Wreathed Hornbill
A species of
hornbill,
also commonly known as Bar-pouched Wreathed Hornbill, and with the
scientific name Rhyticeros undulatus. It is found from
India and Bhutan, through mainland
Southeast Asia and the Greater Sunda Islands, except in Sulawesi. In
Thailand, where this species is known as
nok ngeuak
krahm chang, it occurs in the vicinity
of the border with
Myanmar and
Malaysia, and in areas near the Thai border
to the North and West of
Cambodia,
as well as in Khao Yai National Park and around
Krabi.
With a length of up to 115 centimeters, males are slightly larger
than females, who measure only up to 98 centimeters.
Both sexes are predominantly black, with a white tail, which is
often lightly stained yellowish; a pale yellowish bill, with
a darker, corrugated base; and a gular pouch,
which is blue with
females and yellow with males (fig.), yet both with a black lateral streak on the
underside (fig.).
Both males and females have red eyes and reddish bare skin patches
around the eyes. In addition to this, males have a shaggy, brown,
mane-like crown, that runs to the back of the neck, and the throat
and head-sides are brownish-white, whereas with females the head,
neck and breast are entirely black. Besides perching on tree
branches, they also regularly descend
to the forest floor (fig.),
where they search for fallen fruits. It is similar in appearance to
the
Plain-pouched Hornbill (fig.).
