Natural Gas Powered Owl

From Daniel Ardnt

Learning time! Why on earth would a white bird perch so obviously on a black, man-made structure low to the ground? It's all about thermal efficiency! The natural gas flowing through the pipe, and the black material that wraps around it, are both heat sources for these birds. While the temperature isn't too cold right now in Calgary, saving even the smallest amount of energy is critical to their overwintering success.
