Ibis Information
Ibis are found in North America, Africa,
Madagascar, Eurasia (except the northern areas), Australia, Central and South
America, and Trinidad. There are 33 species in the world. All of which are
strong fliers and swimmers. They are true wetland birds, found in fresh or salt
water, marshes and swamps. All are gregarious, nesting in colonies in trees.
They travel in flocks.
The Ibis family is an ancient group. The Latin word has Greek origins meaning "Religious worship, sacred bird". Fossil records go back 60 million years. Record in human history traced to 5,000 years. Ancient Egyptians venerated the old world sacred Ibis, as part of their religion. The birds are often mummified and buried in temples with the Pharaohs. Of all species of Ibises, the most widely distributed is the Glossy Ibis. Commonest in the new world is the White Ibis, and the most beautiful is the Scarlet Ibis.
Back to Top Scarlet Ibis
The Scarlet Ibis is one of the national birds of Trinidad and Tobago.
The Scarlet Ibis is scarlet in colour - the feathers being coloured through the synthesis of carotene present in some of their food (Fiddler and Aratus crabs, shrimp, algae and aquatic insects). The black pigment in the primary feathers is thought to give extra strength to the wing tip. Long neck counters long legs for reaching water surface and mud flats. The long legs are useful for wading in marshy ground, mud flats and mangrove stands. The Scarlet Ibis is long-lived
- It can live up to 18 years in captivity. Ibis are considered adults when they
are about 2 years old- by this time they have gained their bright red colour.
They follow an elaborate courtship and usually pair for life.
The
Wild Fowl Trust now has a breeding population of about 8 Scarlet Ibis.
