Saw-wing

The saw-wings, Psalidoprocne, is a small genus of passerine birds in the swallow family. The common name of this group is derived from the rough outer edge of the outer primary feather on the wing, which is rough due to recurved barbs. The function of this is unknown.[1] The birds are 11–17 cm long and black or black-and-white in colour.[2] The genus has an African distribution and all species can be found foraging over forest and woodland.[2] The last part of their scientific name comes from the eldest daughter of King Pandion of Athens, Procne, who was turned into a swallow after tricking her abusive husband.

gollark: So can you explain this "locally confluent" thing?
gollark: I was going to check Wikipedia, but it seems to be broken and I don't have a copy saved any more.
gollark: Basically just descending the tree of ingredients for a recipe until it finds stuff it has, or something.
gollark: I had *an* approximation which was pretty computationally simple. It just wasn't very good.
gollark: Does it? I thought it could at least fall back to something you had materials for. Huh.
