Birds in Mayo

Our list for Mayo has 163 bird species recorded regularly there: 58 residents, 31 summer visitors, 23 winter visitors, 36 passage migrants and 15 scarce visitors

The list comes from 63,000 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.
