摘要
黑龙江七星河国家级自然保护区位于三江平原腹地,是丹项鹤的重要繁殖地,2011年4～5月对保护区繁殖前期的丹顶鹤孵化行为进行了观察,结果表明:丹顶鹤孵化期的各种行为具有较强的规律性,各行为频率依次为:繁殖31.34%、觅食28.26%、警戒20.12%、静栖8.99%、游走4.51%、其他6.78%。在不同繁殖阶段,丹顶鹤各行为的生境分配存在一定差异。在产卵前期,繁殖行为主要发生在芦苇火烧地,觅食行为主要发生在农田;在孵化初期,繁殖行主要发生在苇丛里,觅食行为主要发生在芦苇火烧地。
Qixinghe National Nature Reserve of Heilongjiang province is located in the center of the Sanjiang Plain and is an important breeding site for Red - crowned Crane.From early April to late May 2011,we observed the pre - hatching behaviors of adult cranes during the early breeding period.Various breeding season behaviors of adult Red - crowned Crane are regular. Pre -hatching behavior consists of major activity during the breeding period,accounting for 31.34%of the time budget,followed by foraging（28.26%）,alert（20.12%）,resting（8.99%）,locomotion（4.51%） and other behaviors （6.78%）.Habitat distribution of various behaviors is significantly different during different breeding phases.Early in nesting, breeding behavior occurs mainly in burned reeds,foraging behavior occurs mainly in farm fields.Early in brooding, breeding occurs mainly in reed clumps,and foraging behavior occurs mainly in burned reeds.
