My father is an avid nature lover.  His last bird feeder was taken by the squirrels.  The Oriolefest Oriole Bird Feeder is really cool in that it allows you to truly bird watch.  We have seen all kinds of different birds coming to inspect the feeder.  Since it is open you can get a good full view of the birds.  This is easy to put together and is way less expensive than buying regular bird seeds that other animals enjoy too.
