Parrots of the World — A Field Companion

Few creatures capture the imagination quite like parrots — birds of extraordinary colour, startling intelligence, and uncanny vocal mimicry. With over 400 known species distributed across tropical and subtropical regions, they represent one of the most diverse and evolutionarily successful avian orders on Earth.

Ara macao

Scarlet Macaw

Least Concern Central America Flagship Species

Among the most visually arresting birds on the planet, the Scarlet Macaw inhabits humid evergreen forests from southern Mexico to the Amazon basin. Its plumage — a cascade of crimson, gold, and cobalt — has made it a cultural symbol across Mesoamerican civilisations for millennia. Pairs mate for life and may live beyond 75 years in captivity.

Length: 81–96 cm Wingspan: up to 110 cm Diet: Seeds, nuts, fruit Lifespan: 40–75 years

Strigops habroptila

Kākāpō

Critically Endangered New Zealand Flightless

The world's heaviest parrot is also the only flightless one — a nocturnal, moss-green giant that smells faintly of flowers. Once widespread across New Zealand, introduced predators reduced the population to near extinction. As of 2024, intensive conservation efforts have brought numbers back to over 250 individuals, each known by name to researchers.

Weight: up to 4 kg Status: ~250 individuals Diet: Fruits, seeds, pollen Lifespan: 90+ years

Melopsittacus undulatus

Budgerigar

Least Concern Australia Most Kept Pet Bird

Deceptively small, the budgerigar possesses one of the largest vocabularies of any non-human animal — one individual, Puck, was recorded knowing 1,728 words. In the wild, nomadic flocks of thousands sweep across the Australian interior following rain and the grasses it brings. Their social complexity and capacity for learning continue to challenge assumptions about avian cognition.

Length: 18–20 cm Weight: 30–40 g Diet: Grass seeds Lifespan: 5–15 years

"To watch a flock of wild parrots is to witness intelligence organised into beauty — each bird a sovereign mind, yet the whole a single living expression." — Dr. Irene Pepperberg, Animal Cognition Laboratory, Harvard

Amazona amazonica

Orange-winged Amazon

Least Concern South America

A bird of forest edges and palm groves across northern South America, the Orange-winged Amazon is a vocal and highly social species. It forms enormous roosts at dusk — sometimes tens of thousands strong — creating a spectacle of sound and motion above the canopy. Its remarkable ability to modulate tone allows it to mimic not just words but emotional inflection in human speech.

Length: 31–33 cm Diet: Fruit, seeds, flowers Call: Highly varied Lifespan: 50–60 years

Eolophus roseicapilla

Galah

Least Concern Australia Highly Adaptable

With its rose-pink face and dove-grey wings, the Galah is perhaps Australia's most recognisable parrot — and one of its most adaptable. Unlike many species threatened by habitat change, Galah populations have actually expanded with agriculture, exploiting grain crops and water sources created by farming. They engage in elaborate aerial displays and have been observed using tools in captivity.

Length: 35 cm Weight: 300–400 g Diet: Seeds, grain, insects Lifespan: 40 years
