丹顶鹤繁殖期行为时间分配及活动规律

Time Budget and Activity Rhythm of Red-crowned Crane (Grus japonensis) During Breeding Season

在扎龙国家级自然保护区 ,对繁殖期的丹顶鹤进行了观测 ,结果表明 :丹顶鹤繁殖期的各种行为具有较强的规律性 ,所占频率依次为 :繁殖 38.34%、觅食 2 9.14 %、警戒 15 .6 7%、静栖 9.13%、游走 5 .77%、其它1.95 %。在不同繁殖阶段 ,丹顶鹤各种行为的时间分配存在一定差异。在产卵前期 ,觅食行为比值最高 ;在孵卵期 ,繁殖行为比值最高。

From April to May 2000, behavior rhythm and time budget of red-crowned crane were studied in Zalong National Natural Reserve. The results showed that: various behaviors of red-crowned crane during breeding season are regular. Breeding behavior consists of major activity during breeding period, accounting for 38.34% of the whole time budget, then feeding (29.14%), alert (15.67%), resting (9.13%), locomotion (5.77%) and other behaviors (1.95%). Time budget of various behaviors is significantly different during different breeding phases. Feeding behavior is the highest in the time budget of red-crowned crane in early egg lying period. Breeding behavior is the main behavior during incubating period. Temperature and climate are major factors that affect behavior of breeding season.
