Loggerhead Kingbird (Tyrannus caudifasciatus taylori) 27 January 2012. Bosque Estatal de Maricao, Maricao Municipality, Puerto Rico
This was one of a pair constructing a nest in a nearby utility pole. This photo seems to show a square tail with narrow rusty fringes. These are supposed to be characters indicative of the Hispaniolan race (T. c. gabbii). Perhaps the two races overlap in these characters more than thought. Both races are decidedly browner than those elsewhere in the Caribbean and both lack the white tip to the tail of those other races.
While a three-way split has been proposed by Garrido et al. (Wilson J.Ornith. 121:703-713, 2009) and a follow up article by Wiley et al. (J. Carib. Ornithol. 23:19-30, 2010) it appears this complex is in need of detailed genetic and vocal studies which would help clarify the taxonomic situation. Unfortunately, the above two papers do not include any genetic work.
