I want to know the answer to the following question:
How much of the bar-tailed godwits bodyweight is stored as fat before migration?
All the background I'm provided with is that "Some bar-tailed godwits Limosa lapponica have the longest known non-stop flight of any migrant, flying 11,000 km from Alaska to their New Zealand non-breeding areas.". Is that enough to answer the question?
Answer: no
