I just returned from the Big 12 Baseball Championship in Oklahoma City, Oklahoma and the NCAA Baseball Regional in Houston, Texas. I counted as many pigeons at the games as sports fans. I learned the birds are common in most large cities. Apparently, they are quite common at AT&T Bricktown Ballpark in Oklahoma City and Reckling Ballpark in Houston. They feed on the leftover sunflower seeds in the stands and near the dugouts. They also swoop down during the game to ingest the gravel on the infield base paths. The grit helps their digestion. Ironically, the names of the two teams that regularly play at both ballparks are the Redhawks and the Owls, both natural predators of the pigeon.
