Nature is constantly evolving to changing conditions. These crows in Japan have learned to use traffic as an ingenious way to crack nuts once too hard for them to open. Furthermore they have learned to use traffic lights to provide a safe passage to the now cracked nuts.
A similar example of this is the dogs of Moscow. Each day, the stray mutts take the subway to the city center to forage for shoarma and other treats, and ride it to the suburbs at night, presumably where the sleeping arrangements are more amenable.
Further to this interesting account of birds getting "street-smart" I came across an article in which researchers learned that city birds have larger brains relative to their body size from a need to survive in the more challenging urban environments.
The study concluded that cities wanting to lure a wider variety of birds for residents to enjoy will have to “create patches of (the birds’) original habitat.” Yet another valid reason for the integration of a rainforest into my project at Centennial Plaza.
