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.
這些不同尋常的鳥巢的位置展示了鳥類是如何適應他們的生存環(huán)境的。盡管不是所有的鳥都筑巢，但是所有的鳥都會建造或者找到一個安全的地方去棲息和孵卵。過去人們相信筑巢是本能，但是最近的研究表明，鳥類能夠通過學習來提高這項本能。

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.
人造鳥屋至少在15-16世紀就存在了。農業(yè)生產、砍伐森林和城市化改變了環(huán)境，天然鳥巢也在減少。下面這些人造鳥屋或鳥巢是解決這個問題的方法。
