Featuring live flowering plants, Jeff Koons’ huge mirror-polished stainless steel bluebird not only represents nature but brings it into the gallery. It’s part of David Zwirner Gallery’s 25-year anniversary exhibition, which includes work by many of the world’s best-known western contemporary artists and makes clear the scale of the gallery’s art world involvement. (On view at 537 West 20th Street and all Zwirner locations in Chelsea through Feb 17th.)
