Size Comparison
Habitat Comparison
Downy Woodpecker
Deciduous and mixed forests, orchards, parks, and suburban areas. The most common woodpecker at feeders in North America.
Harpy Eagle
Tropical lowland rainforests, requiring large tracts of continuous forest with tall emergent trees for nesting.
Song & Call Comparison
Downy Woodpecker
A sharp 'pik' or 'peek' contact call. Drums on resonant branches with a rapid, light tattoo — softer than larger woodpeckers. Also gives a high descending whinny 'keeer-keeer'.
Harpy Eagle
Rarely heard; emits mournful whistled screams 'wheee-oo' and low croaking grunts near the nest. Vocalizations poorly documented given its remote Amazonian habitat.
Geographic Range & Migration
Downy Woodpecker
North America from Alaska and Canada south through the United States, excluding the arid Southwest.
Harpy Eagle
Central and South America from southern Mexico through Brazil and northern Argentina. Range is shrinking due to deforestation.

How to Tell Them Apart
Downy Woodpecker
Black and white plumage with a broad white stripe down the back. Black wings with white spots. Males have a small red patch on the nape.
Short, chisel-shaped, dark bill — noticeably shorter than the similar hairy woodpecker
Harpy Eagle
Slate-black upperparts and head with a pale grey breast and white underparts with black barring. A distinctive split grey crest rises when the bird is alarmed.
Massive dark hooked bill, one of the largest of any eagle
About These Birds
Downy Woodpecker
The downy woodpecker is the smallest and most widespread woodpecker in North America. Its small size allows it to forage on thin branches and weed stems that larger woodpeckers cannot access. Downies often join mixed-species flocks in winter, benefiting from the extra vigilance of multiple species watching for predators.
Harpy Eagle
The harpy eagle is among the most powerful raptors in the world, with talons as large as a grizzly bear's claws. It is the national bird of Panama. Deforestation poses the greatest threat to this species, as each breeding pair requires a vast territory of undisturbed forest.
