In 1923, a Japanese professor published a study in which he described a correlation between the cries of his neighbour's pheasant and noticeable tremors. In seven cases, the pheasant cried well before the ground noticeably shook, and in four cases before tremors that were only picked up by sensitive instruments. In five cases, the pheasant crowed during the first noticeable tremors and in another five it cried too late or not at all. In the 11 cases when the pheasant cried before the tremor, it may have felt the first waves of a quake: P (primary) waves, which travel slightly faster than the S (secondary) waves accompanying tremors.
