Last Year’s Young Female (?)

She looks familiar. I think she may be one of the two females I saw hatched and grown to maturity last year, before their nest was destroyed.  Now – if I’m right – she’s back in the neighborhood. I spotted her today with another female (perhaps her mother, because the other bird is obviously more mature judging from her size and darker color). They were hanging out in a nest very near last year’s destroyed nest, perhaps both looking for a mate.
