Land, air and sea

We sometimes get themes in the Bee words. Among others this year, we've noticed a plethora of birds, several plants and some fish. The birds included two that get their name from the sounds they make -- the boobook and the bobolink. Other bird and bird-related words include cormorant, kookaburra, urubu and rasorial. The latter refers to something that scratches the ground in search of food. We've also had plant-related words rhizome, adnate and atamasco. Gudgeon and catalufa are the fish.
