I hunt coyotes year' round. I do sometimes take July off, but it's not because I can't call them in then. It's because of all the rattle snakes, mosquitos, black flies, gnats, ants, and other little no-see'ums that feast on a guy while trying make a stand. Real hard to hold still with critters crawling all over you and biting. Hate it. On the ocassional cool day when temps drop down into the 50's. If there is no to little wind I will run out there and try to trick a couple into poking their noses out for a looky-see.
Here are a few summer yotes.
First up a double that I killed at around 5300 feet on a cool summer day.
This one I howled in the evening before while trying to locate for the next day. Unfortunately I did not have a gun with me and just had to watch helplessly as the coyote milled around in front of me at 200 yards. Went back in the next day and called her right in. I had my daughter along as I had a pretty good idea this aggressive coyote was going to cooperate. She came charging into a jackrabbit sound the following evening. I wish all plans worked this well.
Got this last one just minutes before a heavy duty thunder storm rolled in. I literally ran back to my pick up. Jumped inside and even before I could start the pick up engine the first rain drops hit the windshield. It quickly turned into a major nasty storm. I couldn't have been more lucky or timed it any better. Man, I'm glad I wasn't running back to the truck when the lightening started up. Running in a lightening storm with an AR strapped to my back is not my idea of a good time!
