So this is probably not related to this group but I have no idea where else it would go lol

When I got home today from a birthday party, I noticed a red cardinal sitting in front of my garage not moving. When I got closer, he turned his head and looked at me. He wouldn't fly or move though. He did let me pick him up and I tried to put him in a tree but he fell out lol He did eventually climb up my shoulder and fly back to the tree though. Anyone have any idea why he would do this? I'm no bird expert lol
