>> But I would rather go back and read my copy of Blaney since he looked carefully at hundreds of specimens from throughout the range of the taxon.
If you check your copy of Blaney, he clearly states in his conclusions of nigrita "unless additional collecting in Southern Sonora reveals specimens with L.g.splendida pattern, the differentiation of the population is sufficient to warrant it's recognition."
Yet, in his earlier discussion he sites an adult specimen caught 25.6 miles s Los Mochis, Sinaloa with typical splendida pattern. He attributes this specimen and another with a more reduced pattern to intergradation, even though this is near the southern portion of nigritas range, and the closest known population of typical splendida is seperated by the Sierra Madre Occidental. So, these specimens TO ME clearly fill his "specimens in Southern Sonora" that he himself says would invalidate nigrita.
