Second runner up: “The Eurasian wren (Troglodytes troglodytes), or simply ‘wren’, is a small brownish bird that is easily recognized by its stump tail, beautiful song and quite assertive territorial behavior. The male wren builds nests in bushes, tree trunks or any suitable hole, even in buildings. This male wren, adapted to busy campus life, decided to build a nest under the saddle of a parked bicycle. The wren initially started to line the nest with soft material (pictured), and this is usually an indication that a female has chosen the nest for breeding. Despite efforts to avoid disturbance by biology students and staff using the parking lot, the nest remained unoccupied and finally was blown out during a spring storm.” Attribution: Raf Aerts
