Patterns of migration rates across localities. Plots of migration rates using the PB2 phylogeny (as an exemplar) on a two-dimensional matrix where each cell represents a rate between two locations. Each cell is color-coded according to the migration rate between the locations. The matrix is symmetric and location labels on the x- and y-axis are ordered so that locations belonging to the same flyway are placed next to each other
