1.烟灰缸巢

These remarkable nesting locations show how birds can adapt to their environment. Although not all birds nest, they all build or look to find a safe place to lay and hatch their eggs. Until recently it was believed that nest building was an inherent skill, but recent studies suggest that birds can learn to improve.
这些不同寻常的鸟巢的位置展示了鸟类是如何适应他们的生存环境的。尽管不是所有的鸟都筑巢，但是所有的鸟都会建造或者找到一个安全的地方去栖息和孵卵。过去人们相信筑巢是本能，但是最近的研究表明，鸟类能够通过学习来提高这项本能。

Man-made birdhouses have existed at least since the 15th-16th century. As agriculture and urbanization altered the environment through deforestation, the number of natural nesting cavities decreased. Birdhouses, or creating nesting spots like those shown here, are a solution and response to this problem.
人造鸟屋至少在15-16世纪就存在了。农业生产、砍伐森林和城市化改变了环境，天然鸟巢也在减少。下面这些人造鸟屋或鸟巢是解决这个问题的方法。
