Overlap of species distribution models of two species of army ants (columns; Eciton burchellii, carmine color, and Labidus praedator, caramel color) and five species of obligate ant-following birds (rows, amethyst color). Range overlap between army ants and ant-following birds is shown in lime color, and the percentage of overlap is represented numerically for each ant-bird species pair.
