Habitat Comparison
Downy Woodpecker
Deciduous and mixed forests, orchards, parks, and suburban areas. The most common woodpecker at feeders in North America.
Great Blue Heron
Wetlands of all types including marshes, swamps, riverbanks, lake edges, and coastal shores. Also hunts in fields and meadows.
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'.
Great Blue Heron
Deep, harsh, croaking 'frahnk-frahnk' call in flight. Also gives low guttural grunts at the nest. Alarmed birds give repeated croaks. Mostly silent for such a large wader.

North America from Alaska and Canada south through the United States, excluding the arid Southwest.
Great Blue Heron
North and Central America from Alaska and southern Canada to the Caribbean and Galapagos Islands.

Long, dagger-like yellowish bill
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.
Great Blue Heron
The great blue heron is the largest heron in North America, standing up to 1.4 meters tall. These patient hunters can stand motionless for extended periods before striking at prey with remarkable speed. They nest in large colonies called heronries, often returning to the same site year after year.
