Seabird sightings from offshore Republic of Congo

Original provider: Marijke N. de Boer Dataset credits: Marijke N. de Boer Abstract: The occurrence of seabirds in Congo waters is poorly known and therefore we recorded the daily presence of seabirds during a geophysical survey. The most commonly encountered seabird species included small migratory terns: Arctic Tern (Sterna paradisaea), Common Tern (Sterna hirundo), West African Crested Tern (Thalasseus albididorsalis) and Wilson’s storm-petrel (Oceanites oceanicus). Parasitic Jaeger (Stercorarius parasiticus) and Sooty Shearwater (Ardenna grisea) were also recorded. Unusual visits of a land birds were also recorded, including green-backed (mangrove) heron (Butorides striata), an African Paradise flycatcher (Terpsiphone viridis) and an African Green Pigeon (Treron calvus).原始提供方：Marijke N. de Boer 数据集致谢：Marijke N. de Boer 摘要：刚果海域海鸟的出现情况鲜为人知，因此我们在地球物理勘探期间对海鸟的每日出现情况进行了观测记录。本次调查中最为常见的海鸟物种包括小型迁徙燕鸥：北极燕鸥（Arctic Tern, Sterna paradisaea）、普通燕鸥（Common Tern, Sterna hirundo）、西非凤头燕鸥（West African Crested Tern, Thalasseus albididorsalis）以及威尔逊风暴海燕（Wilson’s storm-petrel, Oceanites oceanicus）。此外还记录到了寄生贼鸥（Parasitic Jaeger, Stercorarius parasiticus）和灰剪水鹱（Sooty Shearwater, Ardenna grisea）。本次调查同时记录到了异常到访的陆鸟，包括绿背（红树林）鹭（green-backed (mangrove) heron, Butorides striata）、非洲寿带鸟（African Paradise flycatcher, Terpsiphone viridis）以及非洲绿鸠（African Green Pigeon, Treron calvus）。
