At four weeks old the red rump chick finally has the red feathers for which the species was given common name. There is still a lot of the gray down on his back mixed in and hiding the red.
He also discovered he had wings and started exercising them when we took a trip down the the LA area. Perhaps it was because of the motion of the car as we started up that he flapped to regain his balance and realized that he had wings. And every so often since then he has been exercising those wings.
A few days later, at four weeks old, the chick was well covered with feathers and looked like a three quarters scale version of the adults. He is spending his days in a larger enclosure so he can work on learning to climb, perch and use those wings while he also starts learning how to shell seeds and feed himself.
