If you are a birdwatcher, you will love Central Park. There is a 37-acre area called The Ramble (just south of the Belvedere, shown on the maps on signposts and free from Central Park information booths), full of wildlife.
Take binoculars and a camera, and try to find a stream as this is where the birds feed and bathe.
Only starlings and sparrows will be familiar to Europeans.
Bird books are available from Borders etc., otherwise you won't know what you're seeing. We enjoyed it for three hours and never made it to the Met that day!
More info from the park Conservancy office in the Belvedere.
Central Park, roughly at 76th St level
