The genetic variations in bird beak shapes and sizes you are referring to likely arose due to the process of evolution by natural selection. These variations can initially appear due to random mutations in the genes that influence beak development. Once these variations are present in a population, natural selection can act upon them based on environmental pressures or changes in available food sources.
For example, birds with beaks that are better adapted for accessing specific types of food (like seeds, insects, or nectar) are more likely to survive and reproduce. Over time, this leads to a greater prevalence of those advantageous traits in the population, as those individuals with the more suitable beak shapes and sizes are more likely to thrive and pass on their genes to the next generation. This process ultimately contributes to the diversification of beak shapes and sizes in the bird population.
