You Know The Drill


Day 41: You know the drill...or do you? Can you identify who's been pecking your trees by looking at the holes? Red-Breasted Sapsucker (frequently misidentified as a "red-headed woodpecker" by novice birders) typically drills horizontal lines of evenly spaced holes as shown in the image on the left. Contrary to common belief, Sphyrapicus ruber can't be blamed for killing trees. These birds are drawn to wood which has already been weakened by other stresses (disease, drought, detrimental bugs). Although the name suggests that these birds might feed exclusively on sap, it has been shown that they often drill holes without feeding, and return later to dine on the insects which are drawn to the exudate. Sapsucker likes his bugs sweetened!
