| 1987～1995年对58只20～25日龄的环志朱鹮进行了生物学特性观察,其中捕回进行人工饲养3对,繁殖一代朱?13只;人为杀害2只,天敌致死2只,因病死亡6只,失踪13只,野外存活28只,繁殖一代朱鹮17只;朱鹮在自然配对时有近亲繁殖的回避性,最早繁殖年龄为2岁,配偶与营巢地点有相对稳定性;疾病、天敌和林区破坏是朱鹮濒临灭绝的主要因素。 |

| Abstract: |
| The biological characteristics of 58 crested ibis marked with color plastic
rings have been observed for 9 years. Of all the marked birds, 6 were captured and
raised, 2 were intentionally killed, another 2 were killed by natural enemy, still another
13 missed, and 28 survived in open fields.The birds raised and the ones in open fields respectively reproduced 13 and 17 birds.The birds mated naturally showed the avoidance
of inbreeding, and began to reproduce at the age of 2. In addition, the birdsmating relationship and the places to nest were relatively stable.Disease, natural enemy and forest
denudation were primarily attributed to the birds extinction. |
