Size Comparison
Habitat Comparison
American Robin
Lawns, parks, gardens, farmland, and forest edges. One of the most familiar birds in suburban North America.
Griffon Vulture
Mountains, cliffs, and open grasslands. Nests on cliff ledges in colonies. Requires thermals for soaring flight.
Song & Call Comparison
American Robin
A clear, caroling song of 2-3 note phrases: 'cheerily, cheer-up, cheerio'. Sings from dawn perches. Sharp 'tut-tut-tut' alarm call and thin 'seeee' flight note.
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
American Robin
North America from Alaska and Canada to Mexico. Northern populations migrate south in winter; southern populations are largely resident.
Griffon Vulture
Southern Europe, North Africa, the Middle East, and Central Asia. Resident in most of its range.

About These Birds
American Robin
The American robin is widely regarded as a harbinger of spring across North America. Despite its name, it is a true thrush unrelated to the European robin. American robins produce two to three broods per year and are among the earliest birds to sing in the morning chorus.
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.
