The cottontail distress will work year around, so will most distress calls. But you would do best if you had at least a couple of different calls to use. I'd suggest getting something like what North Texan uses, the triple-tone by Circe, that would give ya some different sounds to use and not break the bank, and it is a closed reed call, which means it's easy to use. I'd also suggest buying a good coyote calling video, such as one of Randy Andersons, or the Verminator, or a Byron South video. Not only to hear some instrucational, but more so to hear what the sounds that you should be trying to make should sound like.
