I caught a swan once, it died. The landowner actually thanked me for it, they chase her around her own yard (she's 85). I've also had a Great Horned Owl go after my frog at night. That's scary.

 

We caught two great blue herons on a couple limb lines once. Needless to say we no longer used limb lines in shallow clear water after that

I don't know how you managed that. I have witnessed those birds "eat" a LOT of goose shells and keep on trucking!

Mute swans of course, on the nuisance species list with pigeons and starlings.

I was fishing a pond in the middle of my city that was stocked with bass. I was throwing a squarebill in the middle of the pond. I get slammed by what I thought was a nice bass. I set hook and started reeling. Seeing my line run for the surface I thought I was about to see a big ole mouth and gills, boy was I wrong. To my surprise, a big ole mallard came flying out of the water with my crankbait in its mouth! My buddies just died laughing! I had no clue what to do! I ended up cutting my line pretty quick and the stretch just sling shotted the line towards the duck and wrapped it. The duck fell back into the pond and was struggling. It ended up getting the front hook in its foot and looked like it was going to drown. I swam out and got the duck, my buddy held the duck as I got the hooks out of it. It was like the duck knew we were helping it and stayed calm the entire time! One of the strangest stories of my life. I wish I had the old flip phone with the pictures still!!

In the last two days I've caught 1 HUGE snapping turtle and a bullfrog, both on senkos! I was bombarded by turtles going after my top water frog this morning. I couldn't make a full retrieve without them going for it 

Had a duck grab a plastic worm when I was a kid. Actually took off flying with my worm in its beak! Scared the bejeebers out of me that I was gonna lose my rod and reel. Fortunately it pulled loose about the time the line got tight. That was the last time I ever cast into a bunch of ducks!?
