We recently have been seeing a Rose-breasted Grosbeak female at our feeders. We have also been seeing a male Rose-breasted Grosbeak. They must be breeding. She's not as knock-your-socks-off brilliantly colored as the male. Then again, he does not have to sit on the nest, as she does, a sitting duck for any predator. So, for her, it's much better to have subtle, more camouflaged colors.
