英国St Andrews大学的科学家发现，鸟儿能学会挑选最佳的筑巢材料。而此前科学家认为筑巢材料的选择是由鸟儿的基因决定的——每一种鸟都有一种先天的筑巢模板。科学家设计了一个实验，测试鸟儿是否能根据材料的属性选择筑巢材料。他们给一群斑马雀较为柔韧的线，给另一群斑马雀较更硬更有利于筑巢的线。随后他们让两组鸟在两种线之间进行选择。第一组鸟立即选择了坚硬的筑巢材料。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
