What are some of the biggest animal migrations, the ones that would make the most impressive sight if you were there to see them?

The top few that come to my mind at the moment are monarch butterflies (North America), wildebeest (Africa), and flamingos (several species on different routes, but the biggest gathering seems to be at Lake Natron in Africa). But I have just a vague general sense that I've heard of others that aren't coming to mind right now...
