On the hummingbird feeder. This is the first time I've seen a robin do this--they usually perch on the metal pole that holds the hummingbird feeder.
This is a foam target deer we use for practicing our bow & arrow shooting. It's close to my little pond where the robins like to bathe and then they fly over to perch on the deer's head (or sometimes the deer's butt) to dry off their feathers.
On top of a tomato cage in the garden.
On top of the "lawn boulder" (after the deer head, this seems to be their most favorite perching spot in the backyard).
What's the most unusual thing you've seen a robin perching on?
