How can a tiny swallow build an entire nest on a steep cliff using around 1,000 small balls of mud? 🐦 Watch how this incredible bird collects wet mud, carefully attaches each piece with its beak, and gradually builds a strong nest without support underneath. The nest takes shape layer by layer, forming a curved shell with a small entrance and a cozy interior lined with dry grass. Nature never stops surprising us! Discover the amazing nest-building skills of swallows and the incredible engineering hidden in the animal world.
