I have a beef: Birdfeeders
It annoys me when you go looking for a birdfeeder, the feeder says (and looks) like it would be good for the birds you want to have go there, and THEN....
...the birds do not like it. It is too high, the pecking room isn't wide enough in position to the part that contains the food, etc., etc.
What is WRONG with Birdfeeder designers!!!!
