Taken at 8.10 am when bird & vegetation very wet. Pro'-Blyth's features would seem to include the bulging fore-supercilium, fairly plain tertials, concolorous wings, mantle and rump with no warm tones, brownish-grey legs, short-looking primary projection. Other interpretations might be possible (eye ring strength?)... Unadjusted image.
Canon, 300 mm, handheld.
