Owl Pellets

Owl Pellets

    Yesterday we visited the arboretum at the University of Guelph and searched for a Barred Owl Strix varia which had been reported there. Evidently this bird moves around, for the closest we came to locating it was a tree with "whitewash" and a few pellets underneath it. Pellets are made up of a bolus of the undigestible parts of the owl's prey species and the fur and bones of small mammals can be seen here. For the competent observer these remnants reveal a great deal about the owl's diet.
