We aren't experts, and we certainly aren't knowledgeable about every facet of evolutionary theory and paleontology. Why don't you write the actual scientists who found the fossil to get the specifics?
You have already been given an explanation for how Titaalik was predicted and then found, based on the predictions. Why do we need to
also know and tell you about some particular transitional bird?
On general principles, an area is chosen to look for specific fossils when it is known to be of the right age and when previous expeditions have determined the type of environment the sediments were laid down by. If they look for bird-dino fossils in a particular area, it is because it is of the right chronological age and/or because the environment is likely to contain fossils of that type.
Many organisms are specifically adapted to specific environments, so if you want to find fossils of them, you go to fossil deposits from such enviroments.
Take a guess about what kind of rock you'd look for a transitional whale. Hmm, maybe marine sediments for starters? This really isn't that mysterious Jerome, but you have to allow yourself a little thought first.
