First recorded
Whitethroats are migratory birds. They are summer visitors to the UK. Nature's Calendar monitors how early or late whitethroats arrive in the UK in spring.
In a location that you monitor regularly (at least once a week), record the date that you first see a live, active whitethroat after their winter absence. This is usually from April/May.
