when I was a teenager, before I left for college, I had a cat who was an indoor/outdoor cat, Bummer. He was a goofy kitty, but a mostly good kitty. Loved stalking the deer. And, somehow, he'd always bring me presents. Usually gophers or moles or mice, but twice he brought me live hummingbirds. He never hurt them, just pluck their belly feathers out. Left the wings/tails alone, just plucked the belly feathers out. So I was trying to nurse hummies w/o belly feathers!! They're sooooooooo fragile, so incredibly fragile... but feisty, too. If I didn't hang the feeders up fast enough, they'd be buzzing my head and twittering like mad.. and then they'd perch on my fingers while I was in the process of hanging up the feeders! But much rather have hummies doing that than getting divebombed by rancorous bluejays...
