Question

Why does the author include the numbers of birds sighted In recent “big years”?

Answer 1

The author included the numbers of birds sighted because  the reason for that was because since it refers to an effort to see as many birds species as possible within a specific area during  a calendar year.

* HOPE THIS HELPS :)

Answer 2

Answer:

I would say A or C.

Explanation:

Reason to why not B and D: The "big years" is not about finding the most birds so I'm not sure why the author would want to imply that the records can easily be broken/are meant to be broken.

Not to mention a quote from the text is "..winner managed to see 744 birds in one year"

Thats a lotta birds.

I'm doing the test right now but I wanted to help, ima go with A and if its wrong I'll give you guys an update.

EDIT: Okay its A! I turned it in and I was right! :)
