Big baby, little Momma

We saw this young Brown-headed Cowbird (?) being fed by a Sparrow (Clay-coloured?) on a walk in the rain this afternoon at Griffth Woods. Had to shoot into the sun and it's not as sharp - or as close, LOL - as I would have liked, but it was interesting to watch as this hard-worked Sparrow fed her huge, adopted baby! Hats off to these gullible small birds who accept the offspring of parents who lay their eggs in other birds' nests! Still haven't figured out how to adjust the colour and brightness on my monitor, so please bear with me if this photo appears too light or too dark. I know the right button to press, but then can't move in the direction of any arrows. At the moment, I can't tell what is what on my screen, which is frustrating, LOL!
