yep...what BLB said. Northern Flickers have a flight pattern like that...but the bird in the pic doesnt really look like one to me.I think its a bird in mid flap going straight away from the cam.
Not much of an ornithologist, but some birds have an odd cadence to the wing beat where they flap with the wings nearly folded to the body on the finish stroke.
Looks like a hen pheasant to me but maybe you're too far north for that.I was guessing a turkey flying exactly over the sun with its beard hanging below. Otherwise some new kind of drone...
