From his first crop of foals to race, Birdstone sired Mine That Bird, who had several wins as a two-year-old gelding before winning the 2009 Kentucky Derby as a three-year-old. Another of Birdstone's top runners was Summer Bird, who upset Mine That Bird in the 2009 Belmont Stakes (later winning the Jockey Club Gold Cup). His first crop also included Birdrun, who set the Belmont track record at a mile and a sixteenth . Birdstone was one of the top ten ranked freshman sires of 2008 with 11 winners out of 22 starters and stood for $10,000 for the remainder of the 2009 season, despite his first-crop success.

Birdstone has sired 30 black-type runners, 19 stakes winners, 8 graded stakes winners, and has amassed progeny earnings over $21 million. Birdstone's most notable progeny includes:
