The animal ran off after attacking the resident. The victim reported that a second possible coyote was seen nearby. City employees searched the area, but could not find either animal.

Coyote attacks on humans are extremely rare.

Calls for coyote sightings have increased since Aurora and other cities began a public awareness campaign. Many of the animals are being squeezed out of their natural habitats by development and are forced to look for food in residential areas.

The city advises carrying a walking stick. Anyone spotting a coyote should call Animal Control at 630-256-3630. If the coyote is attacking a person, the resident should call 911 and Animal Control will also be contacted.
