Description


Here's a couple hummingbirds which are part of the Hummingbirds v2 update coming next week. This critically endangered hummingbird, the Juan Fernández Firecrown, is endemic to Isla Róbinson Crusoe (one of a three-island archipelago belonging to Chile. From 1704 to 1709, the island was home to the marooned sailor Alexander Selkirk, who at least partially inspired novelist Daniel Defoe's fictional "Robinson Crusoe" in his 1719 novel.) The hummingbirds troubles began with the clearance and degradation of vegetation by humans since the late 16th century and the impacts of herbivorous mammals (especially rabbits introduced in the 1930s). This has limited the availability, quantity and quality of food resources. Habitat quality is also being degraded by the spread and dominance of invasive plants, most prominently by elm-leaf blackberry (Rubus ulmifolius), maqui (Aristotelia chilensis) and murtilla (Ugni molinae). Introduced predators, such as rats, cats and coatis, have been implicated in the mortality of some birds and may be responsible in part for its decline. Cats have been documented killing firecrowns in town during the non-breeding season. As is true with many island species, firecrowns are easily approached, thus rendering them highly susceptible to predation. Additionally, during its nocturnal torpor, this species is presumed to be very vulnerable to predation. The male is mostly cinnamon orange, excepting dark gray wings, black bill, and iridescent green-gold crown. The female is about 20% smaller. Its under parts are white with a dappling of very small green and black areas. Its crown is an iridescent blue, and the upper parts are blue-green. The The sex ratio is heavily skewed, with three males to every female. The Juan Fernández Islands were designated as a national park in 1935 (protected from 1967) and an UNESCO Biosphere Reserve in 1977. The Chilean government began restoring habitat in 1997, and the islands have been nominated for World Heritage listing. Conservation is being led by the Juan Fernández Islands Conservancy, with support from the American Bird Conservancy, Conservation International, the Hummingbird Society, the Jeniam Foundation, and the Royal Society for the Protection of Birds. Key activities which have already taken place are: the hiring of two island residents as project coordinators; control of invasive plants and herbivores (including volunteer programs for island residents to participate in invasive plant removal), which appears to increase nesting success of the species; invasive predator control (including cat control in the town on Robinson Crusoe); habitat restoration in native forest; a community outreach program aimed at engaging local people and including environmental education programs for local schoolchildren; as well as population surveys and monitoring of active nests, phenology and reproductive success.
