178 ARDEIDZ. 
Colombia and Peru, is said by Stolzmann to be solitary and difficult to observe, being 
very shy and flying away at the sight of man; he found this bird up to an altitude 
of 5800 feet, and believes that it even ascends higher, if there are suitable fishing- 
srounds. It frequents the mountain-streams and feeds on small fish, but we have 
no record of its breeding.

This Tiger-Bittern is widely distributed in South America, and extends its range into 
the State of Panama. It is easily distinguished from 7. cabanisi by the line of feathers 
down the throat, the latter being bare only on the sides; the base of the lower 
mandible is also bare. . 
Scarcely any notes have been published on the habits of this species. Léotaud says 
that it is often to be seen in Trinidad among the rushes covering the marshy portions 
of the island, as well as in the mangroves on the edge of the swamps. The food is 
similar to that of the larger Herons, and the birds fish apparently by night, as on 
every occasion that Léotaud observed them during the day they seemed to be asleep.
