“Let us now apply this logic. Borbs as a category heavily intersect with birbs, defined as both are by roundness. But just as every bird is not a birb, every birb is not a borb. Some birds naturally have deep chests and short necks, easily securing their borbness: chickadees, European Robins, and Bearded Tits, the last of which seems to be the poster child for the type. Other clear borbs include pigeons, thrushes, warblers, game birds, small parrots, most owls, and penguins.”
