Sunday Sketch: Aquatic Landscapers keep coral reefs tidy and thriving

While the idiom, “bird brain” may mean a silly or stupid person, we may want to reconsider it as a compliment. Turns out, African grey parrots (Psittacus erithacus) have more abstract logic than the average human toddler. When briefly shown the contents inside two canisters (walnuts or nothing) and then presented the parrots with the…
