Crossbill Foraging Style


Phil Brown

White-winged Crossbills can eat up close to 3,000 seeds in a day. How does one bird get access to so many seeds?
It's the structure of this bird’s unique crossed bill that aids them in obtaining seeds. Physical adaptation allow  the
White-winged Crossbill get at seeds from pine cones that other species with ordinary bird's bills can’t. What appears
at first to be an odd bill abnormality is an extremely advantageous feature.
