This is an article about a single fossil parrot bone found in Siberia. They only found the sum total of ONE bone but even finding one is kind of like a miracle because birds bones, been so light and hollow, don't stand the test of time so fossils are very hard to come by. But the super interesting thing about it and where they found it is that the old theory that parrots from Africa flew across the Atlantic to reach the Americas is now in doubt and they think that they might have used the land bridge. This actually makes more sense than the flying across the ocean because parrots are not long distance fliers...
