When it is recorded
JFMAMJJASOND
Peak month: January. 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
19152026
Recording effort has risen steeply almost everywhere since the 1990s, so a rising line usually shows more observers rather than more animals.
