In recent weeks their have been reports of what could be an invasion by the Common Crossbill into Britain from the continent. This usually means that at some point during August St.Ives will have a varying population. In the past we have had flocks of over 100 Crossbills but we often get smaller flocks.
Crossbills are large finches with the tips of their mandibles crossed, hence the name. They prefer conifer plantations and Larch trees as they feed almost exclusively on the cones.
I will obviously post any sightings as soon as I see or hear some
