Mystery oil spills off the Dutch coast affected colonial, adult Lesser Black-backed Gulls prior to and within the breeding season. From colour-ringed individuals, it was demonstrated that most oiled birds survived and were clean within a few weeks and often bred successfully. Further evidence of self-cleaning properties of Larus-gulls is provided from a long-term colour-ringing project (1984-2009). In total 46 birds were reported 'oiled', two died, but the majority cleaned itself and survived for up to 20 years after being oiled. From colour-ring data and 30 years of beached bird surveys (1980-2010) it is demonstrated that the effects of chronic oil pollution is larger in winter than in summer; a reflection of seasonal differences in exposure and environmental conditions. The self-cleaning properties of gulls are such that long-term survival is not necessarily jeopardized and even in a breeding season, not all is lost in case of a spill.
荷兰海岸发生的神秘石油泄漏事件，在繁殖季节前后影响了未成年的黑背鸥。从带有彩色环的个体来看，大多数被石油污染的鸟类在数周内就能幸存并清理干净，而且通常能够成功繁殖。Larus 海鸥具有自我清洁特性的进一步证据来自一个长期的彩色环标记项目（1984-2009 年）。总共有 46 只鸟被报告“被油污染”，其中有两只死亡，但大多数鸟都能自我清理并在被污染后存活了长达 20 年。从彩色环数据和 30 年的海滩鸟类调查（1980-2010 年）来看，冬季慢性石油污染的影响比夏季更大；这反映了季节性暴露和环境条件的差异。海鸥具有自我清洁特性，因此长期生存不一定受到威胁，即使在繁殖季节，发生泄漏事件也不会失去一切。
