Forster's Terns are the only terns restricted almost entirely to North America throughout the entire year.
Spawning common carp are often so vigorous that they can dislodge Forster's Tern eggs from floating nests.
Forster's and Black Terns breed near each other in the marshes of the refuge. Wandering semi-precocial young may account for many observations of each species feeding the other's young.
