Green Ibis Mesembrinibis
cayennensis
Brazilian name:
coró-coró |
 |
Mato Grosso, Brazil
December 2006
The Green Ibis is distributed from Costa
Rica through to the Orinoco and Amazon Basins and has been seen
(rarely) as far south as Rio Grande do Sul. It is found in wet
forest, gallery forest and swampy areas.

The overall impression is of
a dark bird but in good light there is a lot of subtle colour.
The head is dull black while the nape has glossy petrol-green
hackles. The bill is a pale jade green though many descriptions
say that it is dull black. I suspect that it changes colour
during the breeding season. Upperparts are bronzy-olive with a
greenish tinge. In flight note that the short legs do not extend
beyond the tail. |

It
is usually seen singly or in pairs though I saw a small family
group of six birds on the Cristalino River.
It
is shy, easily spooked and is most active at dawn and
dusk.
Its
Brazilian name reflects its call of
coró-coró as you can hear on xeno-canto and in Jeremy Minns' excellent
recording where the knocking sounds are probably made by
monkeys.
