Lennuse (Lennus)
Patagium. Yes, right... Lennus also means ‘in flight’ and, historically perhaps, absent or AWOL, so that’s not much help. What bothers me is that it seems as if they just bunged any ole thang that looks bird-like into the Lilleküla bird-name group and hoped for the best. See also Sule and Tiiva, they’re a bit iffy too. A patagium is the skin used as gliding-mechanism by bats, flying-squirrels and whatnot (maybe umbrellas too?). But, yes, let’s call it a bird. In the meantime, they don’t have a single street in Tallinn with the proper name of Estonia’s national bird, suitsupääsuke, the barn swallow, Hirundo rustica (see Pääsukese or Suitsupääsuse instead).
