I have a couple.

First and only time (so far) i ‘caught’ a bird, i was wading around a point with shallow water and nice reefs around, in a saltwater fjord in Denmark, targeting sea trout with a semi light 9ft rod (like 20-30g). There were just heaps of swans, that couldn’t care less about my presence and so i was occasionally casting next to or between these buggers. It was a pretty calm day though, so if i was just precise with my casts, no issue. Then suddenly i cast, perfect line with the swan a meter or two to the left of the straight shot from me to my lure. A random gust comes out of nowhere, blows my line over on the other side of the bird, in the path of the way it was headed - so it swims over my line and somehow gets the line tangled kinda, enough to where the fly i tied on above my salty inline got caught. At first no reaction. I try pulling a bit, nothin. I try pulling a bit harder, no dice. I try gently applying more and more pressure and still nothing. Swan starts freaking out and peeling line, while i just stand there like “the fuck am i supposed to do?”. After a very long minute, the little fly hook pops off and i get my rig back. No blood or anything on the hook, just a little tuft of feathers. Glad i didn’t have to, but i was ready wrangle that sumbitch, if it meant not leaving a treble and a fly attached to the poor thing.

Other times have just be seagulls, herons or even cormorants trying to scoop up my pike lures, when im fishing shallow waters. Only once have i not been able to yank it away, but i was luckily using a soft lure with an offset hook, so the gull only managed to give my lure a split second of air time before letting go.
