Hurricane Dorian threatens endangered bird species
Those living on the Abaco and Grand Bahama islands recently met Dorian as the hurricane’s 185 mph winds wrecked havoc on the islands, destroying and damaging about 13,000 homes. While the hurricane has raised much concern over the rising death tolls and destruction to the island, it also raised concern for endangered species who call the island home, such as the critically endangered Bahama nuthatch.
The Bahama nuthatch has been in trouble for some time as a 2004 survey reported its population was around 1,800. Three years later, a 2007 survey noted more hurricanes decreased its numbers to a mere 23. By the time Hurricane Matthew struck in 2016 the bird’s population dropped and in 2018 only two were found.

It appears Dorian left very few stones upturned as most of the areas are reportedly still under water and coniferous forests are being killed by saltwater flooding.
“It is obviously a humanitarian disaster for people living in these northern islands, and the extent is as yet unknown, but we hope that international medical and infrastructure aid will arrive rapidly and generously,” Diana Bell, professor of Conservation Biology at the University of East Anglia in the United Kingdom, told Earther. “It is also highly likely to have also been an ecological disaster affecting the already fragmented areas of Caribbean pine forest which support endemic avifauna.”
Aside from trees and the Bahama nutshell, some scientists are worried about the Bahama warbler and the more well-known Kirtland’s warbler, a bird that lives among the pineyards during the winter season.
In addition to the nuthatch and the warblers, as recent as July, avifauna in the Bahamas was reported at 374 species, according to Avibase – Bird Checklists of the World.
According to a National Climate Assessment, researchers say warmer ocean climes and higher sea levels from climate change will further intensify hurricanes in the Atlantic and Caribbean, though some research suggests hurricanes are slowing down but causing longer impacts. Nonetheless, hurricanes of all categories could cause irreparable disaster for all island inhabitants.
