for example, g. magnirostris eat large seeds, and g. magnirostris can outcompete all other finches. the big birds and g. fortis fight over smaller seeds and water holes, but the big birds are dominant to g. fortis because they are almost twice the size of g. fortis. given what you know about g. fortis, g. magnirostris, and the big bird lineage, what do you predict will happen as the drought continues?
