Question

What names we can give to a group of students who are working on the declining population of sparrows?Please give the reason for the group name you suggest.

Answer 1

You can name then "Fauna Police" or "Sparrow Police". 
Fauna means Animal. As they are working on the declining population or death of sparrows, you can call them police. It matches with our common sense.

Btw, I like Fauna Police.
