There are three common species of ibises in North America; the Glossy Ibis, White-faced Ibis and the White Ibis. The Scarlet Ibis is not often seen and is a southern bird found in South America and in some of the Caribbean islands.
The ibises are some of the most numerous wading birds seen in the southern and central states. Although their numbers are declining from loss of habitat, like so many other types of birds, they can be seen on the mud flats next to the oceans and in the interior of the country, feeding in marshes and along roads and highways.
ABA - American Birding Association This site represents an organization that maintains official records of all birds species that have been proven to have been seen inside the perimeters of the North American Continent and the surrounding bodies of water. Regular revised versions are posted to keep the bird list current at all times. This is the list used by all serious birders over their lifetime. You may be aware of the movie called the "Big Year". It was with this list that all the competing birders used in an attempt to set a new record as to how many bird species that could be seen by an individual birder in one calendar year.
