  The sequences of two viruses detected in feral pigeons (Columba livia) have been deposited in the public databases (Kofstad and Jonassen, 2011). The two viruses are described as pigeon picornavirus A (FR727145) and pigeon picornavirus B (FR727144). Both viruses are most closely related to the sapeloviruses and enteroviruses. They also contain in their 3' UTRs an RNA motif called stem-loop-2-like motif (s2m) whose function is unknown. In fact there are two tandemly-repeated copies, called (s2M)2. This motif is also found near the 3' ends of some picornaviruses [equine rhinitis B virus (ERBV) 1, ERBV-2, ERBV-3, turdivirus (TV) 2 and TV-3)], astroviruses, caliciviruses and coronaviruses.
