This has been a pretty big issue in Ontario papers this year. Basically the gist of it is that Coyotes have been spotted more frequently than ever before. There was an article in the paper a few months ago that listed the amount of money farmers have been paid so far this year in compensation for Coyote kills. Said amount has tripled in the last five years. See below for that info.
We are seeing an increase of Coyote numbers where I live too. Just on Friday I drove by a rural elementary school. Beside the school they are doing construction and putting in a new subdivision. I don't know where all the workers were (it was lunch time so probably they went to town for a bite), but not one of them was about. There was however, a large Coyote hanging around in the construction site near the treed area between the elementary school and the backhoe. Lovely, eh? Never used to see them during the day but they are everywhere around here now.
I have lived on a farm in rural Ontario for many years. Before this year I have never been concerned with going out after dark; in fact I never thought twice about it. We have outdoor barn lights that are on solar energy and run all night long as well as night time radios, interior lights on timers, etc. running in the barn to keep predators at bay. Historically, the Coyotes generally stay away from our place and turn away to run if they see people. Unfortunately, our precautions are not working as well and these predators have come within a few meters of me and my dogs at night. We often spot them farther out during the day time and they usually stay pretty far then. I expect that soon enough they will come closer. Let them get hungry enough and they will come.
By the way ... in case you were wondering ... It's an extremely uncomfortable feeling to be hunted and I don't wish it upon anyone. You can tell they are thinking about it with the way they stalk around.
At this point, every time I walk outside with the dogs after dark I have something with me to fend off the Coyotes - baseball bat, big stick, flash lights. So far I haven't needed them *knock on wood* but that doesn't mean that I haven't started target practice with the .22. I don't want to shoot anything but if it comes to a choice between me and my dogs or a pack of Coyotes ... well, I'm sure you can bet which I will pick. I wonder how long it will be before I have to start taking it along with me during the day time as well?
Around here, there have always been instances where the Coyotes call out to the local farm dogs. When the dog goes out to investigate, the pack moves in for the kill. At this rate of increased sightings I can expect in the near future that we will be increasing our numbers of guardian animals. Even though we have never lost a dog to a Coyote attack, I certainly won't be letting my guys outside without supervision.
Day or night.
I don't recommend you let your guys out alone either; regardless whether you are in rural or urban areas. The Coyotes don't care if you are in a "safe" subdivision or on a farm. They are everywhere; hopping fences and grabbing pets/livestock. Keep your pets safe and make these important decisions for them. They are your responsibility and depend on you.
