摘　　要：掌握竞争关系下鸟类繁殖生态,有利于加强鸟类繁殖地的管理,促进鸟类资源的保护。为此,于2020年6~7月间,在广东海丰鸟类省级自然保护区大湖东分区选取了13个环颈鸻(Charadrius alexandernus)繁殖巢,17个白额燕鸥(Sterna albifrons)繁殖巢,探讨了种间竞争关系对两种鸟类繁殖生态的影响。结果表明:①在巢址选择方面,它们均于地面营巢,白额燕鸥巢址周围较环颈鸻巢址更为裸露,环颈鸻多选择可以就近捕食的地方,白额燕鸥对于巢址选择则相对要求较低;②环颈鸻的种内巢间距较大,白额燕鸥的种内巢间距较小,环颈鸻与白额燕鸥之间的巢间距最大为143.62 m,最小的仅为8.93 m。Grasping bird breeding ecology under competitive relations is beneficial to the management of bird breeding sites and the protection of bird resources.To this end,13 breeding nests of Charadrius alexandernus and 17 breeding nests of Sterna albifrons in the Dahu East Division of Haifeng Bird Nature Reserve in Guangdong Province from June to July 2020 were selected to explore the effects of interspecific competition on the reproductive ecology of two species of birds.The results showed that:①In terms of nesting site selection,S.albifrons nested on the ground.Compared with C.alexandernus,the C.alexandernus chose more nearby nesting sites.S.albifron had lower nesting site selection requirements,②The nest spacing between C.alexandernus and S.albifron was larger than that between Charadrius alexandernus and Sterna albifron.The nest spacing between Charadrius alexandernus and Sterna albifron was 143.62m at the maximum and 8.93m at the minimum.
