Yellow-breasted Chat

The Yellow-breasted Chat is the largest warbler-like bird in North America and so behaviorally unusual — with its loud, rambling song of whistles, chortles, and clucks — that it was recently moved out of the wood-warbler family into its own monotypic family. Males often sing at night and perform odd flight displays with dangling legs. Despite its bold yellow breast and white spectacles, it is frustratingly secretive in dense thickets.
