Size Comparison
Habitat Comparison
Downy Woodpecker
Deciduous and mixed forests, orchards, parks, and suburban areas. The most common woodpecker at feeders in North America.
Northern Gannet
Open ocean and coastal waters. Breeds in dense colonies on steep rocky islands and sea stacks.
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'.
Northern Gannet
Loud, harsh 'urrah-urrah' grunting and croaking at breeding colonies on sea stacks. Also gives a softer 'karrr' in flight. Large colonies are extremely noisy during the breeding season.
Geographic Range & Migration
Downy Woodpecker
North America from Alaska and Canada south through the United States, excluding the arid Southwest.
Northern Gannet
North Atlantic, breeding from Newfoundland and Gulf of St. Lawrence to Norway, Iceland, and Britain. Winters at sea south to the tropics.

Short, chisel-shaped, dark bill — noticeably shorter than the similar hairy woodpecker

Brilliant white body with black wingtips and a golden-yellow wash on the head and nape. Blue-grey bill with dark lines and pale blue eye-ring.
Long, straight, pointed, pale blue-grey bill with serrated edges
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.
Northern Gannet
The northern gannet is a spectacular plunge-diver, folding its two-meter wingspan into an arrow shape to hit the water at up to 100 km/h. Air sacs under the skin and a reinforced skull protect it from the impact. Bass Rock in Scotland hosts over 150,000 gannets, the largest single colony of any seabird in the world.
