Sociable weaver nests are the largest built by any bird and often look like massive haystacks in trees. The birds construct permanent nests that house more than 100 pairs of weavers. These nests were photographed in Etosha National Park in Namibia.

Cup nests are built by several small bird species, including hummingbirds and many passerines. Most of these nests are made from pliable materials like grasses, and many birds use spider silk in their construction.

Spider silk is lightweight, flexible and sticky, which can help bind to the nest to the branch or other item to which it’s attached. Here, a black-chinned hummingbird has built her nest upon an electrical conduit.

The Harris hawk often builds nests on cacti, and it’s the largest bird that makes a home on a saguaro cactus. Nests are constructed from sticks, roots and leaves and placed about 50 feet off the ground. The hawk is able to nest on the cactus by standing on the back of its talons to avoid needles.
