Abstract

Abstract. Sandwich (Thalasseus sandvicensis), Common (Sterna hirundo), and Roseate Terns (S. dougallii) made overland flights from a breeding site in Brittany (northwest France) to forage in a semi-enclosed basin (Rade de Brest) ∼30 km away in 1976 and 1978. The foraging area was contaminated with polychlorinated biphenyls (PCBs) and high levels of PCBs were detected in several tern eggs. Levels of PCBs in tern eggs were sufficiently high to have caused adverse effects on reproduction. PCBs should be considered as potential contributory causes of declines in tern populations in the 1960s–1970s, in addition to other known causes including predation and trapping in the winter quarters.

20世纪70年代法国西北部燕鸥的陆路飞行及其对多氯联苯的高度暴露

摘要1976年和1978年，三明治燕鸥(Thalasseus sandvicensis)、普通燕鸥(Sterna hirundo)和玫瑰燕鸥(S. dougallii)从布列塔尼(法国西北部)的一个繁殖地经陆地飞行到约30公里外的半封闭盆地(Rade de Brest)觅食。采食区多氯联苯污染严重，多颗燕鸥卵中多氯联苯含量较高。燕鸥卵中的多氯联苯含量高到足以对繁殖造成不利影响。多氯联苯应被认为是20世纪60年代至70年代燕鸥种群数量下降的潜在原因，此外还有其他已知原因，包括冬季栖息地的捕食和诱捕。
