Last season I saw a cow-bunting fully grown following a "chippie" sparrow about, clamoring for food, and really looking large enough to bite off and swallow the head of its parent, and apparently hungry enough to do it. The "chippie" was evidently trying to shake it off and let it shift for itself, for it avoided it and flew from point to point to escape it. Its life was probably made wretched by the greedy monster it had unwittingly reared. INDEX Accentor, golden-crowned. _See_ Thrush, golden-crowned.
