The arrival of migratory birds before them can be deprived of them from convenient places of food and lodging. And there is a food crisis in the late birds. With that, due to reaching the uneven, the life crisis will fall in their newborns. Even if there is no impact on the increase in temperature due to long-term birds, they also need to be different. They will also be deprived of the necessary benefits due to the birds already reaching their time. Takuji Ushi of Edinburgh University said that the growth of this warmth has been adversely affecting the biology of many plants and animals. Especially for those whose breeding and reproduction are dependent on the spring. He also said that this study has allowed the migratory birds to know what their behavior might be in the changing breeding grounds. This study found a worrying picture of changes in the behavior of birds that change the habit of changing seasons, food availability, and environmentally friendly reproduction. It is certain that global warming is affecting their life-cycle.
