In May 2021, we opportunistically observed one Eurasian jay () attacking an adult incubating Japanese tit () and depredating nine tit eggs at a nest box where a woodpecker had greatly enlarged the entrance. After the predation event, the Japanese tits abandoned the nest. We recommend that when using artificial nest boxes to protect hole-nesting birds, the appropriate entrance size should be proportional to the body size of the target species. This observation gives us a better understanding of the potential predators of secondary hole-nesting birds.
2021年5月，我们偶然观察到一只欧亚松鸦攻击了一只正在孵蛋的成年日本山雀，并在一个啄木鸟将入口大幅扩大的巢箱中掠食了9枚山雀蛋。捕食事件发生后，日本山雀放弃了这个巢穴。我们建议，在使用人工巢箱保护洞巢鸟类时，合适的入口大小应与目标物种的体型成比例。这一观察结果让我们对次生洞巢鸟类的潜在捕食者有了更好的了解。
