I think you have to be very brave to say whether this is a male or a female, as they are identical (unless you've got one in the hand and can turn it upside-down). With my Packham hat on, I'd say that the photos are not quite true in colour - look at the colour of the feet - which is hard to avoid on gloomy days.
I don't think incubating eggs is really relevant as, like most small birds, they sit deep in the nest with their undersides invisible.
However, it's lovely to have them peeping in through the window at you. We've just had the reappearance of a Song Thrush in our garden - bit optimistic to say it's the first sign of spring, though!
