The Barn Swallow is one of two types of swallows I have seen, if I haven't forgotten any. According to the 'All About Birds' website, "the barn swallow is the most abundant and widely distributed swallow species in the world." It is distinguished by its cobalt blue and orange-brown colors. It normally has a white chest and white spots on its wings. Another distinguishing feature is its long forked tail. For some reason this one seems to have some orange on its chest.

But watch out for the single male! "An unmated male Barn Swallow may kill the nestlings of a nesting pair. His actions often succeed in breaking up the pair and afford him the opportunity to mate with the female." - https://www.allaboutbirds.org/guide/Barn_Swallow/overview
