This was one of the coolest things I have done in awhile. My Grandpa had told me last year that there was a spot in a local park where the chickadees will feed off of your hand. I was instantly excited and couldn't wait until it opened again the following year.
I mean, it's quite rare and special to hand feed a bird in the middle of the woods ya know? There was a decent amount of waiting and my arm went numb a couple times, but it was such a thrill when they actually landed.
Here's a link to the park if you're interested in going - West Woods.
