Salt Lake City, Utah	yes
Winston-Salem, North Carolina	yes
Ames, Iowa	yes
Bluford, Illinois	yes
Bangor, Maine	yes
Winter Park, Florida	no
Elwood, Nebraska	yes
San Antonio, Texas	no

Percentage of feeders reporting American Goldfinches

_{percent =} 8 Sites visited X 100 ₌ 80%
10 Sites

Example 2. The same classrooms are participating, but this time you figure out what percentage of feeders were visited by Scrub Jays.

Lancaster, Pennsylvania	no
Salt Lake City, Utah	yes
Winston-Salem, North Carolina	no
Ames, Iowa	no
Bluford, Illinois	no
Bangor, Maine	no
Winter Park, Florida	yes
