Ok...so I believe Google helped me ID this as a zebra finch. Looks like it's native to Australia! Must be someone's escaped pet? Wonder how he's doing today? He's a long way from home here in NE FL.

BINGO!! We just found it in the bird book. I'd never heard of it before. How did you find it so fast? https://www.allaboutbirds.org/guide/Brown_Creeper/id

Whitelacey.......this is so funny! I looked out my kitchen window, and on the ground under my suet feeder was a bird that looked just like what you described. Very black head and back with white stripes on the wings, and very white chest and abdomen. Of course, just as I turned to get my camera, it flew off. I should have stayed and observed more instead! As it flew off, it had pretty obvious white wing stripes. My first inclination was a juvenile male towhee.....since we have lots of towhees around. I saw no brown. I'll keep my eye out and my camera close-by........but I immediately thought of you and wondered if, now, I will be driven crazy too. hahaha What caught my eye as it was flying up to a tree was the white on it's wings, which made me think of a red-headed woodpecker. I looked up juvenile redheaded woodpecker and some of the pics looked like it, except mostly in the pics, their heads were grayish. Oh well.....hopefully I'll see it again!

Its a duck, a green wing teal I believe. Birds have a number of predators, small and medium mammals, other birds, reptiles. Could be a hawk or owl, or a cat or fox or raccoon. Squirrels even will raid nests I believe.
