Sisserou parrot The Sisserou parrot is a large, critically endangered parrot endemic to Dominica, notable for its role as a national symbol and its restricted montane rainforest range. It has attracted attention from conservation organizations, governments, and researchers from institutions such as the IUCN, BirdLife International, Royal Society for the Protection of Birds, Zoological Society of London, and various Caribbean environmental agencies. Conservation actions have involved collaboration with entities including the Caribbean Community, the United Nations Environment Programme, and regional universities.

Taxonomy and systematics

The species was originally described under a Linnaean binomial and has been treated within the genus Amazona alongside other Neotropical parrots such as Amazona ochrocephala, Amazona ventralis, Amazona leucocephala, Amazona albifrons, and Amazona autumnalis; taxonomic assessments have been published by researchers affiliated with the American Ornithological Society, the International Ornithologists' Union, and the Smithsonian Institution. Molecular phylogenetic studies conducted at institutions like Harvard University, University of Oxford, University of Cambridge, and the Max Planck Institute have explored relationships with Caribbean endemics such as Puerto Rican amazon and mainland congeners described in works from the Natural History Museum, London and the Museum of Comparative Zoology. Historic descriptions appear in catalogs linked to the Royal Society, the Linnaean Society, and early expeditions associated with figures like Carl Linnaeus and collectors whose specimens entered collections at the British Museum.

Description

Adults are large, with a robust bill and plumage predominantly green with violet shoulders and other coloration comparable to descriptions of plumage in accounts by the American Museum of Natural History, the Cornell Lab of Ornithology, the National Audubon Society, and field guides from the Royal Ontario Museum. Morphological measurements recorded in studies from the University of the West Indies, the Smithsonian Tropical Research Institute, and the Neotropical Bird Club note body mass and wing chord consistent with larger Amazona species documented by ornithologists publishing in journals such as The Auk, Ibis, and Journal of Avian Biology. Field photographers and illustrators working with the World Wildlife Fund, National Geographic Society, and the BBC Natural History Unit have highlighted distinguishing features used in identification in citizen science portals managed by eBird, iNaturalist, and regional birding groups.

Distribution and habitat

The parrot is restricted to the island of Dominica in the Leeward Islands and Windward Islands region, occupying montane rainforest and cloud forest on peaks such as those within Morne Diablotins National Park and Morne Trois Pitons National Park, areas also recognized by agencies like UNESCO and the Caribbean Development Bank. Surveys coordinated by teams from the Government of Dominica, Dominica Conservation Association, Durrell Wildlife Conservation Trust, and regional NGOs have mapped populations to elevations and forest types described in reports to the Convention on Biological Diversity and the Ramsar Convention. Historical range contraction has been analyzed alongside land-use records held by the Food and Agriculture Organization and protected area designations administered by the Commonwealth of Dominica.

Behavior and ecology

Social behavior and vocalizations have been documented in field studies undertaken by researchers linked to University of Puerto Rico, the University of Miami, the Royal Botanic Gardens, Kew, and independent ornithologists contributing to publications in Conservation Biology and Bird Conservation International. Flocking patterns observed by survey teams from Zoological Society of London and BirdLife International indicate seasonal movements and territory use that intersect with montane watershed protection efforts supported by the World Bank and regional conservation plans developed with the Inter-American Development Bank. Interactions with sympatric species documented in faunal inventories include observations comparable to community ecology studies from the Caribbean Biodiversity Fund and museum collections at the Smithsonian Institution.

Diet

Dietary studies drawing on radio-tracking and fecal analysis by scientists affiliated with the University of the West Indies, the Smithsonian Tropical Research Institute, and the Durrell Wildlife Conservation Trust show reliance on native fruiting trees and seeds similar to resources cited in reports by the Food and Agriculture Organization and the International Union for Conservation of Nature. Plant species used for foraging are cataloged in collaboration with botanists from the Royal Botanic Gardens, Kew, the New York Botanical Garden, and local herbaria, with implications for habitat management considered by the Caribbean Invasive Species Working Group and the Global Environment Facility.

Reproduction and lifecycle

Breeding biology, clutch size, and nesting requirements have been studied by conservationists from the Durrell Wildlife Conservation Trust, the Dominica Conservation Association, and university teams publishing in outlets like The Condor and Journal of Field Ornithology; nesting in tree cavities in old-growth forest parallels findings reported by researchers at the Smithsonian Institution and the Royal Society for the Protection of Birds. Lifecycle stages and juvenile development have informed captive-breeding and reintroduction planning conducted with partners including the European Association of Zoos and Aquaria, the Association of Zoos and Aquariums, and regional zoological institutions such as Toronto Zoo and ZSL London Zoo.

Conservation status and threats

Classified as Critically Endangered on assessments led by IUCN and BirdLife International, the species faces threats from hurricanes like Hurricane Maria (2017), habitat loss noted in studies by the World Bank and Inter-American Development Bank, invasive species concerns addressed by the Caribbean Invasive Species Working Group, and stochastic risks highlighted in climate analyses by the Intergovernmental Panel on Climate Change. Conservation measures have included protected area establishment with support from UNESCO, captive-breeding programs involving the Durrell Wildlife Conservation Trust and zoo partners, and national legislation enacted by the Government of Dominica coordinated with regional initiatives under the Caribbean Community and funding mechanisms such as the Global Environment Facility and Green Climate Fund. Ongoing monitoring and recovery planning engage research institutions including the Cornell Lab of Ornithology, the University of the West Indies, the Smithsonian Institution, and international NGOs like the World Wildlife Fund.
