Robins are a bird we commonly associate with winter and Christmas, but why do robins have red breasts? The red colour looks amazing next to white snow, but it also makes the bird a target for predators.
Why do robins have a red breast?
There are several reasons why robins have a red breast:
Male robins with a brighter red breast are thought to be more attractive to female robins.
Older robins have a bigger red area. This is thought to serve as a warning to younger robins to stay off their patch. Robins are a very territorial bird.
