Not the high culture of art, literature and music, but an older process of transmitting traits and skills through generations.

These behaviours, though, can also change in response to pressures of natural selection, a term coined by Charles Darwin in his theory of evolution.

Studies at the Zoological Society of London have discovered that invasive species will compete with native birds for suitable trees to build their nests in.
伦敦动物学会的研究发现，入侵物种会与本地鸟类竞争适合筑巢的树木。
Experiments published in Science Direct also show that most female birds look for fresh, green nests when choosing their mate.
发表在Science Direct上的实验也表明，大多数雌鸟在选择配偶时会寻找新鲜、绿色的巢穴。
A report from RSPB further adds that in some species of birds, such as wrens, the male will build multiple nests from which the female can choose her favourite and even tidy it up.
皇家鸟类保护协会的一份报告进一步补充说，在一些鸟类物种中，如鹪鹩，雄性会建造多个巢穴，雌性可以选择她最喜欢的，甚至整理它。
This tells us that, like humans, the quality of a home, in addition to its location and cleanliness, can influence whether a pair of birds decide to live and start a family there.
这告诉我们，像人类一样，家园的质量，除了位置和清洁度外，还会影响一对鸟类是否决定在那里生活和组建家庭。
