What is the Biggest Parrot in the World? Unveiling the Avian Giants

The quest to identify the world’s biggest parrot takes us on an exciting journey, examining two particular contenders: the Hyacinth Macaw and the Kakapo. These two species exemplify the extraordinary diversity and adaptations found within the parrot family. In this article, we’ll delve into these magnificent birds’ characteristics, habitats, behaviors, and conservation status.

Hyacinth Macaw: The Largest Flying Parrot

The Hyacinth Macaw, known for its bright blue plumage and powerful beak, is the largest flying parrot in the world.


The Hyacinth Macaw (Anodorhynchus hyacinthinus), native to central and eastern South America, stands out as the largest parrot by length in the world. This striking bird measures approximately 1 meter (3 ft 3 in) from the tip of its tail to the top of its head, with a weight ranging between 1.2 to 1.7 kg (2 lb 10 oz – 3 lb 12 oz)​​. Its vibrant blue plumage and bright yellow around its eyes and beak are distinctive​​.


Hyacinth Macaws feed on nuts from specific palm species like acuri and bocaiuva palms, utilizing their strong beaks to crack open even the toughest shells​​.

Breeding and Nesting:

These birds nest between July and December, typically in tree cavities or cliff faces. In the Pantanal region, a significant number use the manduvi tree for nesting​​.


The Hyacinth Macaw is found in three main areas: the Pantanal region of Brazil, adjacent eastern Bolivia and northeastern Paraguay, the cerrado regions of eastern Brazil, and the open areas near the Tocantins River in the Amazon Basin of Brazil​​.

Conservation Status:

Classified as vulnerable, the Hyacinth Macaw faces threats from habitat loss, hunting for food, and the pet trade. However, efforts like the Hyacinth Macaw Project in Mato Grosso do Sul, Brazil, have been instrumental in their conservation​​.

Kakapo: The Heaviest Parrot

The Kakapo (Strigops habroptila), an endemic New Zealand species, is the world’s heaviest parrot. Adult males weigh around 1.5–3 kg (3.3–6.6 lb), and females are slightly lighter, weighing 0.950–1.6 kg (2.09–3.53 lb). They can be up to 64 cm (25 in) long and are notable for their finely blotched yellow-green plumage and owl-style features​​.

Unique Adaptations:

The Kakapo is the only flightless parrot, nocturnal, herbivorous, and exhibits a low basal metabolic rate. It has a unique polygynous lek breeding system and is possibly one of the world’s longest-living birds​​.

Habitat and Diet:

As a ground-dwelling bird, the Kakapo is an excellent climber and feeds on fruits, seeds, leaves, stems, and rhizomes​​.

Conservation Status:

Critically endangered, with a known population of just 247 individuals as of 2023. Conservation efforts, particularly the Kakapo Recovery Programme, have been crucial in preventing its extinction​​.
