Why birds use pet fur for nests

In the wild, birds will typically use whatever material is readily available to them in their environment to build their nests.

According to All About Birds from Cornell University, the nesting material is also used to "insulate roosting cavities," keeping nests warm in winter. Pet fur, specifically "pet fur taken from the undercoat" or "fine pet hair," may not be as useful for building a nest, as it's considered too fine, but the thicker coats are best, especially for protection against water.

Typically, the best material for nests is "made of vegetation and sometimes mud" for structural purposes.

"The outer layers are of coarse material, and the inside is lined with softer or finer material," the organization explained. They also note that other species may use other organic material, such as "spider silk," for flexibility and ensuring the nest is stable.
