Подробности наблюдения
Immature Black Tern with Forester Terns & Gull-billed Terns in southwest pool. See photo for identifying field marks such as black pattern on top of head and behind eye, bill size, color & shape, blackish patch (spur) in front of wing and white lesser coverts (?) at top of wing seen when bird is on ground. Bird looked essentially like the juvie depiction in Sibley's guide. Ruled out non-breeding adult, which can look similar, due to time of year.
