I want to know the answer to the following question:
Until what year did the belief of hibernating birds persist?
All the background I'm provided with is that "However, he also writes that "as to swallows being found in a torpid state during the winter in the Isle of Wight or any part of this country, I never heard any such account worth attending to", and that if early swallows "happen to find frost and snow they immediately withdraw for a time—a circumstance this much more in favour of hiding than migration", since he doubts they would "return for a week or two to warmer latitudes".". Is that enough to answer the question?
Answer: no
