Why is the bird ont the right more likely to pass on its genes than the bird on the left?

The bird on the right may be more likely to pass on its genes if it possesses traits that make it more attractive to potential mates, such as brighter colors or more elaborate plumage. These traits can signal genetic fitness and attract more mating opportunities. Additionally, if the bird on the right exhibits behaviors that increase its chances of successful reproduction, such as effective courtship displays or superior foraging skills, it may also have a higher likelihood of passing on its genes to the next generation.
