Step-by-step explanation:
According to the problem, a species of bird disperses in the South in a random pattern. A random pattern is equivalent to a random dispersion. In random dispersion, individuals are distributed randomly, without a predictable pattern.
For example, consider the following pictures:
1. In the following image, we can observe a uniform distribution, where individuals of a population are spaced more or less evenly:
2. In the following picture, we can observe a clumped dispersion, where individuals are clustered in groups.
Note that none of the above images have a random pattern, but the type of scattering can be predicted in each one.
Then, we can conclude that the correct answer is:
