绿鹭会把羽毛（甚至从公园捡到到鱼饲料）放在水面上守株待兔等小鱼上钩。雪鹭会用喙轻点水面模仿昆虫挣扎来钓鱼。

Green Herons have been observed placing small feathers ( and even fish food pellets found in a public park) on the surface of the water and then watching for small fish that come to the bait. Snowy Egrets often dabble the tip of their bill in the water to mimic a disturbance such as an insect struggling on the surface then catch any fish that come near.

（以人类的标准来说，鸟平时的站姿其实是”蹲着“的。所以鸟的”膝盖“才向后弯 —— 因为那根本不是膝盖而是”脚后跟“）

猎鹰（Falcon）捕猎的方式是从空中在飞行中的鸭子上方用超过 200 miles 每小时的速度飞踹鸭子，一般情况下鸭子会立刻被撞死或者击晕。

The ducks is hit from above as it flies, and often doesn't see the falcon coming. The falcon hits its prey with its feet, and the impact of being struck by a two-pound falcon traveling at over 200 miles per hour stuns or kills the duck instantly.

褐头牛鹂会“蹭”别的鸟巢，靠宿主来孵化和喂养自己的雏鸟。她在每个适合的鸟巢下一个蛋，一个季度可以下数十个。下完蛋后雌鸟并不会离开，而是会在附近监测蛋和雏鸟的情况。如果宿主把牛鹂蛋移除，雌鸟通常会报复性地摧毁宿主整窝的蛋。牛鹂雏鸟有天生分辨雌鸟叫声的能力，不会印随宿主物种。
牛鹂的蛋破壳比其他物种快几天，雏鸟会把宿主的蛋推下鸟巢，或者因为早出生更强壮在跟“兄弟姐妹”抢食物的斗争中胜出。如果牛鹂雌鸟发现宿主已经开始孵蛋，她可能会偷走蛋逼迫宿主下一些新的蛋，以便自己把蛋提前混进去（好让雏鸟赶在宿主的蛋之前孵化）。

（记得小时候看过忘了是课本还是绘本讲杜鹃类似的行为，气得跳脚。看了这个图才发现原来雏鸟跟宿主外观差别这么大……这不算是混进去的“寄生虫”了，直接是黑社会收保护费嘛）

很多鸣禽自带同时唱两首歌自己和声的功能。

Birds produce sound with the syrinx, which differs from our larynx by being made of two parts and located deeper in the respiratory tract at the point where the two airways from the left and right lungs and airs sacs join to form the trachea. Two complex sets of tiny muscles control airflow through the two sides independently, allowing the birds to produce two different sounds at the same time. In many songbirds the two sides are slightly different. These species produce higher sounds with one side and lower sounds with the other.

（视频为我今天目击到的一场鸽子求偶失败现场，就来段鸽子的 fun fact 吧。）
很多鸟走路摇头晃脑，这是为了保持视觉稳定把脖子当云台了。
实验中把鸽子放在跑步机上再蒙上眼睛，它们走路就不会晃头了。
Many birds bob their heads back and forth as they walk, and they do it to help keep their vision fixed on their surroundings... In experiments where pigeons walk on a treadmill or are blindfolded (so that the view does not change), they do not bob their heads.

如果公鸡对着你的耳朵打鸣，音量可以像 60 米外的飞机引擎一样响。（两个都是危险动作请勿模仿！）
If a rooster crowed in your ear, the sound would be as loud as if you were standing two hundred feet from a jet engine. (Neither is recommended!).

为什么哀鸽起飞会发出一种特殊的振翅声？
普通轻松起飞时通常同伴不会有什么反应，但是惊慌逃走的高频振翅声会对同伴和其他鸟类起到警报作用。
振翅声在求偶时也有展示作用，所以这很可能是这种振翅声被进化出来的主要原因，警报作用则是意外的附带效果。
Why do the wings of Mourning Doves make a whistling sound on takeoff?... the sound of a normal relaxed take off caused no reaction, but the sound of a panicked takeoff (higher pitched and with quicker wing beats) caused doves and the other birds to flee in alarm... Wing sounds are also used in the dove's courtship displays, so it's possible that the sound evolved mainly for that purpose, with the alarm function being a nice extra benefit.

鸟类过人的平衡能力，比如很稳地站在小树枝上，以及应对错综复杂的飞行环境，依靠的是它们对身体姿势的精确感知。
除了内耳像人类一样有平衡感知器以外，鸟类还有另一个平衡感知器在骨盆位置，这使它们能独立地平衡头和下半身。如果树枝摇晃带动它们的身体摇晃，它们可以保持头部稳定来抵消所带来的的位移。它们快速转动脑袋观察和清理羽毛也不会影响它们身体的平衡能力。它们知道只有头在移动，而不是身体。
Much of what birds do depends on an incredibly precise sense of body position, such as balancing on a tiny twig, standing on one leg, and negotiating the intricacies of flying... Having a motion sensor in the pelvis, along with one in the head (in the inner ear, much like ours), means they can keep track of the movement of two body parts independently. If their body is moving up and down because their perch is swaying, they can compensate for that while keeping their head stationary. Or if they spin their head around in rapid scanning or preening, it doesn't affect their ability to balance; they know that only their head is moving, not their body.
