Description: This layer shows the movement patterns of 3 black-capped petrels during their non-breeding season from the first tracking study of this species. The black-capped petrel (Pterodroma hasitata) is an endangered seabird with fewer than 2000 breeding pairs restricted to a few breeding sites in Haiti and the Dominican Republic. To date, use areas at sea have been determined entirely from vessel-based surveys and opportunistic sightings and, as such, spatial and temporal gaps in our understanding of the species’ marine range are likely. For example, compare these tracks with the modeled distribution (MDAT) data products under Birds > Individual Species. This study used satellite tags to document individual movement patterns of black-capped petrels. <br/> <br/> During chick rearing, petrels primarily used marine habitats in the southern Caribbean Sea. During the post-breeding period, each bird dispersed north and used waters west of the Gulf Stream offshore of the mid- and southern Atlantic coasts of the USA as well as Gulf Stream waters and deeper pelagic waters east of the Gulf Stream. Petrels used waters located within 14 different exclusive economic zones, suggesting that international collaboration will benefit the development of management strategies for this species. <br/> <br/> The tracks on the map represent the following time periods: <br/> <ul> <li>Bird 175 (blue): 11 July to 30 August 2014</li> <li>Bird 176 (purple): 28 June to 25 August 2014</li> <li>Bird 177 (yellow): 13 May to 4 November 2014</li></ul>
