NNBW takes place each year from 14-21 February, and after more than 19 years it is now an established part of the ornithological calendar.

NNBW aims to encourage everyone to put up nest boxes in their local area in order to promote and enhance biodiversity and conservation of our breeding birds and wildlife.
