My old female Lab Cinders never picked up a crow on land, she'd bark at them and push them around. She would water retrieve them, maybe the water took the stink off them. Can't remember her fighting a wounded crow, if she did she made quick work of them. She had an interesting albeit bad habit. If a crippled duck did not fight she would deliver it to my hand alive. If she delivered a dead one that felt kind of spongy ie broken back, it put up a struggle that didn't end well for the duck
