Barn Swallow Nest

Did you know that all the swallow and martin species that occur in Portugal have different nesting habits? And that it's possible to identify which species of swallow a particular nest corresponds to?

In the case of the Barn Swallow (Hirundo rustica), the nests are small open bowls built with mud and straw and can be found in roofs, outbuildings or house façades, usually on urban peripheries or in rural areas. Although Barn Swallows nest solitarily, in occasional cases they can form small colonies.

If you come across one of these nests, or any other swallow or martin, record it on the website and help us conserve these birds!
