Detalhes da observação
3 birds first noticed feeding on grit on the Old Trail Ridge Road, then 8 birds flew up to a spruce where more were noticed. These might be Edelman spruce? These birds were in the last quarter mile of the road with spruces, right before the timberline ended and entered into the Marmot Point area. Audio attached, see the upside down 'V' ranging between 3-4 on the spectrogram (which it seems is representative of this type).
