You load sixteen tons, and what do you get?  This Rock Kestrel of course!  But he’s no mere “miner’s canary.”  As a star coal miner, he’s hauled many a minecart through the tunnels with his mighty wings (one wing of iron, the other of steel), and his tiny helmet lamp.  I guess this bird of prey only preys upon wayward coal nuggets that need extracting!
