The Imperial Amazon

The Imperial Amazon, scientifically known as Amazona imperialis, is a magnificent parrot species that holds the distinction of being the national bird of Dominica, a Caribbean island. It is also commonly referred to as the sisserou parrot or Dominican amazon. This species is critically endangered, with its population having drastically declined to an estimated 50 mature individuals in the wild as of 2019. Its image is prominently featured on the national flag of Dominica, symbolizing its importance to the island's heritage.

Description and Characteristics

Imperial Amazons are large parrots, measuring approximately 48 cm (19 inches) in length. Males are notably heavier than females, with males averaging around 900 g (32 oz) and females about 650 g (23 oz). Belonging to the family Psittacidae, they possess zygodactyl feet, adapted for climbing, and a strong, hooked bill coupled with a muscular tongue, which aids in manipulating food. The plumage of both sexes is identical and striking: the chest is a deep shade of purple, while the upper parts and wings are a dark green, accented by black-edged feather tips. The eyes are a vivid mix of orange and red, encircled by a dark brown eye-ring. Juvenile birds exhibit a similar appearance but with a greater prevalence of green plumage and uniformly brown eyes.

Behavior and Diet

These parrots are characterized by their shy nature and are difficult to approach. They typically travel in small groups of three or fewer individuals and are known to sometimes flock with red-necked amazons. They are adept climbers and powerful flyers, often preferring to perch at the very tops of trees, where their plumage provides excellent camouflage, making them hard to detect. Their vocalizations are in the higher frequency range, described as loud, squeaky calls that blend shrieks, squawks, and trills. The diet of the Imperial Amazon is varied, consisting of fruits, seeds, nuts, berries, blossoms, and palm shoots. They show a particular fondness for the fruits of several specific tree species found in Dominica.

Breeding Habits

Imperial Amazons form lifelong pair bonds and are exceptionally faithful to their mates, often seeking a new partner only after the death of their current one. Breeding occurs annually between February and April. The female lays a clutch of two white eggs in a deep cavity within a rainforest tree, a nesting site they tend to return to year after year. The incubation period lasts for 26 to 28 days, during which the female remains on the eggs. Both parents are involved in feeding and caring for the chicks from hatching until they are ready to leave the nest, a process known as fledging, which typically takes place between June and early September. It is common for only one chick to survive to fledging, and pairs usually raise a single chick every other year, though exceptions have been noted.

Distribution and Habitat

The Imperial Amazon is endemic to the island nation of Dominica in the Lesser Antilles. It inhabits the island's mountainous rainforests, typically found at elevations above 600 meters (approximately 2,100 feet). They are frequently observed in areas such as Morne Diablotins and have been reintroduced into Morne Trois Pitons National Park. While primarily found in higher elevations, they have been sighted at lower altitudes, likely for foraging or food storage purposes.

Conservation Status and Threats

The species is critically endangered, facing numerous threats that have led to its precarious population status. Major challenges include the devastating impact of hurricanes, such as Hurricane David in 1979 and Hurricane Maria in 2017, which have severely damaged their habitat. Habitat loss due to selective logging, deforestation, and the expansion of plantations, particularly for bananas, further exacerbates the problem. Human encroachment and disturbance in forest areas also contribute to habitat degradation. Illegal trapping and trading for the black market remain a significant threat, despite educational programs aimed at reducing local demand and deterring illegal activities. Competition for nesting cavities with other species, including red-necked amazons and owls, creates a challenging environment, as does predation by Dominican boas, broad-winged hawks, opossums, and rats. Efforts are underway by conservation organizations and the Dominican government to protect remaining habitats and raise awareness to aid in the survival of this iconic species.
