FIGURE 1. Map of Colombia, showing the geographic origin of specimens and tissue samples of Turdus thrushes analyzed in this study. A. Distribution of Turdus leucomelas in Colombia. T. l. upichiarum is restricted to the Serranía de Chiribiquete and Araracuara, whereas T. l. albiventer is found across the Orinoco basin and trans-Andes and T. l. cautor is limited to the humid tip of the Guajira Peninsula. The regions mentioned in this study are listed from north to south as follows: a. the Guajira Peninsula; b. the Santa Marta region; c. Serranía de Perijá; d. Eastern Andes; e. Magdalena River valley; f. Llanos Orientales; g. Serranía de la Macarena; h. Serranía de Chiribiquete (the star denotes the type locality of T. upichiarum); i. forested Amazonian lowlands. B. Distribution of four Turdus thrushes in eastern Colombia. Localities specifically mentioned are numbered north to south as follows; 1. Inírida; 2. Guayabero River; 3. Chiribiquete; d. Puerto Abejas and vicinity; g. Araracuara; h. Leticia. Nominate T. ignobilis occurs on the western slope of the Eastern Andes and usually at somewhat higher elevations than T. i. debilis, but we note several sites where possible intergrades between them exist. T. arthuri occurs rather widely in eastern Colombia, and is sympatric with T. i. debilis at Araracuara and Inírida, and with T. l. upichiarum in Chiribiquete and Araracuara.
