The Marine Bird Distribution Working Group aims to support collaborative coordination of research and monitoring to increase knowledge of marine bird distributions in the U.S. Atlantic. The working group uses the best available science to improve our understanding of the effects of offshore development on marine bird species. This working group was formed in support of the RWSC’s Bird and Bat Subcommittee. The objectives of the working group include:
For more information on the efforts of this working group, including the group’s work plan, meeting summaries, and slide decks, visit the Marine Bird Distribution Working Group SharePoint.
The working group has compiled various existing resources related to the above objectives, including existing guidance for conducting surveys, key scientific literature on changes in marine bird distributions in relation to offshore development, species prioritization efforts, species distribution data.

Seasonal maps of the spatial distributions of 49 marine bird species in U.S. Atlantic Outer Continental Shelf waters were developed using sighting survey data from over three decades from the Northwest Atlantic Seabird Catalog database along with Eastern Canada Seabirds at Sea data. These relative density maps can be used to aid ocean planning in the region and guide future data collection efforts. Data is available for download on the Northeast Ocean Data Portal.
