NMOS Field Notes 20:3
"Unusual: This possibly overlooked tern, rare in New Mexico, was reported from several areas [this season]. 1 at Burn Lake 9/25-10/2. Sterna terns with unusually deep wingbeats should be examined carefully and the tail pattern (presence or absence of dark outer edges and contrast with rump) should be noted"
