This is what one of my bird feeders looks like. I put the peanut butter flavored suet (non-sticky) in the little suet holders, but I break them so they don't go above the top of the cage.
The other night, I was enjoying a beverage on my deck. It was very dark. I heard this, "clank ... clank ... clank ..." over and over, coming from near my shed. Not gonna lie .. I was a little scared.
Well, that's where this bird feeder is. Suddenly, I see this enormous doe walk around the front of the shed and go into my neighbor's yard.
I checked the feeder the next morning and the suet cakes were still intact. She must have been licking them, lol.
Nature is great stuff.
