Coyotes were once a western/Great Plains phenomenon, but they have now
spread to the entire contiguous USA, and probably Alaska as well. I
haven't heard of any in Hawaii. They have proven to be pretty
adaptable at living among humans, much more so than have wolves, whose
niche they are now filling. They also raid trash cans and eat the
occasional pet.


I should think in NYC their main diet would be rats - they're slower and
easier to catch than cats or dogs. More plentiful, too.

About 10-15 years ago, resident Canada geese were becoming a nuisance,
overflowing the parks. No one knows for sure, but I believe the resident
coyotes are to be credited with keeping the goose population under
control.
