Nesting Habits of Birds Reading Comprehension Lesson

Why Birds Build Nests

Birds make their home in something called a nest. This is where a bird lives and takes care of its young. If a bird is going to lay eggs, it needs a place that is safe and warm. The nest keeps the eggs protected until the babies are ready to hatch. Once the eggs are laid, the mother bird will often sit on them to keep them warm. Baby birds break out of their shells by pecking at the inside until they can push their way out.

Think of a nest the way you would think of your own house. Your house keeps you safe, dry, and warm. Nests do the same thing for birds. Unlike houses, though, nests can be placed almost anywhere — in a tree, on a rooftop, along a rock wall, on the ground, or even hanging from a branch. Birds choose a location that gives them the best protection from rain, predators, and harsh weather.

Most birds build their nests using whatever materials they can find nearby. Common nest materials include twigs, grass, leaves, mud, moss, and feathers. Some birds weave these materials tightly together to create a sturdy cup-shaped nest. Others gather softer materials to line the inside and make a comfortable place for their eggs. The size and shape of a nest depends on the species of bird that builds it.

Types of Bird Nests

Different birds build very different types of nests. Barn swallows use mud and grass to build cup-shaped nests that they attach to the sides of buildings, bridges, or cliffs. City birds like sparrows and pigeons often nest on building ledges, in gutters, or in other small sheltered spaces where they are protected from wind and rain. Eagles build enormous platform nests called eyries high in tall trees or on rocky cliffs.

Woodpeckers are unique because they carve their nests directly into tree trunks rather than building on the outside of a branch. Using their strong beaks, they chip away at the wood to create a hollow chamber inside the tree. This type of nest is especially safe for baby birds because it is enclosed on all sides and difficult for predators to reach.

Some birds in tropical areas build hanging nests that dangle from tree branches. These nests look like woven baskets with an entrance hole at the side or bottom. The swinging motion of the hanging nest makes it very hard for predators to climb in. Some of these clever birds even build a false entrance that leads to a dead end, fooling predators and protecting the eggs inside.
