Pigeon Parking
The roof of the tower over the front door of the Walter J. Sullivan Water Purification Facility is a popular perching spot for pigeons. Ancestors of these non-native birds from Europe and Asia, also called Rock Pigeons, originally perched on rocky cliffs. Their modern descendents discovered the benefits of manmade structures for perching, and the ease of living on food scraps left by careless humans.
