White-winged Crossbills - The Holden Arboretum














White-winged Crossbills are a special visitor in the winter. They migrate down from Canada when food is scarce. They can be found in conifer collections as they eat seeds primarily in hemlocks, spruces and tamaracks. Their beaks are designed for the task of removing seeds from the conifer cones. An individual crossbill is capable of eating up to 3000 conifer seeds in one day. This winter white-winged crossbills have been reported throughout Ohio. At Holden they have been seen in the conifer collection and the hemlocks off of the woodland trail. These pictures were taken in the conifer collection.
