Found injured Hummingbird and kept in shoe box at night. Morning kept in semi sun to keep warm and it showed some signs of life. I fed 1:4 sugar in water first with a cotton bud but not sure it was comfortable- saw tongue couple of times, so got a spoon and it really dug in. But then it’s tongue seemed to stuck out even when I moved spoon away and it seemed to struggle. I got some plain water and a fresh bud to wet and hopefully unstick it’s tongue and when I came back it had died. I don’t understand what I did wrong and why it’s tongue should get stuck out. Any ideas?
