New York - the ultimate in man-made environments and the last place to make a wildlife film... or is it?
There are, in fact, parakeets nesting in air-conditioners and Western jack-rabbits living alongside the jets at Kennedy Airport; so it's not just the usual opportunists like squirrels and pigeons who have found their niches.
