Boat-billed
Heron
(Cacatuagalerita)
Photographed at Reid Zoo, Tucson, Arizona Mar 2010
Like night-herons
but unlike most other heron species, Boat-billed Herons have short, thick
necks, very large eyes, massive but relatively short beaks, and they are
nocturnal (thus the oversize eyes). Boat-bills are even more strictly nocturnal
than night herons.
The Boat-billed
Heron communications is different from regular herons by its vocal and
mechanical sounds such as bill-pops that sound like handclaps. This is
different from the visual gesturing that other herons do. Also, it mainly eats
alone by flying from the common roost to individual feeding areas.
Occasionally, it will feed in groups.
