Calls from a pair of Ross's Gulls (one adult and one SY bird); most of the louder gull vocalizations are from the displaying adult, which flew a 15 meter circle around the SY bird (which was standing on a small island in a tundra pool) before landing with its tail cocked up as it called intensely (the rapid sequences that seem to mirror the "long calls" of other calls). During the "long call" sequences from the adult member of the pair, the immature member of the pair made low moaning/ whistling calls. A third Ross's Gull (adult) was nearby but was not involved in this recording.
观察细节
*spectacular; a continuing pair (adult + SY; behavior suggests the adult is a male and the SY bird a female) along with an interloper adult (presumably a male based on its behavior); wild courtship/ mate-guarding flights with all three birds (the interloper chased the SY bird while the paired adult tried to exclude the interloper); audio and photos
