Here in Maryland, it is said there are coyotes in every county. There is not a lot of open space left (at least in my area), so wildlife encounters rise every year. The bear population has been increasing so there are more and more suburban sightings. Coyotes are very opportunistic, now that you have seen one you know to be more vigilant. So far I have not seen a coyote in my yard, but I have had a fox on my back deck looking in the back door. If you continue to see it, I would see about getting a trapper to come and get.
