According to the National Park Service:
“Are there coyotes in Rock Creek Park?
YES- The first recorded sighting in the park was in May 2004; they were confirmed by park staff in September 2004. Sightings have been recorded continuously since 2004. Most of the sightings have been in the upper section of the park between Military and Wise Roads. Several sightings have been reported in the neighborhoods adjacent to the park as well. Presently, there is no estimate of the population size in the park but the number is believed to be small.
Are they dangerous to people?
Coyotes generally are not interested in confronting people, even small children. Of course, parents should always keep an eye on children while in the park, but coyotes pose no special danger. They are usually not aggressive toward humans unless humans attempt to feed or interact with coyotes. While there are reports of coyotes attacking and killing a person, these types of incidents are extremely rare. Remember, coyotes are wild animals. They can be seen during the day, but they are most active in the evening and at night when the park is closed to pedestrian visitors.
Are they dangerous to pets?
MAYBE- Coyotes will hunt house cats and small dogs. However, if your pet is leashed (as DC and National Park Service regulations require) and you and your pet are on a trail (as Rock Creek Park regulations require), a coyote will likely not try to attack.
What should I do if I see a coyote?
You can stop and watch, but do not approach it. As with any wild animal, if it feels threatened by someone coming toward it or chasing it, it may feel the need to protect itself. DO NOT FEED or attempt to feed them. Once a wild animal gets accustomed to being fed by humans there is much more likelihood that an individual will get bitten by an animal looking for food.
