A Sparrow is a UCB NY Harold Team.
When A Sparrow was formed, all the new, shaken up teams were given starter names that were anagrams of Neil Casey. A Sparrow's was A New Licey. In an email thread two days after they were formed, Diana mentioned she "had always wanted to be on a team called "A Sparrow"'. That was about it. The name "The Improvocats" was thrown in for good measure, but ultimately, Diana's first suggestion was agreed upon very quickly and that was that.
