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.

Masked Booby makes first appearance in Tubbataha in 20 years

First sighting of Masked Booby in Tubbataha after 20 years

It was a Masked Booby (Sula dactylatra), a large and strikingly plumaged seabird, that was last seen on Bird Islet in the North Atoll of the Tubbataha Reefs Natural Park (TRNP), Palawan, in 1995.

The Masked Booby, which is the biggest and heaviest of the six surviving booby species in the bird family Sulidae, was observed on the mornings of May 11 and 12 by a survey team led by environment and natural resources management specialist Arne Jensen, who has studied the seabirds in Tubbataha for more than 25 years and is chief consultant of the Tubbataha Management Office on the management of seabirds.

The team was on Bird Islet, which is about 170 kilometers southeast of Puerto Princesa, to conduct a census of seabirds and their breeding areas in TRNP. The team has held several surveys over the past years but this is the first time that it has recorded the Masked Booby.

The Wild Bird Club of the Philippines Checklist of Birds of the Philippines 2016 declares the Masked Booby as “Extirpated,” with the last sighting of a resident bird from “North Islet, Tubbataha Reefs, Palawan (1995).” The checklist notes one sub-adult documented “off Babuyan Islands, Cagayan (2003).” With the Philippine population believed to be gone, any new sighting is presumed to be of individuals that have strayed from abroad.

The team observed the lone Masked Booby standing and walking among Brown Booby (Sula leucogaster) and Greater Crested Tern (Thalasseus bergii), which, along with Brown Noddy (Anous stolidus), Black Noddy (Anous minutus), Sooty Tern (Onychoprion fuscatus), and Red-footed Booby (Sula sula), roost and nest in dense colonies on the uninhabited islet.
