Green Ibis (Mesembrinibis cayennensis)
24 January 2009, CATIE Botanical Garden, Costa Rica
Some authors call this the Cayenne Ibis. This monotypic species ranges
mostly through South America reaching Costa Rica at its northern limit
where it is fairly uncommon.
The green is a subtle iridescence which is dependent on light and angle.
This individual seemed have more of a purple shine. The shaggy looking
neck feathers on the back of the neck are characteristic as is the bare
facial skin. The bill is more substantial and heavier at the base compared
to the more widespread Glossy Ibis (Plegadis falcinellus). The Green Ibis
also has much shorter legs, especially the tibia, cf. the Glossy Ibis. This
individuals legs don't even show up in the short grass.
Note the mud on the bill. Ibis feed by probing in the mud for worms.
