This map shows the breeding distribution recorded using the possible / probable / confirmed breeding categories as described in the Breeding season aims. The additional Present category denotes tetrads where species abundance was noted but no breeding code allocated. It generally equates to Possible Breeding (code A1) for widespread resident species but almost certainly includes non breeding individuals for some summer visitors and passage migrants.
