I see 14 in total, excluding the original bird in the image.
Of the 14 are 5 of them birds, plus the main image making it 6.
Then there's a snake in the bottom left, a mole bottom centre, a mouse near the bottom right corner, a butterfly in bottom right corner.
Above the butterfly is a pig.
Above the snake is a fish, a grasshopper, and a snail in that bunching on the twig.
In the top right corner is a jellyfish.
