20世纪60年代和70年代，东苏格兰五月岛的海雀和海鸠数量大幅增加。这些增长在1980年代停止。繁殖成功率仍然很高，但成年海雀的存活率有所下降，可能还有未成熟的海雀，而在生命的第一个冬天恢复的环海鸠数量有所增加。这些变化似乎与鲱鱼数量和分布的变化有关。
The populations of puffins and guillemots on the Isle of May, East Scotland increased greatly during the 1960s and 1970s. These increases ceased in the 1980s. Breeding success remained high but there were declines in the survival rates of adult, and possibly also immature, puffins and an increase in the number of ringed guillemots recovered in the first winter of life. These changes appeared to be linked with a change in the number and distribution of sprats.
