| 2012年5~7月,应用e-Science信息技术和标记法,对陕西神木县红碱淖(N 38°13'~39°27', E 109°42'~110°54')遗鸥(Larus relictus)的育雏行为和雏鸟生长发育进行了研究。结果表明,雏鸟由双亲共同承担喂食。育雏前期,亲鸟采取直接喂食、食物呕吐于巢边和在巢中间断性喂食这3种喂食模式;亲鸟昼间平均喂食(0.706±0.036)次/h,夜间平均喂食(0.469±0.024)次/h,双亲在喂食频次上无显著差异(F=32.54, P >0.05)。育雏后期,主要采取双亲直接喂食和亲鸟把食物呕吐于地面上,由雏鸟自己取食的喂食模式;亲鸟昼间平均喂食(0.416±0.021)次/h,夜间平均喂食(0.331±0.018)次/h,亲鸟喂食次数与雏鸟的日龄存在相关性(r=0.074, P<0.05)。随着雏鸟日龄的增长,暖雏次数趋于减少,而在炎热晴天、降雨和大风等天气状况下,暖雏时间和护雏行为都增强。雏鸟20日龄后未再观察到暖雏行为。雏鸟体长及外部器官的形态学参数适合用Gompertz曲线方程拟合。同时,与其近缘种黑嘴鸥(L.saundersi)的育雏行为和雏鸟生长进行了比较。 |
| 英文摘要: |
| The brooding behavior and nestling growth of Relict Gull (Larus relictus) were observed using e-Science information technology and marked method in Hongjiannao(N 38°13'-39°27', E 109°42'-110°54'), Shannxi Province from May to July 2012. Nestlings were feeding by parent. Three feeding patterns were recorded in pre-brooding periods. Parent fed nestling in average 0.706±0.036 times/h in daytime and 0.469±0.024 times/h in night, respectively, the feeding frequency by male and female was no difference (F=32.54, P>0.05). In the post-brooding period, parent showed two feeding modes, the feed frequency was average 0.416±0.021 times/h in daytime and 0.331±0.018 times/h in night, respectively. Feeding frequency was related to age of nestlings (r=0.074, P<0.05). The frequency of warming nestlings tended to decrease as the chicks grew older. While, parent spent more time on warming and safeguarding chicks was increase largely in the day with bed weather. No any brooding behavior was recorded after the chicks reached to 20 day old. The growth curves of body weight and body length were suitable to fit to Gompertz curves. |
