The
number or Blackbirds substantially increases in the UK in the winter months, due
to large migrant flocks arriving from the Continent.

These
are told from our resident birds by the colour of their bills.
The
resident adult birds have bright orange-yellow bills, but the adult migrants'
bills are dark.
This
morning (2nd Dec 2011) I visited Darley and
Nutwood LNR, where I would normally expect to see some 4-6 birds, but to-day I
counted over 40 birds, the majority being migrants with dark/black bills.
 Male: Glossy black plumage with orange-yellow bill.  Female: Dark brown plumage with faintly spotted breast
