A species of bird had an original range covering the entire eastern half of the United States from New England down to Florida, west to the Rocky Mountains.
 
  During a period of glaciation, the eastern part of the range was cut off from the western part for 2000 years. Then the glaciers melted and the birds' original range was reestablished.

What evidence will they look for in their study?
