bird peck
n.— «Sapsuckers are unwitting heroes to many creatures, but in the eyes of the timber industry, not so much. Timber people hate sapsuckers because they feel the birds damage the trees (unlike them, who only cut the entire tree down). They even have a name for lumber that has sapsucker damage. It’s called “bird peck.” Really, it is. That’s a rather cute name coming from guys who carry chain saws all day long.» —“Sapsucker is the culprit” by Mike O’Connor Harwich Oracle (Orleans, Massachusetts) Jan. 31, 2007.
