We need an equation to work with.
there beaks change depending on what type of year it is if it a dry year there beaks are strong and big but wet year they are small and fragile
The 1977 drought on Daphne Major resulted in a scarcity of small soft seeds, the primary food source for medium ground finches. This forced the finches to adapt by developing larger beaks to better crack open harder seeds, leading to evolutionary change in the population. Finches with larger beaks were more successful at obtaining food and had a higher chance of survival, passing on this trait to future generations.
Variation
Ravens are black and larger than songbirds but not as big as falcons. Their beaks have a minor curve and are fairly large
there are hard bird beaks and soft donkey beaks specify which type you want they have razor sharp beaks.
Yes, to my knowledge all birds have beaks yes they do. if they did not have beaks then how would they
yes they do have beaks
Even though they have long mouths that look like "beaks", they are not considered "beaks".
With evolution the beaks transformed into long beaks for eating bugs and short beaks for eating seeds
