Tuesday, May 1: Bird songs are a primary signal of spring’s arrival—so what better way to celebrate than to stop by Bird Fest 2007 at the National Zoo (3001 Connecticut Ave., NW; 202-633-4800)?

Thursday, May 3: If you’re a serious beer lover, you might be interested in “The Art of Refermentation,” hosted by National Geographic Live. Garrett Oliver, brewmaster of the Brooklyn Brewery—one of America’s first microbreweries—will discuss refermentation, the rapidly fading art of fermenting beer in the bottle, cask, or keg rather than in a large fermenter. There will, of course, be beers for the tasting. Tickets are $65 (buy them here). At the National Geographic Society’s Grosvenor Auditorium (1600 M St., NW; 202-857-7700).
