outer part; eye reddish; breast black with gloss; flanks and back pale
ash-grey, appearing whitish in strong light; stern black. In flight, medium
grey upperwing-coverts and pale grey wing-bar give the bird a rather
washed-out, pale appearance.

dark head marks, along with head/bill profile, often best clue: diffuse pale

which reaches lower base of bill; bill with a narrow, dull pale band across outer
part (winter), or appearing all dark (summer). Eye rufous-brown.
