Erithacus rubecula
AKA: European robin
The UK's favourite bird - with its bright red breast it is familar throughout the year and especially at Christmas! Males and females look identical, and young birds have no red breast and are spotted with golden brown. Robins sing nearly all year round and despite their cute appearance, they are aggressively territorial and are quick to drive away intruders. They will sing at night next to street lights.
