Raptors, or birds of prey, like the eagle, owl and hawk, have large, strong, hooked bills that bite and tear flesh while their feet immobilize the prey.

Willow
balsam willowSalix pyrifolia Andersson
There are more than 50 species of willow throughout Canada, many of which grow as shrubs. The bark of willow trees produces salicin, the active ingredient in aspirin. The leaves of willows are distinguishable from all other Canadian broadleaves. In general their leaves are long and narrow, are pointed at both ends, and have short petioles (leaf-stalks) in comparison to the length of leaf-blades. We present a generic silhouette of a willow tree along with a list of 23 species names and accompanying botanical authorities.
