About the theme

Forest Wildlife runs the European and North American forest set — fox, badger, owl, hedgehog, raccoon, beaver, deer, elk. The longer entries (woodpecker, squirrel, opossum, porcupine, chipmunk) anchor every grid they fit on. The filler leans on common consonants because forest creatures' names mostly run plain Anglo-Saxon — the result reads like a forest walk in print. Smaller grids carry the four-letter set (deer, bear, fox, hawk); bigger grids open up the full taxonomy.
