Somewhat analogous is foot-paddling in smaller gulls, which I watched last winter on the Tofino tide flats.

>>> About a month ago I was out at the coast watching some Semipalmated Plovers feeding in the tidal zone. It was really cold and I noticed one bird’s leg shaking — and being rather cold myself I assumed at first it was shivering. Looking over at another one I saw it doing the same thing — and I wondered at that point if it was shaking its leg a part of a probing/feeding behavior. I have not really found any info about this, but it makes sense since their bills are too short to probe the mud it makes sense to me that they’d have an alternative means for sensing or finding snacks.
