JPMyeos 1979 Luscinia svecica Willow Creek (8,40) Meade River Sound System, Atkasook, Alaskan 6 June 2200 hrs > walked to end of runway after learning from Shuford + Eeven that it had been singing there earlier. After 15 minutes I heard it soaring above Willow Creek: 30m Sings in falling descent {10m} slight path The ? also sang while perched on a twig or the ground. Their mimicry is positively astonishing. To begin, the ? I listened to does an incredible & Calidris melanotos churr, interspersing that note with others while rising to the apex before it falls. Overall the song sounds like a California thrasher [psychokinetic mimicry ?]. The ? sings beside the ?, or when she is on a nearby bush. Perched on the ground ? he flicks + fans his tail + puffs out the red spot on the blue throat. This male imitates: Pluvialis squatarola, Calidris melanotos, Stercorarius longicaudus, Motacilla flava Acanthis sp., and Calcarius lapponicus. The quality of its imitations are positively mind boggling. I taped a series when it gave at least the ? C. melanotos churr and a Pluvialis squatarola. 9 June 1200 found ? and ? Luscinia on Willow Creek again. Imitating same set of species. Good photos (15,39), Bluff beside Meade River, Atkasook 1430 found another with Chris Siwath. This one imitated Pluvialis squatarola and P. dominica (nest alarm display), ? Calidris melanotos, Motacilla flava, Acanthis sp., and Calcarius lapponicus
