I want to know the answer to the following question:
which bird migrates by circling the earth?
All the background I'm provided with is that "Some species of tubenoses (Procellariiformes) such as albatrosses circle the earth, flying over the southern oceans, while others such as Manx shearwaters migrate 14,000 km (8,700 mi) between their northern breeding grounds and the southern ocean.". Is that enough to answer the question?
Answer: yes
