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.
The Drought Continues
As the drought continues, all crops, minerals and nutrients will be lessened. If it continues then it will cause severe shortage of food for humans and animals which can cause even death. There is a strong contest for lack of food and water.
Food will become limited. Animals will coordinate how they get nutrients. Seed is the deciding constituent for the development of the birds’ beaks.
Larger G. Fortis will have clash with G. Magnirostris for the best available food that is the large seeds. Severe drought can cause death of many G. Magnirostris and G. Fortis that contain large beaks also comprise the big bird origins.
Consequently the result of this would be the beaking of G. Fortis that will ultimately become more small. In presentation it would be in size that they can avail food which is currently avaiable.
