Satellite tracking of Bulwer's Petrels Bulweria bulwerii in the Canary Islands

Abstract

Capsule The breeding foraging and post-breeding dispersal movements of five satellite-tagged Bulwer's Petrels from the Canary Islands were recorded. Foraging trips lasted 5.6 days in average (n = 3), while the mean distance covered was 1261 km, and foraging areas were located over the continental slope and the adjacent pelagic waters, around 1200-2000 m depth and up to 350 km from the colony. After the chick-rearing period, birds dispersed southwestwards to the tropical waters of the central Atlantic. © 2013 Copyright British Trust for Ornithology.
