What does Connecticut’s count include?

  • Every species recorded in Connecticut and accepted by the Avian Records Committee of Connecticut.
  • It marks species known only from sight records, introduced species, and species that are extinct or no longer found in Connecticut.
  • Rare species are marked with an asterisk.

Why might you see a different number?

A state’s count is every species ever accepted on its official list, so a figure from another year, or one that counts something else, won’t match.

Every state’s list follows its own rules: see why the counts differ from state to state.

How do you count your own Connecticut list?

Your state list is every species you’ve seen in the state. If you log your sightings in eBird, it lets you filter your life list by place, a state included (eBird’s My eBird help page, updated March 28, 2025), and the data download you can ask for gives the state of every sighting: our guide shows how to download your own eBird data. On paper, count the species you’ve seen in Connecticut; what is a life list? explains how birders keep their lists.

If you’d like your whole life list in print, Birdfolio turns it into a hardcover book, each species beside a classic painting.
