I read that article and had to do a double take , I have been calling coyotes for quite a few years now and ill flat tell you when there is a full moon they are not as active in the daylight hours.Not saying you cant call one up but the percentage of called in coyotes per stand goes way down . maybe in another part of the country this does not hold true( I doubt it makes and diff.)
Think about it a full moon allows them to see and hunt much more sucessfully , They party all night and when dawn comes they go bed down with full bellies .
I dont even waist my time on full moon days unless i HAVE to .
Most coyotes i have called in on a full moon seem to respond best slightly before or after noon , So if your gonna call on a big moon might just as well sleep in a little . jerry
