In my humble opinion, it's a bird.
I've found the original image, I post a crop here:
The photo was taken with a Nikon COOLPIX L19 (8.0 megapixels) and the original
image size is 2,448 × 3,264, full EXIF data can be found here.
I'd say it was flying in direction right-left, more or less this is what we see:
I could be wrong, just my two €. cents. Happy new year to everyone
I MUST agree with greeneyedleo and internos. This is OBVIOUSLY a bird IMHO. We have seen too many similar and near definite
similar pictures that the probability that it IS a bird is over 99% IMHO. We all wish it was something else but is really is not. Thanks for sharing
though, this is how we all live and learn...
