This morning while out (tardily, the birds would add) filling my feeders, there was a Mountain Chickadee “cheep a cheep” -ing at me. It was in a smallish aspen in my back yard.. I put a handful of seed out toward it in open palm fashion and sidestepped toward the tree. All the while it’s going “cheep a cheep”. It flies to my hand, talking constantly, pecked my thumb several times, looks me in the eye, glances at the food in my hand and flies to the nearby feeder for a seed.
(picture is mine, but not of that instance)
