There were a few alarms when I first put the new perch in. But Decaffeinated, who, at a porky 20 grams, knows a tasty seed when she sees one, was daintily snacking just a few minutes later. Several Finsters have been observed on the perch, snacking on the F.A.D. throughout the day, sometimes more than one bird at a time. Unfortunately, none of the birds have touched the cuttlefish bone.
