I want to know the answer to the following question:
What birding event does the Audubon Society host every year?
All the background I'm provided with is that "San Diego always scores very high in the number of bird species observed in the annual Christmas Bird Count, sponsored by the Audubon Society, and it is known as one of the "birdiest" areas in the United States.". Is that enough to answer the question?
Answer: yes
