Most least terns breed along the coast but one subspecies is known to come inland and breed along rivers and lakes. They are called interior least terns and this subspecies was added to the endangered list in 1985 due to habitat loss. They are still on the list but their population is increasing. It was exciting to find out some have been breeding near my favorite lake.
