1. Fall and Winter, When spring & summer come around you will have crops and tall grasses that will hide the Coyotes. You might find some hayfields or pasture ground where you can find them mousing early in the day.
2. I like to be in the shade with the sun to my back, it is usually overcast here for the larger percentage of the Winter months though.
3. Moving more as they have to hunt harder, they also need to eat more in the cold which is true even for a sparrow.
4. I don't think so. I do think that the sound travels better in the cold air which is to your advantage....Nothing wrong with taking a friend, don't slam the doors once you get there and NO Talking along the way.
You might get one in close but if one circles your location and gets behind you unseen, it will disappear so fast that you won't even know that it was there.
Its open season all year so I want to go at least once a month until I get the hang of it.
A rough sucess average is one predator for every ten calling sites. You can improve on this with techniques gained through experience but it may take you quite a while. It could also be possible that you would get one the first time out!...Don't delay as most of us are hooked once this happens.
