Natural history

Murky, rainy day…so this photo is from one year ago, on a much sunnier day…although you can’t quite tell that. Trust me.

I just read a NYTimes article reporting that bears rub up against trees so that the tree-bark resin/sap gets in their fur and acts as a tick repellant. These bears are I’m not sure where, but it seems rather northern, like Poland, and the trees include beech trees.

I hypothesize this model doesn’t work for southern bears, as leaning against southern trees (e.g., pines) is a good way to get chiggers. Now chiggers are not ticks, but, personally, I’ll take neither…critter infestations of the skin are…ick, yuck, and no thanks.
