There was a flutter in the bushes and a small bird with yellow flashes flew up to a branch. A Yellow-Rumped Warbler, from what I can tell from online and printed bird guides.
(What a great name! There is something magical about learning to differentiate one bird or flower or bee from another, even if my guesses at times may be wrong...)
In any case, it vanished before I could get another picture, so this twig-sheltered image is the best I've got.
As for that odd coloured sky effect, that's the blur my lens made of the fall-tinged orange and yellow leaves — and pink branches — in the background.
What is this? From its size, shape and colours — especially that large yellow flash on its back and the side flash by its wing — I think this is a Yellow-Rumped Warbler.
