Bird Town, a candidate for champion 3-year-old filly, has been retired from racing. A homebred for Marylou Whitney, the daughter of Cape Town finished second in the Oct. 4 Beldame Stakes (gr. I) at Belmont Park on the same card that her half-brother, Birdstone, thrust himself as a champion contender by winning the Champagne Stakes (gr. I) for 2-year-olds. Bird Town, who was produced from the Storm Bird mare Dear Birdie, won the Kentucky Oaks (gr. I) and Acorn Stakes (gr. I) in consecutive starts in the spring. Earlier in the winter, she won the Charon Stakes by 12 1/2 lengths.Bird Town retires with four wins and six seconds from a dozen starts and earnings of $871,251 for trainer Nick Zito. Her other career stakes-placings came in runner-up efforts in this year's Test (gr. I) and Stonerside Beaumont (gr. II) Stakes and a third in the 2002 Three Rings Stakes. Bird Town will take up residence at Graham J. Beck's Gainesway Farm near Lexington after a letdown of a couple weeks at Zito's New York barn, and a decision as to a mate will be announced later.
