Spotted by
The largest tern in the world, recognizable by its impressive size, shaggy black cap, and massive, bright red bill. It's a powerful and skilled angler of fish.
Where to spot
Found on all continents except Antarctica, breeding on coastlines, large lakes, and estuaries. Winters in warmer coastal and inland waters.
How to spot
Identify by its immense size (nearly gull-sized), large bright red bill with a dark tip, and shaggy black cap. Its call is a deep, hoarse "karr-ahh" or "kraaah." Look for its powerful flight and characteristic plunge-diving behavior.
When to spot
Best observed during the breeding season (spring to summer) at nesting colonies or during migration along major waterways and coastlines.

The Caspian Tern's diet consists almost entirely of fish, which it catches by plunge-diving from considerable heights, often carrying quite large fish in its formidable bill.
