OFNC Book Club Winter Pick
Cosy Reading for Cooler Nights In the introduction to his highly acclaimed book, An Immense World, the science writer Ed Yong creates an imaginary scenario with a room full of animals: an elephant, a mouse, a robin, an owl, a bat, a rattlesnake, a spider, a mosquito, a bumblebee, and a human.

Myths, mimicry, and misidentification: Eastern Milksnakes in Ottawa
Text and photos by Jakob Mueller Recently, a report of a “rattlesnake” in a local greenspace got some media attention. The observer reported that the blotchy snake, when found by her dog, shook its tail and made a sound – as a rattlesnake would – so she urged caution. This was a case of mistaken identity, and a particular point of confusion that happens with some frequency in the area. Ontario, being the big and biodiverse place that it is, [...]
