I want to know the answer to the following question:
How many times did Bohemian waxwings come to Britain in the nineteeth century?
All the background I'm provided with is that "Bohemian waxwings Bombycilla garrulus well show this unpredictable variation in annual numbers, with five major arrivals in Britain during the nineteenth century, but 18 between the years 1937 and 2000.". Is that enough to answer the question?
Answer: yes
