There are two episodes of Frasier where Frasier is involved with the condo committee, however I don't think he ever actually managed to get on the condo committee itself. The first is in Season 4, episode 11: Three Days Of The Condo. In that episode Frasier runs against the president of the condo board after she refuses his request to have an antique door knocker. The other is in Season 10, episode 3: Proxy Prexy. In this episode Frasier gets Martin to run for condo board president but using Frasier's ideas.
The episode is Season 11, episode 12: Frasier-Lite. He didn't actually eat the pigeon, he just had the pigeon in his mouth.
The episode is called "Mixed Doubles" and it's Episode 6 from Season 4 for "Frasier."
