胶囊大胆定义了动物在捕食者面前愿意冒险的程度。在繁殖季节的后期，但不是早期，以色列雏鸟仓鸮显示较大的黑色羽毛斑点更温顺，假装死亡的时间更长，并且在处理时比斑点较小的雏鸟呼吸频率更低。较大的斑点繁殖女性不太温顺，如果重，但更更温顺，如果轻。因此，性格（大胆与胆小）和黑色素为基础的颜色之间的协变是有条件的环境因素。
Capsule Boldness defines the extent to which animals are willing to take risks in the presence of a predator. Late, but not early, in the breeding season, Israeli nestling Barn Owls displaying larger black feather spots were more docile, feigned death longer and had a lower breathing rate when handled than smaller-spotted nestlings. Larger-spotted breeding females were less docile if heavy but more more docile if light. The covariation between personality (boldness vs. timid) and melanin-based colouration is therefore conditional on environmental factors.
