Aircraft X was performing pattern work in left closed traffic on Runway 9 when Aircraft Y called inbound from the northwest. Aircraft Y was instructed to; and read back; enter a midfield left downwind for Runway 9. Aircraft Z was inbound from the south; was sequenced and cleared to land on Runway 9 behind Aircraft A. On roll-out Aircraft A reported two coyotes crossing Runway 9. At this time Aircraft Y had entered a 2 mile left base as opposed to a midfield downwind thus conflicting with Aircraft X who was now on a 2 mile extended downwind. Aircraft X was then issued a sequence and landing clearance. Aircraft Y was issued traffic and a right 360 turn for spacing. At this point the coyotes were spotted having sat down in the middle of Runway 9 about 3;000 feet down. Aircraft Z was issued a go-around as he was touching down. Aircraft Y was asked if he had Aircraft X traffic insight to which he applied in the affirmative. Aircraft Y verified once more that he had Aircraft X in sight before he was issued a sequence and landing clearance behind Aircraft X. A short while later Aircraft X reported that Aircraft Y had overtaken them on final having passed 50 feet overhead. Aircraft X was issued a left 360 turn to final to follow Aircraft Y to the runway.Something that seems to be sorely lacking at this airport is the absence of any wildlife management. Coyotes on the runway is a very regular problem on the airfield and a great hazard to those pilots operating on the field. The airport has no perimeter fence and the airfield management/ maintenance seem to take no action to reduce this sort of occurrence. The coyotes unfortunately have become very accustomed to the air traffic and are nonplussed by passing aircraft.
Aurora Tower Controller reported that the airport has problems associated with wildlife that enter the runway; which caused an unsafe situation for 4 aircraft that were attempting to land.
