Last night, while on the walkabout at work, I heard a scratching sound, which drew my attention to one of the neighbors:
In the middle of the frame, in the flashlight's beam, you can just make out a face belonging to a North American opossum (Didelphis virginiana). Unfortunately, the tree branches made focusing on the 'possum's face impossible. 'Possums, along with the nine-banded armadillo and the North American porcupine, are the best-known "Southern" survivors of the Great American Faunal Interchange, with the opossum being the only marsupial living in North America. Our opossums don't hibernate, which is unfortunate, because it started snowing heavily soon after I took this picture. I will make sure to check the vicinity again tonight to see if I can find the little beastie.
North American opossums are famed for engaging in defensive thanatosis, feigning death in response to perceived threats, to the extent that "playing 'possum" is a colloquial term for feigning death or unconsciousness. This particular survival strategy is occasionally employed by other mammals.
