In our own neck of the woods, this final stretch of winter is actually a hot period for a number of species. Fox and coyote are pairing up and mating; the coyote being a little later than fox. And with their sex-drives engaged, I'm hoping to exploit their lust and lure some in for a photo by impersonating a female (this is done vocally - not visually). Howl like a female in estrus and a male just might come running in.
Another notorious winter breeder/nester is the great horned owl, pairing up in January/February. Although the screech owl is a little later in March, I included a photo of a lone male who moved into a friend's wood-duck box. He's waiting for a female to come along in search of a mate with a home. I think this guy's got it going on; I Hope she finds him.
