I want to know the answer to the following question:
Which bird sees more daylight than any other during migration?
All the background I'm provided with is that "Some, such as the black guillemot Cepphus grylle and some gulls, are quite sedentary; others, such as most terns and auks breeding in the temperate northern hemisphere, move varying distances south in the northern winter.". Is that enough to answer the question?
Answer: no
