Targets, placed under the roosting places, accumulate droppings. Windows are frosted with glass wax so that the birds will not fly into them. The pigeons, making immediate use of the materials provided, construct their nests in the soft canvas pouches attached to corner spaces. Visitors to the gallery can walk comfortably through the space, which is large enough to allow pigeons and people to coexist.
Late in July 1990, a pigeon, walking on the keyboard of a computer (Apple Macintosh) located in an office within the space tapped out this message: "]]x xxxxx mp ``````"
The gallery is given over to two brown and white pigeons. The pigeons are provided with nesting materials, food, and a bicycle wheel as a potential roosting spot; they more often roost instead on the ceiling fans.
