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.
