Seasonal Presence and Relative Frequency of Selected Species

Connecticut Birding Highlights

This list summarizes the seasonal presence of selected bird species in Connecticut, indicating whether each species occurs year-round, during the breeding season, or during the non-breeding season (winter and migration). Within each seasonal category, species are numbered and ordered from least to most frequently observed in the United States based on eBird frequency data. This ordering reflects how commonly a species has been observed by U.S. birders over time and is used here as a relative priority indicator, not as a measure of local abundance or the likelihood of encountering a species at a specific site or season within Connecticut.
