Are there eagles in Puerto Rico?

Bald Eagle: a rarity, not a resident

The U.S. Fish and Wildlife Service describes the Bald Eagle as the only eagle solely native to North America, with a range that runs from Alaska and Canada to northern Mexico. Puerto Rico sits outside that range, which is why SOPI's 2006 catalog labels it Accidental: a bird that has arrived exceptionally, with no established population or documented nesting.

Accidental does not mean impossible. It means every report should be treated as an extraordinary record, backed by photographs and verifiable details. In this atlas's data, the Bald Eagle is an accidental wetland visitor; there is no season when it is expected and no place where it can reliably be found.

Osprey: the eagle-like bird you will actually see

The Osprey (Pandion haliaetus) is 21–23 inches long with a 5–6 foot wingspan. It is dark above and white below, with a black stripe through the eye and black wrist patches under the wing. In flight it holds its long wings bent at the wrist, and at a distance it can suggest a large gull more than a hawk. It fishes by plunging feet-first into the water.

It is not among the nesting species in the breeding atlas, so in Puerto Rico it is a visitor. Satellite tracking published in the Journal of Raptor Research shows that eastern North American Ospreys funnel through Florida, cross Cuba and Hispaniola, and then fly over the Caribbean to South America; some winter on Caribbean islands. Look for it over bays, coastal lagoons, and reservoirs.

How to tell a Bald Eagle from an Osprey

An adult Bald Eagle has a white head and tail on a brown body; the belly is dark, not white. Immatures are mottled brown and white and do not finish their white head until 4–5 years old. It is much larger: females reach wingspans of about 8 feet and weights of 14 pounds. This atlas's trait data gives an average mass near 4.7 kg, compared with about 1.5 kg for the Osprey.

The Osprey has a white belly, a white head crossed by a black mask, and narrow wings bent into a shallow M. If the bird has a white belly and a mask, it is almost certainly an Osprey. If you see a huge dark-bodied bird with a white head and tail, or a brown immature with a very large yellow bill, document it before drawing a conclusion.

Resident raptors mistaken for eagles

The Red-tailed Hawk is the everyday large raptor. The atlas found it in 355 of 479 hexagons, across all habitats and elevations, including towns and urban areas, though it is most numerous in the mountains. It soars in circles over highways and hills and is the most likely explanation when someone reports an eagle over the island's interior.

Two other raptors are far scarcer. The Broad-winged Hawk is a rare endemic subspecies, mostly restricted to El Yunque, Carite, and Río Abajo; the atlas gathered only 15 records. The Puerto Rican Sharp-shinned Hawk is an endangered subspecies of montane forests and shade coffee, with just 20 records in eight hexagons. Neither is eagle-sized.

If you think you saw a Bald Eagle

Photograph the bird from several angles, especially the belly, head, tail, and bill, and note the date, time, exact location, and behavior. Compare it with Osprey, Red-tailed Hawk, Turkey Vulture, and Magnificent Frigatebird, the large birds most often seen soaring. A reviewable record is worth more than a story, and it can be added to eBird or submitted for review by the local ornithological community.

Keep your distance. The Bald Eagle came off the federal endangered species list in 2007, but it remains protected by the Migratory Bird Treaty Act and by the 1940 Bald and Golden Eagle Protection Act, which prohibit pursuing or disturbing it and possessing its feathers, nests, or eggs without a permit. Do not pick up raptor feathers you find.

Are there eagles in Puerto Rico?

There are no resident eagles. The Bald Eagle is classified as Accidental by the Puerto Rican Ornithological Society, and the breeding atlas documented no eagle nesting on the island. The bird usually called an eagle is the Osprey, a fish-eating raptor that visits coasts and reservoirs.

Is there a Puerto Rican eagle?

There is no eagle species endemic to Puerto Rico. The island's own raptors are subspecies such as the Broad-winged Hawk and the Puerto Rican Sharp-shinned Hawk, both scarce. The most common large raptor is the Red-tailed Hawk.

Are there bald eagles in Puerto Rico?

Only as an accidental visitor. Its natural range runs from Alaska and Canada to northern Mexico, and SOPI's 2006 catalog marks it as Accidental. Any sighting needs clear photos, a date, and a location to be evaluated.

Is the Osprey an eagle?

Not strictly. The Osprey (Pandion haliaetus) is a fish-specialist raptor, separate from true eagles such as the Bald Eagle. It is recognized by its white belly, black eye mask, and wings bent at the wrist.

What large bird soars over Puerto Rico's mountains?

It is almost always the Red-tailed Hawk, the most widespread resident raptor; the atlas found it in 74% of hexagons. Turkey Vultures also soar, and near the coast so does the Magnificent Frigatebird, two large birds worth ruling out.

Is it illegal to keep an eagle feather?

Under the 1940 federal law protecting Bald and Golden Eagles, possessing their feathers, parts, nests, or eggs without a permit is prohibited. Raptors in general are also protected by the Migratory Bird Treaty Act, so the safe choice is not to collect feathers.
