...!...?

I thought this might be an apt post to follow my poem on the ecology of the redwood forest canopy: out for a wander with my camera recently, I came upon this scene of mystery. It was in an area where the undergrowth is managed, was cut back, almost to a non-existence last year, though you'd not think so now. As can be seen from the photographs, a silver birch has been snapped off a few feet from the ground. A broken section of a silver birch trunk is leaning against a third tree. But what really took my eye was a second section of silver birch trunk, also clearly broken-off (as opposed to sawn or axed, for example), perched vertically, and very precariously, on a branch of the third tree. Neither of these sections, I think, could have come from the broken trunk still in the earth as they are both thicker than it. Neither could I find any other broken silver birch trees. The first reaction was to think that maybe some local lads had been having a lark, but there was no sign that the vegetation, thick around that particular tree, had been trampled or otherwise disturbed. Thinking of the likely weight of the elevated trunk section also seemed to argue that larking was an unlikely cause. Maybe, I conjectured, the said trunk had been tossed there by a fugitive from the Highland Games... but then I thought: just one way to resolve this, that lot from blogland are all more imaginative than I. So, any suggestions?
