voles or lemmings have some sort of way to do that "walk on water" trick .I have seen it more than once, but never saw one try to cross too wide a creek, so I do not know how far they can stay on top like that.
I used to think that when I witnessed a owl or hawk make a kill in front of me, that I was in the right place at the right time, but once we were hunting a grassy alpine island for deer and there must have been thousands of voles on this island, as we were kicking them up out of the moss and short grass constantly . there were also about twenty or thirty hawks hunting the voles around us. The wind was pretty steady and the hawks were hunting by hovering over a spot and waiting for a vole to make a move. By the time we finished driving the island for deer, some hawks were lined up hovering only a few feet off our shoulder. sometimes we could have almost reached out to touch them. when we kicked up a vole , the hawks would swoop in to nail the it, only a few feet in front of us. A tactic I realized I had seen before, but not been aware of how I was being used.
