When I wanted to walk to my mailbox and stepped through the door, right in front of me sat a fainting Blue-tit in shock.
He might have crashed against the glass-window or it was the heat, because today its extremely hot.
I took him out of the hot sun into some shadow. I tried to give him some water with a dropper and put his feet in a bit of water as well to help him cool down.
Finally he flew away, so glad he did!
