Who doesn’t love peanut butter? And a graphic depiction of that classic of all classic combinations, the P.B. and J. that we all grew up eating, became a familiar sight at Minnesota’s Sax-Zim Bog last week with a slight modification to the “J.”. In Sax-Zim Bog the “J” was neither jam nor jelly but rather a Jay, a Canada Jay to be exact. All the birds seemed to love the generously slathered globs of peanut butter on logs and perches and specially crafted feeders. The temperatures were usually well below freezing so that peanut butter did not melt and the birds severed chunks of it with their beaks. They came back for more peanut butter over and over so apparently swallowing was not a problem for the birds. No milk needed to wash it down.
