Names in English dialects are numerous. Scottish and north English dialects have included "ka" or "kae" since the 14th century. The Midlands form of this word was "co" or "coo". "Caddow" is potentially a compound of "ka" and "dow", a variant of "daw". Other dialectal or obsolete names include "caddesse", "cawdaw", "caddy", "chauk", "college-bird", "jackerdaw", "jacko", "ka-wattie", "chimney-sweep bird" (from their nesting propensities), and "sea-crow" (from the frequency with which they are found on coasts). It was also frequently known quasi-nominally as "Jack".
