Birds in Connecticut

Our list for Connecticut has 201 bird species recorded regularly there: 40 residents, 54 summer visitors, 56 winter visitors, 46 passage migrants and 5 scarce visitors

The list comes from 8.9 million birdwatchers' records from 2019–2024, shared through the eBird Observation Dataset on GBIF. A bird is listed when it was recorded in at least 3 of the 6 years and has a Birdfact species guide, so more species occur here than are listed; the months show when it is recorded most years.
