I love this fly thru bird feeder from Birds Choice.  It's nicely designed with tree shapes holding up the roof.  Pretty light green color that fits in well in  my yard.  I'm especially happy that it's made with primarily recycled plastic - and the plastic isn't flimsy at all, but about a half in thick.  The roof lifts off for easy cleaning and the metal bottom of the feeder is perforated to help keep the seed dry.  This feeder is so sturdy and well made that I expect it will last for  many years.
