Description:
Blackbirds are
so familiar that they should present no difficulties in identification.
Adult males are black in colour and in full breeding plumage
show yellow eye-rings and bright bills. Adult males with duller
bills and lacking yellow eye-rings at the start of the breeding
season will be winter visitors, probably about to depart back
to their own breeding grounds (where they will then develop
the full breeding plumage). Females are umber or rufous brown
in colour, often with a pale throat patch. Juveniles are a
warm rufous brown, with spotted plumage.
Ecology & Behaviour:
Much of what
we know about Blackbirds comes from studies carried out in
suburban parks and gardens. Blackbirds seem particularly at
home in these habitats, perhaps helped by the ability to nest
in a range of different situations. They can often be seen
feeding on lawns and flower beds. Blackbirds are territorial
in nature and defend areas holding suitable nest sites and
feeding opportunities.
During the autumn,
hordes of Blackbirds from Norway, Sweden and as far east as
Finland, come to spend the winter with us. We know this from
the work of bird ringers. By fitting birds with rings it is
possible to identify where they have come from. During the
winter these winter will forage alongside our resident birds,
making use of the windfall apples and other food put out to
help them through the cold winter months.
