Whiskered Tern vs Black Tern: common questions
How can you tell a whiskered tern from a black tern?
The whiskered tern keeps a sharp white cheek stripe against dark grey underparts, while the black tern develops an almost entirely black body during the breeding season, making the two closely related marsh terns distinguishable at a glance.
Do the whiskered tern and black tern hunt the same way?
Yes, both species hunt mainly by hovering low over the water and dipping down to snatch insects and small fish, a shared technique typical of the small group of marsh terns they both belong to.
Do the whiskered tern and black tern share the same range?
They overlap in parts of Europe and Asia, but the whiskered tern extends further into Africa and Australia, while the black tern is also found breeding across parts of North America where the whiskered tern does not occur.
