An interesting side story to the mission appears in the March 3, 2010 NASAspaceflight.com article 'STS-131: Discovery rolls out to Pad 39A - ET repaired following bird vandalism.'
The story about birds and the space shuttle Discovery continues on page two.
Birds had accessed the external tank (ET) and pecked off some of the Thermal Protection System (TPS) foam. Engineers were forced to repair the ET caused by the birds.
