Corvids, which are crows and jays, are classified by their harsh voices and their aggressive manner, both of which draw attention to themselves; large and often very gregarious birds. Most corvids have bristles on their nostrils, located on very powerful, all-purpose beaks built specially for handling their varied diet ( berries, fruits, seeds, invertebrates, small mammals and carrion). Here are most of the species that you may see in the Calgary region, the only one missing, is the colorful Steller’s Jay.
