My Nikon D300 camera stores the focus distance within the picture. With this you know how far away your bird was. It won't be too hard to calculate the size of the bird. For instance, you can take an object of known size and take a picture with the same lens from the same distance and compare the size of this object in the image, with the size of the bird in the image.
