The Connecticut Bird Atlas was designed to provide comprehensive information about the distributions of all species that occur in the state. With the help of the state’s birding community, we conducted field work during both the breeding season and between November and February, with data collection focused on describing both where each species occurs and how abundance varies across the state. The results of this new data collection, conducted between spring 2018 and February 2022, are presented on this website.

Specific goals include:

• Describe the distribution and abundance of each breeding species.
• Document changes in breeding distribution since the first Connecticut Breeding Bird Atlas, conducted in the 1980s.
• Describe the distribution and abundance of each species during non-breeding periods.
• Identify the most important factors affecting where each species occurs.
• Develop methods for predicting how Connecticut’s changing landscape will affect birds.
• Inform decision making for conservation priority species identified in the State Wildlife Action Plan.
• Make project data available to all stakeholders interested in improving bird conservation in the state.
