Our two species of Cormorants share a rock on a sunny morning. The larger bird on the left with the white patch in the throat is a Great Cormorant. They have a worldwide distribution but in North America they are restricted to Greenland and the Canadian Maritimes in the summer and the northeastern US coast in the winter. The smaller bird is a Double-crested Cormorant whose range is limited to North America. I live at the northern edge of their winter habitat so the two can be spotted mingling on our rocky coasts for a few months.
