Flores waters are where the local endemic Monteiro’s Petrel feeds, and while in this westernmost-WP location, we focus on searching for the gadfly petrels.

We time the pelagic operation exactly at the median date when the first arrival of the winter breeder Grant's Storm Petrel and the Monteiro’s Petrel are still present in good numbers before leaving Azorean waters. Our aim is to test all the known ID tools in the separation of these cryptic species with birds at sea. At this time of year, the sea is calm to moderate, providing perfect conditions for attracting storm petrels to our chum slick.

Hadoram is still collecting material for the future volume of the Storm Petrels of the World, where he has already studied most populations of the Band-rumped complex with birds at sea, handled birds in the colonies, and most museums worldwide. In recent years, he has especially studied the winter and summer breeders of Porto Santo.
