, their food consist¬ 
ing of insects, frogs, snails and small fish.
