Alas. Invasive jackhammer colonies are generally protected by a whole slew of laws, starting with the well known Mulligan act of 1939, which originally only protected the feeding and habitats of steam shovels, but which, with further environmental action, see the Decepticons et. al vs. section of any mid 80's law text for the seminal citations, and continuing to this day with ongoing efforts to increase suitable habitat and reintroduce this endangered species to urban areas.

Encouraged by the success of jackhammer rehabilitation in urban areas concerned citizens have successfully campaigned to reintroduce the red tail hawk here in Manhattan. All efforts have been extremely successful, but no one anticipated the sheer size of the current breeding population. Jackhammers that is, not hawks, though it is nice that they can cohabit.

I'm glad you had such a good day. The exhibit sounds great.
