The Black Tern and Louisiana Waterthrush are distinct in both appearance and behavior. The Black Tern is a small, dark seabird with a buoyant flight, while the Louisiana Waterthrush is a terrestrial warbler with a distinctive tail-wagging habit. Their habitats rarely overlap, with the tern favoring wetlands and the waterthrush preferring forested streams.

1. Location and Habitat: Black Terns are found in open wetlands, while Louisiana Waterthrushes are in forested stream areas. 2. Behavior: Look for the Black Tern's flocking and buoyant flight versus the waterthrush's solitary, tail-wagging behavior. 3. Plumage: Note the Black Tern's dark plumage compared to the waterthrush's streaked underparts. 4. Vocalization: Listen for the waterthrush's loud song, absent in the Black Tern.
