Tatsuya Shiozaki (Graduate School of Environmental Studies, Nagoya University, Japan) and colleagues have published in Japanese in the Japanese Journal of Ornithology on a feral cat Felis catus entering the metre-long burrow of a Streaked Shearwater Calonectris leucomelas and removing the chick. The article also describes egg predation by a Large-billed Crow Corvus macrorhynchos and chick predation by a Japanese Rat Snake Elaphe climacophora.
