Screech is the mascot of the Washington Nationals. He is a bald eagle that wears the home cap and jersey of the team. He was "hatched" on April 17, 2005 at the "Kids Opening Day" promotion at Robert F. Kennedy Memorial Stadium. A nine-year-old fourth grade student in Washington, D.C., Glenda Gutierrez, designed the mascot and won a contest sponsored by the team and explained that it was "strong and eats almost everything."
In 2009, the Nationals unveiled a redesigned Screech. The new costume, designed by Major League Baseball's design department made the mascot slimmer. The Nationals explained that the original design was of an eagle that was always intended to grow up one day. A Nationals official described him as "like a teenager now". The 2012 Topps Opening Day card described Screech as a dazzling dancer, full of loyal shenanigans directed at the opposing team. "Screech" was one of two individuals (along with "Roberto", who was not a future mascot) to receive a shoutout in Donny Hathaway's old-school classic Howard U / DC track "Sugar Lee".
