Here in the Niagara Peninsula I see lots of big old trees with sapsucker 
holes in them.

I understand that the sapsuckers tend to dril more holes than they can 
defend, and the hummingbirds (especially before many flowers open) and 
to some extent orioles raid the sap holes.

Human sap tappers are apparently only a small risk to the health of 
maple trees.
