【自然科学-生物】 Pinkest flamingos fight the hardest for food, scientists learn
文章大意
研究表明,羽毛越鲜艳的火烈鸟在争夺食物的过程中越具有攻击性,羽毛鲜艳程度也是它们是否 健康的一个指标。人类应该为人工饲育的鸟提供尽可能宽阔的进食空间,来模拟野外觅食的环 境,让火烈鸟更加健康幸福。
总结分论点
第 1 段:粉红色的火烈鸟最具攻击性 第 2-4 段:颜色是一项重要的指标,越是粉色的羽毛代表火烈鸟越健康 第 5-10 段:科学家通过实验发现圈养的鸟类应该尽可能在广阔的空间喂养,以减少攻击性。 第 11-12 段:该小组还发现火烈鸟的颜色会产生变化,据此提出了改善鸟类福利的建议 第 13 段:之前的研究还发现火烈鸟会和朋友待在一起
句子摘抄:
A healthy flamingo that is an efficient feeder – demonstrated by its colourful feathers – will have more time and energy to be aggressive and dominant when feeding.
It’s not always possible to feed these birds outdoors, as lesser flamingos only weigh about 2kg and are native to Africa, so captive birds in places like the UK would get too cold if they went outside in the winter.
The colour comes from carotenoids in their food, which for lesser flamingos is mostly algae that they filter from the water.
No difference was found between males and females in rates of feeding or aggression, the researchers said
