When it is recorded

Peak month: July. Records cluster in the months an animal is present and being looked for, so a summer peak can reflect observer effort as much as the animal.

Records over time

Recording effort has risen steeply almost everywhere since the 1990s, so a rising line usually shows more observers rather than more animals.
