Most flies used in fly fishing incorporate some sort of feathers, but that's usually to imitate an insect or fish. The largest "terrestrial" that I've ever imitated is a mouse (the fly consisted of some other type of non-mouse fur--rabbit and deer). This is typically done at night, and it's a lot of fun.

I know people who have seen fish eat ducklings, and I've seen fish try to grab damselflies out of the branches of trees. But watching a fish grab an entire pigeon off of the shore is pretty cool.

Yeah, I'm a fly fisherman myself, so my response was partly tongue in cheek.

I had a vole-type fly as well, but never used it in anger. Biggest for me would be a fry/minnow imitation.

People always talk about pike taking ducklings, or duck's feet, but I agree saying a pigeon being taken would be cool.

I've seen lots of Bass and Pike go for ducks :)

As a note, the vole or mice flies are fantastic for Trout streams, Bass and Pike. Big rainbows or Brown Trout will snap up a mouse fly on the surface - draw it past with a very rapid staccato motion to make waves on the surface.

Then watch their wakes rocket to the fly. Total blast :)

I wonder if you could fish for sharks with a fake floating duck (or pelican or whatever).

I've seen shows where they "fish" for sharks with seal decoys (no hooks in them though).

I'm tempted to try.
