Re: Bird Co-operation in hunting

The hawk in question is the Harris Hawk (also known as the Bay-winged Hawk)
found in the southwestern USA.  Cooperative hunting by extended family
groups has been chiefly documented in SE Arizona both in the literature and
on video/film. I have a copy of the video mentioned below and it is
"absolutely extraordinary."

Another example of fascinating cooperative hunting activity by birds is the
cooperative fishing of pelicans which has also been shown on several
different nature documentaries through the years and pictured in books.

Have a good day!
