Maria wanted to learn more about the birds that visit her backyard. She installed several bird feeders and offered the same variety of bird seed mixes in each feeder in order to attract a mix of bird species. For a month, she observed the bird feeders three times a day for an hour each day and counted the types of birds that visited the feeders. Then, she made a pie chart to compare the numbers of birds of each species that visited the feeders. What is the most likely reason that she chose a pie chart? To show the total number of birds that she observed. To show the number of times that each bird visited the feeders. To show which bird species were most common. To show how the bird species changed over time.
