BirdRoost

BirdRoost enables you to register harrier roost counts in an easy way (other species that roost together will be added later). You start by selecting habitat type and weather conditions and subsequently record all individuals that arrive at night (or depart in the morning). Besides selecting species (Hen, Montagu’s, Marsh and Pallid harriers) you can add sex and age as well as the direction the bird arrives from or departs to. After the count you can export your data at any time to your email address.
