Caspian Tern (Hydroprogne caspia)

The Caspian Tern (Hydroprogne caspia) is the largest tern species, known for its striking appearance and powerful flight. As a rare visitor to Montreal, it can be easily mistaken for the smaller Common Tern, but its larger size and uniformly red beak set it apart.

How to Identify

Unlike the Common Tern, the Caspian Tern's beak is uniformly red, lacking a black tip. This bird is notably larger, and its flight is less erratic and slower as it gracefully sails over the water in search of prey.
