Downy Woodpecker
Deciduous and mixed forests, orchards, parks, and suburban areas. The most common woodpecker at feeders in North America.
Griffon Vulture
Mountains, cliffs, and open grasslands. Nests on cliff ledges in colonies. Requires thermals for soaring flight.
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'.
Griffon Vulture
Generally silent; hisses and grunts at carrion with other vultures. Gives low croaking 'arrr' near nest. At colonies produces cackling and grunting — not melodic vocalizations.
Geographic Range & Migration
Downy Woodpecker
North America from Alaska and Canada south through the United States, excluding the arid Southwest.
Griffon Vulture
Southern Europe, North Africa, the Middle East, and Central Asia. Resident in most of its range.

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.
Griffon Vulture
The griffon vulture is one of Europe's largest flying birds and a crucial scavenger in Mediterranean ecosystems. These social birds nest in large cliff colonies and can soar for hours using thermals without flapping. Vulture populations faced a crisis from the veterinary drug diclofenac, which proved fatal when consumed through contaminated carcasses.
