摘要
2007年5月至2010年3月,对陕西黄河湿地水鸟进行了将近3年的研究.通过野外实地观察、拍摄照片、走访群众、查阅资料,发现陕西黄河湿地有水鸟7目15科45种,其中国家一级保护动物(水鸟)3种,国家二级保护动物(水鸟)4种,陕西省重点保护水鸟9种.在45种水鸟中有24种以鱼类为食,有10种水鸟在觅食其它食物的同时也觅食鱼类;研究发现水鸟觅食的是小型鱼类和体弱多病鱼类,且小杂鱼居多.
We conducted a three-year investigation of waterbirds from May 2007 to March 2010. Based on field observation, photographs, visiting the residents and documents, the results are as the following： 45 species recorded belong to 7 orders and 15 families. Of these species, 3 species are identified as I key state-protected avian species, 4 species as II key state-protected avian species and 9 species as key provincial-protected avian species. Of these species, 24 species mainly feed on fish, and 10 species occasionally feed on fish. Fishes fed by waterbirds are small or unhealthy ones, and most of those are wild species.
