The most populated North American city is New York. 

 

Here space is a precious commodity with more than 8 million people fighting for their share. 

 

With so little ground space left, having a garden can require a head for heights. 

 

It’s difficult to imagine any animal getting a foothold in this bustling city. But some do. 

 

The red-tailed hawk is well known in midtown Manhattan. It manages to survive here, because New York has the ultimate in urban gardens, Central Park. This park created in the mid-1800s has become a focal point for wildlife and the people of Manhattan.
