Tree Swallow

This Tree Swallow nest box has many layers of grasses and thin twigs, and is lined with large feathers from other birds. The female lays eggs and incubates them by herself. The eggs hatch in about 14 days. The hatchlings typically fledge in 16--24 days. When there are young birds or eggs in the nest, adults frequently dive bomb intruders (including humans) and attempt to scare them away from the nest.
