the first bird and head-on composite clearly a first-winter male with an obvious pale iris but is the second bird (6-8 down) a first-winter male as well? it was too dark and not close enough to resolve iris colour but a dramatic difference in underwing pattern visible in photos -- two of the birds roosting at Blacktoft and passing through Alkborough
