As regular CFZ-watchers will know, for some time Corinna has been doing a column for Animals & Men and a regular segment on On The Track... particularly about out-of-place birds and rare vagrants. There seem to be more and more bird stories from all over the world hitting the news these days so, to make room for them all - and to give them all equal and worthy coverage - she has set up this new blog to cover all things feathery and Fortean.

DOMINICA – Rare seabird found in Dominica

Added by Barbados Today on July 29, 2015.

ROSEAU –– A team of scientists from EPIC and Dominica’s Ministry of Agriculture and Fisheries have recorded –– for the first time –– 968 of the diablotin, also known as the black-capped Petrel, over the mountains of Dominica, for which the last confirmed date of nesting of that species is 1862.

This rare seabird was once abundant on Dominica, but thought to be extirpated in the late 1800s due to overhunting and the introduction of mammalian species. Observations made with radar and supplemented by detection of vocalizations showed large numbers of petrels flying between the sea and potential nest areas in the island’s highest peaks. Details of the expedition are being released at the 20th International Meeting Of Birds Caribbean, taking place now in Kingston, Jamaica.

Adam Brown, co-founder and lead scientist at EPIC states: “Finding this colony of petrels on Dominica is a real game-changer for black-capped petrel conservation. For years we thought the only remaining colonies of petrels were on Hispaniola, where nesting habitat is diminishing at an alarming rate and pressures of human activity are significant.

“Dominica is an island-nation where nature conservation is a high priority and forests needed by petrels are well protected; so we now have a huge new opportunity to undertake conservation efforts to preserve this imperiled species.”

Biologists from EPIC and the Forestry, Wildlife and Parks Division of Dominica’s Ministry of the Environment teamed up in January to do a systematic survey of the entire island of Dominica to locate the diablotin and determine its status. The diablotin is a very difficult bird to study, as it is a seabird that comes to shore only for a few months of the year to breed, flying into forested mountains at night to underground burrows. A portable marine radar array and night vision scopes allowed biologists to locate, identify and count flying petrels in in the dark.

Radar Tracking Project to Help Protection of Endangered Caribbean Petrel

Published by surfbirds on May 1, 2013 courtesy of American Bird Conservancy

A month-long, high-tech project to survey one of the Caribbean’s most endangered birds, the Black-capped Petrel, has succeeded in identifying six previously unknown areas of petrel activity in the Dominican Republic: three flight corridors, and three possible nesting locations for the bird. Surveys also were conducted at seven sites in Haiti, a combination of new sites and areas where petrel activity was known previously. 

Numbers of Black-capped Petrels have been in precipitous decline over the last 50 years with only an estimated 1,000 – 2,000 pairs remaining. Although they historically nested on other islands in the Caribbean, they are currently known to nest only on the island of Hispañiola – an Island shared by two sovereign nations, Haiti and the Dominican Republic. 

Scientists hope that the surveys, which were carried out by Environmental Protection in the Caribbean (EPIC), Grupo Jaragua, and Société Audubon Haiti with support from American Bird Conservancy and the US Fish and Wildlife Service, will result in the identification and better management of critical breeding locations. 

Black-capped Petrels only visit their nesting colonies at night, so scientists involved in the effort used modified marine radar equipment to survey locations in several mountain ranges in the two countries, principally in the southwestern and central portions of the island. Although petrels were detected in all of the 15 survey sites, only two sites registered large numbers of detections.
