It's already being observed. Bird migrations have been happening earlier/later, and ranges of birds have increased. I'm sure the same thing is happening for whales / ocean animals.

According to this one[1], they're adapting by leaving later, and flying faster/taking less breaks to make up for the lost time. The result being that less of them make it to the breeding grounds (6% decrease in survival rate).
