Ecology and Evolution, Volume 15, Issue 10, October 2025.This paper proposes a ‘relaxed’ point‐count survey method to enhance accessibility and expand geographic coverage by easing these constraints. Surveys can be conducted in diverse locations, including urban areas and travel routes, within flexible timeframes (e.g., 6 h after sunrise or during the evening) and with adaptable spacing between survey points,

野生动物学报, 2007 本研究对笼养白枕鹤行为进行观察记录和分析,结果表明笼养白枕鹤繁殖期行为日活动节律依次为休息（32.15%）、取食（30.02%）、理羽（12.92%）、警戒（12.14%）、游走（8.86%）、繁殖（3.90%）,另外,繁殖期的不同时期、不同性别其行为时间分配都存在一定差异。人为干扰,邻近笼舍内东方白鹳的干扰,以及外界噪音的干扰对笼养白枕鹤繁殖期行为影响十分显著。同时气候条件以及温度变化对笼养白枕鹤总体行为亦存在一定影响。

波斑鸨（Otis undulata macqueenii）繁殖行为研究
, 2002 本文通过对栖息在新疆准噶尔盆地东部木垒波斑鸭野外考察，观测研究其繁殖期间的行为，并对亲鸟昼间活动谱、栖息地选择、繁殖成功率、雏鸟生长发育作了研究。结果表明，波斑鸭在繁殖期表现的各种行为并非杂乱无章，而具有明显的规律性和种（或亚种）的特异性。在繁殖期间，雄鸟的炫耀行为表现得最为明显，雌鸟则具有明显的护巢和护雏行为。繁殖期间，5：30-7:00和18: 30-19: 10为雄鸟炫耀高峰期；17:30-18：30和19: 10-19：30以觅食为主，中午一般躲在灌丛里避荫休息。伏巢雌鸟每天早晚各离巢1次 ...
