When I leaned my pruning pole against one of the tree's two leaders, I noticed a good half of the trunk riddled with holes a quarter inch deep, not random drillings but repetitive horizontal patterns circling the trunk. The perforations gave the appearance of one large cribbage board. When I first saw these markings, I was reminded of a beetle infestation that killed my two pie cherry trees years ago. Unlike the bored holes dribbling sawdust, these indentations have scabbed over and the tree appeared to be no worse for the poking.
I've seen these holes before on our walnut tree but hadn't noticed the intricate dotted artwork on the apple tree prior to this year's pruning. The holes are the artistic work of a species of woodpecker: the red-breasted sapsucker (Sphyrapicus ruber). With engineer-like precision the bird does its artwork, then returns to slurp the sap and dine off any insects that might be attracted to the syrupy watering holes.
After a bit of research I learned a sapsucker's sap mining can be so aggressive the host tree dies. Even though this stately old apple is a canker victim and now riddled with hundreds upon hundreds of holes, it's a survivor. Come mid-summer I have no doubt the tree will again bear enough fruit to fill this winter's applesauce quota.
This sapsucker business has me puzzled. It must have taken some time for the bird to perforate the bark countless times. I assume the species is not nocturnal, and therefore it seems I should have seen it drilling away as it circumnavigated the trunk row after row. Yet I've never seen its redheaded eminence bobbing about the trunk. In fact I've only seen the species once, and in the attached photo it clings to one of our fir trees out front. One more thing: the bird is a "sapsucker," right? Therefore it must do its work when the sap flow is most abundant, which, I assume is in the spring. Thus the window of time for sapsucker watching must be limited to just a few short weeks in spring and still, I've yet to see the perp.
So now in addition to having a food source growing out back, I also have an entertainment center. If you're up for a game of cribbage, let me know. I'll furnish the cards, but you'll need to bring your own ladder.
