The Olive-throated Parakeet (*Eupsittula nana*), a vibrant member of the Arini tribe, is a small, energetic parrot native to the Caribbean lowlands from Mexico to Panama. Easily identified by its namesake feature—a subtle, warm olive-green wash on the throat and upper chest—this parakeet sports a predominantly bright green body, contrasting sharply with its pale, horn-colored beak and a distinctive blue flight feather edging visible in flight. A special behavioral trait is its loud, rolling "chur-ree" call, often given in fast-flying flocks, and it is one of the few parakeets known to nest colonially in active arboreal termite mounds, a unique adaptation that provides both shelter and insulation for its eggs.

Faits amusants

Despite its name, the olive-throated parakeet is a master of vocal mimicry, often incorporating the sounds of car alarms, ringing phones, and even chainsaws into its natural, scratchy calls. It has a peculiar habit of sleeping upside-down like a bat, clinging to the underside of a branch with its feet, a behavior rarely seen in other parrots. This species also engages in "anting," where it will crush ants and rub them through its feathers, possibly to use the formic acid as a natural insecticide and fungicide.

Habitats et répartition

The Olive-throated Parakeet is found in a variety of lowland and foothill environments, primarily inhabiting tropical and subtropical forests, forest edges, and semi-open areas with scattered trees. It is also common in secondary growth, plantations, and cultivated lands such as mango orchards and agricultural fields, often near water sources. Its geographical range extends from southern Mexico through Belize, Guatemala, Honduras, and Nicaragua, continuing into central Costa Rica and western Panama. The species is generally resident within this region, occurring from sea level up to around 1,500 meters in elevation.

Comportements & Reproduction

The Olive-throated Parakeet is highly social, forming flocks that roost and forage together communally. Mating pairs are monogamous, with strong pair bonds reinforced through mutual preening and allofeeding. Breeding typically occurs during the dry season, and nests are established in cavities, often in arboreal termite mounds or decaying tree trunks. Both parents share incubation duties for the 23–24 day period, and later cooperate in feeding the chicks. A unique reproductive strategy includes the frequent use of active termitaria, where the birds excavate a nesting chamber; the termites repair the outer wall, creating a stable, insulated microclimate that protects eggs and nestlings from predators and temperature extremes. Brood size is usually three to five eggs, and fledglings remain dependent on parents for several weeks after leaving the nest, often joining juvenile crèches within the larger flock.

Alimentation

The Olive-throated Parakeet (Eupsittula nana) is primarily a frugivore and granivore, with a diet centered on a wide variety of fruits, seeds, and berries found in its tropical and subtropical forest habitats. They are known to feed heavily on the fruits of trees like figs and palms, and will also consume cultivated crops such as mangoes, papayas, and corn, which can bring them into conflict with farmers. An interesting fact about their feeding behavior is that they often forage in noisy, social flocks, and they use their strong, curved beaks not only to crack open hard seeds but also to climb and manipulate their food while hanging upside down. Additionally, they have been observed supplementing their diet by visiting clay licks, a behavior common among parrots that is believed to help neutralize toxins found in unripe or certain seeds and fruits they consume.

Couleurs

The Olive-throated Parakeet is primarily bright green with a paler, olive-brown throat and upper chest. Its wings show blue primary flight feathers, and the tail is long and pointed, green above with reddish-brown tips underneath. The bare white eye-ring and horn-colored beak are distinctive. Its green plumage provides effective camouflage in tropical forest canopies.
