The Underground Highways

New study uncovers how animals in Maryland use underground highway culverts

An interesting article about how animals use culverts to cross roads that otherwise might isolate populations.  The cool thing, from my point of view, is that different animal prefer different types of culverts:
Ranging from 2 feet to 15 feet around, culverts can be shaped like arches, concrete boxes and corrugated metal cylinders –- and it makes a difference, the study found. For instance, raccoons had little preference for which kind of culvert they chose for travel, but deer wouldn’t go near tunnels with cobbled floors. Eastern gray squirrels were not found in any arch-shaped culverts. Domestic cats seemed to take a liking to the cylinder-shaped tunnel. And great blue herons used the box shape more often than thought, most often when the bottom was sandy.
I wonder what Sasquatches prefer?
