As drought continues, there is a tighter competition for survival since food becomes scarce. Creatures will adjust based on how they acquire food. Seed is the determining factor for the evolution of the birds’ beaks. Larger G. fortis compete with G. magnirostris for large seeds. But due to continuing droughts, food will become increasingly scarce resulting in the death of many G. magnirostris and G. fortis with large beaks, including the big bird lineage. And also, beaks of G. fortis will further reduce in size to be able to consume any available food sources.
