Andean Condor Identification Guide

Key Field Marks

• Enormous size, with a wingspan up to about 3.2 m (10.5 ft) among the largest of any living bird
• Overall black plumage with a distinctive white ruff of feathers encircling the base of the neck
• Large white patches on the upper wing coverts, more extensive in males than females
• Bald head and neck with bare skin that ranges from pink to red to grayish and can visibly flush with the bird's temperature or mood
• Adult males have a large fleshy comb (caruncle) on top of the head and a wattle on the neck; females lack the comb and have red (not brown) eyes

How to Tell It Apart from Similar Species

• Turkey Vulture and Black Vulture are both far smaller, lack the white neck ruff and large white wing patches, and soar with different wing postures.
• King Vulture, found mainly in lowland tropical forest rather than high mountains, has a mostly white body with a black flight-feather trim (the reverse pattern) and a brightly colored, ornately fleshy head.
• Sheer size, the pale wing patches, and the white neck ruff make an adult Andean Condor unmistakable among Andean raptors; sub-adults are more uniformly dark and take several years to acquire full adult plumage and head ornamentation.

Habitat & Range

Andean Condors range along the length of the Andes mountains from Venezuela and Colombia south to Tierra del Fuego, favoring high-elevation open grassland and alpine terrain, as well as some coastal areas of Peru and Chile where they scavenge marine carrion. They nest on inaccessible cliff ledges at high elevation and are highly social, often roosting communally.

Behavior

Condors are almost entirely scavengers, feeding on carrion such as dead livestock, wild camelids (like guanaco), and, along the coast, marine mammals. They are masters of soaring flight, riding thermals and mountain updrafts for hours with very little flapping, typically holding the wings flat with the primary "finger" feathers upswept at the tips. Reproduction is slow: pairs generally raise a single chick and often breed only every other year, contributing to the species' vulnerability to population declines.

Voice

Andean Condors lack a syrinx and are essentially voiceless, capable only of low hisses, grunts, and clicking sounds, mainly at close range around carcasses or nests.
