二名法 Papasula abbotti(Ridgway, 1893) 粉嘴鰹鳥（學名：Papasula abbotti），又名阿波特鰹鳥，是一種瀕危的鰹鳥。牠們只分佈在聖誕島，是阿波特鰹鳥屬唯一種。其名字是紀念於1892年在聖母升天島發現牠們的William Louis Abbott。 目录 1 特徵 2 分佈及棲息地 3 行為 3.1 繁殖 3.2 食性 4 保育 5 參考 特徵 粉嘴鰹鳥長約79厘米，重約1.4公斤。牠們是黑白色的，與其他同區內的鰹鳥有明顯分別。牠們到了8歲才能繁殖，每兩年才會繁殖一次，估計壽命達40年。[2] 分佈及棲息地 粉嘴鰹鳥以往也會在印度洋島嶼上繁殖，但現只會在聖誕島上繁殖。牠們只會在聖誕島附近的海域上出沒。在南太平洋曾發現牠們的化石。 行為 繁殖 粉嘴鰹鳥在雨林之內築巢，約於6月或7月就會產蛋，每次只產一隻蛋。雛鳥成長得很慢，要約半年後才可以飛行，需要父母照顧約230天。[2][3] 食性 粉嘴鰹鳥吃魚類及魷魚，雛鳥則會吃牠們反芻出來的食物。[2] 保育 大部份粉嘴鰹鳥的棲息地都被1960年代及1970年代的磷礦所破壞，牠們現正處於瀕危狀況。牠們的數量估計只有約3000隻，且正在下降。在聖誕島，颱風、棲息地減少及長角捷蟻都是牠們生存的威脅。在海上，過度捕漁及海洋污染都令牠們的數量下降。[4][5] 參考 维基共享资源中相关的多媒体资源：粉嘴鰹鳥 ^ Papasula abbotti.

Abbott's booby (Papasula abbotti) is an endangered seabird of the sulid family, which includes gannets and boobies. It is a large booby and is placed within its own monotypic genus. It was first identified from a specimen collected by William Louis Abbott, who discovered it on Assumption Island in 1892.
Abbott's booby breeds only in a few spots on the Australian territory of Christmas Island in the eastern Indian Ocean, although it formerly had a much wider range. It has white plumage with black markings, and is adapted for long-distance flight. It forages around Christmas Island, often around nutrient-rich oceanic upwellings, although individuals can travel for thousands of kilometres. Pairs mate for life and raise one chick every two or three years, nesting near the top of emergent trees in the rainforest canopy.
