This morning while Gwen was puttering in the back yard, a juvenile bluejay landed on the ground, near our back door. He looked like he had his flight feathers, but the feathers on his head were still downy. He wouldn’t or more likely couldn’t fly away; he could hop, but mostly stayed put.
Not knowing what else to do, we set out a shallow pan of water for him. He made no effort to get away from us, but did hop into the pan of water.
About an hour later, I looked in on him. He was still in roughly the same spot. I refilled the pan of water and set it next to him. He looked at me and opened and closed his beak a few times as if silently chirping or begging for food. He flapped his wings for a moment and flipped over on his back. The nictitating membranes blinked across his eyes and he died.
When we looked at his corpse, we saw a spot on his back where he had been attacked.
