Races form three groups, “rufivirgatus group” (rufivirgatus, ridgwayi and crassirostris), brighter-plumaged “Yucatán group” (verticalis and rhyptothorax), and even brighter and shorter-tailed “Pacific group” (superciliosus, sinaloae, sumichrasti and chiapensis); these sometimes considered to represent three separate species, but morphological differences are relatively slight and “their songs and calls are all similar”#R; own analysis indicates “Yucatán group” to be moderately distinct#R. Race ridgwayi weakly differentiated, and possibly an intergrade between nominate and crassirostris; verticalis intergrades with crassirostris in Campeche and with rhyptothorax in C Yucatán. Nine subspecies recognized.
