Title: Maybe Squirrel proof but not large bird proof
Review: I purchased this feeder not so much to deter squirrels but to keep the larger birds from depleting the seed supply so quickly. However, even though I have the feeder set on the lightest setting, I have seen the grackles and blue jays land on the perches and the perches do not close the feeder. Everytime I go out to press on the perch, it appears to "stick" the first time I press down on it - which is apparently enough to keep the perch from closing the feed holes. Even if the perch closed, the birds can easily just hang onto the sides edges of the feeder and get to the seed. So, I assume that it is squirrel proof but not always large bird proof.
