I want to know the answer to the following question:
What do water birds avoid while migrating?
All the background I'm provided with is that "Detours avoiding such barriers are observed: for example, brent geese Branta bernicla migrating from the Taymyr Peninsula to the Wadden Sea travel via the White Sea coast and the Baltic Sea rather than directly across the Arctic Ocean and northern Scandinavia.". Is that enough to answer the question?
Answer: no
