Beak variations refer to differences in size, shape, and function among bird species. These variations are often adaptations resulting from environmental factors and food sources.
As mentioned earlier, it is nature's way of favoring organisms better adapted to their environment so they can survive and reproduce more effectively than less well-adapted competitors.
