Bio-what? Good question. We find out, via mining in the article circle and the age old question "how many chaffinches equals one owl?"

Also this week, bees related babble, a model Inhofe, and Arabella pronouncing a complicated word that Dave cannot.

Music by Dicky Moore from Bearcraft and Dream Themes.
