I want to know the answer to the following question:
What kind of birds fly low over water?
All the background I'm provided with is that "Bar-headed geese Anser indicus have been recorded by GPS flying at up to 6,540 metres (21,460 ft) while crossing the Himalayas, at the same time engaging in the highest rates of climb to altitude for any bird.". Is that enough to answer the question?
Answer: no
