Birds of prey can swoop, but I seem to remember that the falconers call it a "stoop". I have a couple times seen peregrine falcons stoop on a pigeon, with an explosion of feathers awesome to behold. And I remember Oliver Goldsmith's "She Stoops to Conquer" but never knew in what sense the word was used in the title. I invite members to express opinions on that while I finish reading the play to find out.
