The male of this species is coloured a very bright blue during mating season which is late winter-Spring. The females are brown and the young are also brown but often with mottled colouring and blue/black tails. They have an interesting and cute (I think) call sound.
While I was in the garden a couple of weekends ago I noticed a family of wrens had come out to play. The birdbath was full from the recent rain and so some decided to have a bath too.
