Yesterday I noticed an paleish colored American Robin with a short tail on my porch, it didn’t move as I got closer too it, but then it tried to fly to a nearby tree and ran into it, walked up the roof, and hopped to a branch. It sat there for like 4 hours. She is still going from tree to tree but is constantly panting, having issues flying, and flys loudly. Is she young and learning to fly or is this something I should worry about?
