After months of hanging out front the suet was untouched by squirrels - until this one figured out ow to jump from a Japanese red maple to another bracket holding another suet feeder, from which it traveled to this one! Hard to beat a determined squirrel.
(Nice to see the advantage of a full frame camera put to use in blurring the background. It has been hard for me to get used to the shallower depth of field with this, the first full-frame camera I've ever used.)
