Aha, I can hear some of you say, this can't be a Blackbird because it's brown!
This is the female bird, her colouring will give her some camouflage protection when she's sitting on a nest.
The males are black and have a bright yellow beak.
These birds are quite big, about 24cm long (9½ inches)
not quite as big as a pigeon. More facts - here -
on the British Trust for Ornithology site.
As with almost all my garden bird pictures, this one is taken through a window, looking into our garden..
