Red-rumped Swallow Nest

Did you know that there is a species of swallow in Portugal whose nest is occupied by White-rumped Swift (𝘈𝘱𝘶𝘴 𝘤𝘢𝘧𝘧𝘦𝘳)?

Red-rumped Swallows (𝘊𝘦𝘤𝘳𝘰𝘱𝘪𝘴 𝘥𝘢𝘶𝘳𝘪𝘤𝘢) nests are closed mud bowls with a circular entrance and an access tunnel. And unlike other swallows that glue the mud bowl to the wall or eaves of a building, this species builds its nest on the roof.

These nests, sometimes used by swifts, are usually built in places that are difficult to access, such as bridges, viaducts or even underground canals. So the next time you cross a viaduct, look out for a swallow's nest and keep an eye out for its occupants.
