Our list for Anglesey has 180 bird species recorded regularly there: 76 residents, 34 summer visitors, 32 winter visitors, 27 passage migrants and 11 scarce visitors

The list comes from 110,000 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.
