Detalhes da observação
generally rare/absent on LI this past Jan-Feb; hints of migration during Mar; unmistakable influx recently; only one of these four was unambiguously fully adult, with large white primary tips; two others seemed to lack immature coverts but showed small/worn white primary tips, and one of these showed excess black markings on bill; one was unambiguously third-summer (fourth CY), with immature-patterned outer primaries and some retained immature coverts; lots of calling--kowps and trumpets; in the audio included, it is not always easy to distinguish LBBG from GBBG (lower pitch) and HERG (higher ptich and clearer), so this link to video assists in aligning calls: https://flic.kr/p/Tpf5XE ph., vid., aud.
