FIGURE 4 in A new genus and species of tanager (Passeriformes, Thraupidae) from the lower Yungas of western Bolivia and southern Peru
FIGURE 4. Confirmed localities of Heliothraupis oneilli plotted as black dots and predicted distribution based on our modeling, using parameters set at 50% suitability, with the predicted breeding range (in gold) and predicted nonbreeding range (in purple) plotted on a false color map of elevation of the eastern slope of the Andes in western Bolivia and Southern Perú. From the confirmed observations reported, we believe that this species breeds inhigh densities ina small region (~2,500 km2), and then disperses toa much larger zone (~26,000 km2) in the nonbreeding season, resulting in considerablylower population density at thattime.
