This "tremble-foot" behavior is fairly common in wintering Hermit thrushes.
I rarely see it employed among my wintering population of the species until
after the berry fruits are no longer available. When performing this quirky
flush-and-eat routine, Hermit thrushes will stand very erect with neck
stretched. They appear to me to stand perfectly still except for the
trembling
foot. Neat stuff.
