Size Comparison
Habitat Comparison
Downy Woodpecker
Deciduous and mixed forests, orchards, parks, and suburban areas. The most common woodpecker at feeders in North America.
角雕
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'.
角雕
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.
角雕
Central and South America from southern Mexico through Brazil and northern Argentina. Range is shrinking due to deforestation.

Short, chisel-shaped, dark bill — noticeably shorter than the similar hairy woodpecker
角雕
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.
角雕
角雕是美洲最大的猛禽之一，翼展可达224厘米。头部具灰白色双羽冠，体羽黑白对比分明，爪极为强大有力。分布于墨西哥至玻利维亚的热带低地雨林，以树栖哺乳动物为主食，包括树懒和猴子。飞行速度快，是雨林顶级捕食者。
