Birds (including free flight)

Yellow-green grosbeak

Yellow-green grosbeak, Caryothraustes canadensis

Carl Linnaeus (1707-1778) invented the scientific names we use today. Many of his names were given to dead specimens in European museums, or pictures in books, so the information he had was sometimes incorrect. The laws of nomenclature do not allow for corrections. Thus, even though this large finch actually comes from Panama and Northern South America, the “Canadian” name that Linneaus gave it in in 1766 is still used. A relative of the Cardinal, Rose-breasted grosbeak, and Painted and Indigo buntings, it has always been rare in captivity.

Woodpeckers

Woodpeckers, Picidae

The 216 species of woodpeckers are found across the Americas, Europe, Asia, and Africa, of which 109 live in Mexico, Central, and South America, and the Caribbean. They are important components of the tropical American ecosystem, as other birds, such as trogons, use the nests they excavate in trees. True to their name, their skulls, beaks and tongues are uniquely adapted to extracting insects from trees. Tropical American woodpeckers are uncommon in zoos, but the DWA has done well with four species: Red-crowned woodpecker (Melanerpes rubricapillus), Puerto Rican woodpecker (Melanerpes portoricensis), Panamanian acorn woodpecker (Melanerpes formicivorus striatipectus) and the Golden-naped woodpecker (Melanerpes chrysauchen).

Guiana crested eagle

Guiana crested eagle, Morphnus guianensis

Some of the few captive specimens have been mistaken for the much larger Harpy eagle. This remarkable resemblance extends to juvenile plumage — newly fledged birds of both species have white heads. Crested eagles usually eat smaller monkeys than Harpies, and more often hunt reptiles. Like the Harpy eagle, it is considered Near Threatened, since it requires mature forest. Those at the DWA are now the only birds outside of Tropical America, though this species bred at the Oklahoma City Zoo some years ago.

Ornate hawk-eagle

Ornate hawk-eagle, Spizaetus ornatus

This beautiful bird has always been a rare exhibit. The DWA has had unusual success propagating this species. Young birds have white heads. Weighing less than four pounds, it easily takes such large prey as monkeys, curassows, and macaws. Like the Near Threatened Harpy and Crested eagles, they prefer building nests in Ceibas and other huge trees, but are more tolerant of disturbed forest and not yet considered threatened.

Black hawk-eagle

Black hawk-eagle, Spizaetus tyrannus

The biodiversity of New World rain forests is demonstrated by the abundance of eagles that can be found in one place. This species (in addition to the Ornate hawk-eagle, the Guiana crested eagle, the Harpy Eagle and the Black-and-white Hawk-eagle) all range from Meso-America, through Amazonia and beyond in South America. All five are kept at the DWA, the only place to now do so. Also called the Tyrant hawk-eagle, this rarely-kept species has not yet bred in collections. Fertile eggs have been laid at the DWA.
