foot-tapping in waders

[(John Leonard)]

I have seen this behaviour in South Island Pied Oystercatchers on short
grass in an urban park in Dunedin, SI. It was after a period of rain, and I
surmised that the birds, all of which in the flock were doing this, were
trying to persuade the earthworms that the rain was still continuing.
