Ecological succession , or the process in which the structure of a community evolves over time, means that the species composition, density, and distribution of that community is constantly changing as time progresses. A community may eventually reach its climax, the point where the composition remains mostly stable unless some sort of disturbance occurs. Otherwise, communities are constantly changing.

Study of the analogy i.e., the convergent evolution of the birds would help in that case. If we study the analogy of the birds, we would be able to know about the environment that they live in. For example, if the birds have the granivorous features, then it is confirmed that lived in or near a forested environment. The birds or animals, in general, adapt themselves to live in a particular condition or climate, without which they would die. Therefore, typical features of the birds provide information about their habitat.
When modern and fossil birds have similar features, that means that both birds lived in a similar type of climatic conditions and thus, did not had to change or adapt themselves differently.
