观察细节
probably code-able to M (well-spaced males singing from prominent perches from the spruce-line up to the summit). A very early mild spring this year (only patches of snow remaining in some of the deep gullies) as well as numerous warm southerly flight nights likely combined to bring locals up early; but given that multiple other local warbler spp. were foraging in a mobile mixed flock further down the mountain, I can't be sure these blackpolls were resident.
