红腹锦鸡的越冬生态观察

保护区境内的红腹锦鸡栖息于海拔１０８０米－１８００米的落叶阔叶林和针阔混交林,冬季集群活动于巴山木竹林,农田,荒地,各群的大小和当年的繁殖成活率有关,集群时间和气温,降雪有关,繁殖成活率高,群内个体数量多;气温低,降雪早,集群开始早,三官庙,大古坪１６个群,各群的个体数,性比,在观察期逐年变化,日活动以觅食为主,占全天活动时间４０％以上,并在７：３０－１０：００、１６：００－１７：３０分别形成取食     

青岛地区暗绿绣眼鸟繁殖生态研究

暗绿绣眼鸟每年４月２０日迁来,５月中下旬筑巢,筑巢期７天。筑巢期间交配,巢成后即产卵。每窝产卵４枚,年产１窝。孵卵期１０天。雏鸟均在孵卵期的最后一上小时内全部出壳。经亲鸟喂食１１天,雏鸟出飞离巢。     

河乌繁殖生态的研究

河乌为栖息于水域的鸟类中生活习性较特殊的种类,以水中的昆虫和河流附近的害虫为食,在新疆分布于天山南北。3月左右开始婚配,夏、秋两季一般可以繁殖1—2次。每窝产4—5枚卵,孵化期为16—18天,雏鸟需要25—28天育成。河乌通常成对活动,贴水面飞行,生活在湍流溪河的两岸。冬季聚成小群常以2—7只在河道的冰洞及不冻水域活动、觅食。     

红腹锦鸡鸣声声谱分析

本文对笼养红腹锦鸡的啼叫,求偶,炫耀,恐惧,惊叫等鸣叫声进行了声谱分析,探索不同呜声特征与行为的关系,并将该雄体繁殖期的主要鸣声－蹄叫声与白腹锦鸡进行了比较。     

光周期诱导红腹锦鸡冬季繁殖效果初报

?College of Life Science, Hebei Normal University, Shijiazhuang 050016, China)Golden pheasant ( Chrysolophus pictus) is a monotypic and special species of China.In nature, it breeds once a year in spring summer.From Oct.1998 to Feb.1999, we studied the effects of photo periods on inducing the birds to reproduce in winter and succeeded.In the experiment, 36 adult females and 18 males were divided into three groups.Each group was divided into 6 replicates, each replicate included 2 females and 1 male, and fed in one cage.All the groups were exposed to short day (8L∶16D) for 8 weeks, and then transferred to long day (12L∶12D, 14L∶10D or 16L∶8D). In result, photoperiods significantly affected Golden pheasant reproductive performance in winter.Considered of all of the reproductive performance indicators, the reproductive performance of the group exposure to 14L∶10D was the best, the 16L∶8D group's was less and the 12L∶12D group's was the worst.It may be that the birds' CDL (critical day length) for inducing egg production was about 12 h, and the CDL for optimal egg production was 14L∶10D in winter. The birds exposed to 12L∶12D had no fertilized egg.The other groups had fertilized eggs and the fertility was 15 05% (14L∶10D) and 20 41% (16L∶8D).The hatchability of fertilized egg were 76 47% (14L∶10D) and 80 00% (16L∶8D). The egg laying pattern was affected by the size of photoperiod.The ratio of lay of the birds exposed to 14L∶10D, increased rapidly and sustained in a peak level for 5 weeks, and then fall down.But the other birds (group A and C) increased to the peak at the first week and then fall down quickly.     

红腹锦鸡的饲养繁殖与雏鸟生长发育

对红腹锦鸡的饲养繁殖与生长发育进行了研究和讨论。4～5月为产卵期,驯化当年能产少量卵,第2年每窝卵12～13枚,产卵期21～28d。家鸡代孵孵化期为21d,雌鸟自然孵化23d。最佳孵化方式为电孵卵器孵化,其次为雌鸟自然孵化。记述并统计分析了孵化过程中卵重、气室的变化以及体重及尾羽生长情况。体重及尾羽生长呈“S”形生长,前后期较慢,中期生长较快。
