七星河自然保护区红嘴鸥孵化期行为研究

摘要

Black-headed gulls' behavioral regularity are observed and studied in QixingheNatural Reserve from May 10 to May 20 in 2014 while they were in the incubating period. Reproductive behaviors' time distribution as follow: feeding 36.14%, walking 22.51%, preening 15.65%, resting15.24%, alerting13.04%, fight-ing4.92%, courtship 2.23%, and less other behaviors. Two peaks period had appeared on day regularity which respectively is 6:00~7:00 and 15:00~16:00, ebb period appeared from 12:00 to 13:00. Walking behavior's peak period appeared in 7:00~8:00 and 14:00~15:00; edd period appeared in 12:00~13:00. Resting peak ap-peared in 12:00~13:00 and 17:00~18:00. Resting was stable on other times. Preening, alerting and fighting were appeared fre-quently stable. And courtships haven't found eminently regularity.%2014年5月10日~2014年5月20日在七星河保护区对红嘴鸥孵化期的行为规律进行了观察和研究，发现在孵化期的时间分配中觅食行占26.14%，游走行为22.51%，理羽行为15.65%，静栖行为15.24%，警戒行为13.04%，争斗行为4.92%，求偶行为2.23%，其余行为较少；日节律显示，觅食行为在一天中出现两次的高峰，分别是在6：00~7：00和15：00~16：00，低谷出现在12：00~13：00这个时间段，游走行为的高峰出现在7：00~8：00和14：00~15：00，低谷出现在12：00~13：00，静栖行为的高峰出现在12：00~13：00和17：00~18：00，在其他时间静栖行为比较稳定，无太大变化。理羽行为、警戒行为和争斗行为出现的频次较稳定，无大的波动，而求偶行为属偶见，未发现有明显的规律性。
