I believe a yellow-rumped warbler.
Could be a Audubon's Warbler
I'm no birder and just guessing, is it a goldfinch?
That's the male Audubon's, great job. If you keep killing the House Sparrows, you'll see more variety every year. The House Sparrows are parasitic, they kick other birds young out of their nest's and lay their own egg's in the nest, nasty buggar's.
What color was the body? Gray could be house finch, black possibly red breasted sap sucker and yellow, western tanager. Not too many red-headed birds beyond that, the pine grosbeak and purple finch are pretty much all red, as well as the red crossbill.
We don't kill any starlings or house sparrows. We've got a big backyard with lots of different birds. I suppose, most birds were invasive at one time. There's really not much you can do about birds flying into your area.
