Bird Feeder Data By Julia Rea

This summer, my dad made a birdfeeder for my sister and I. Each day, we watch birds eat from it. I’ve recorded data on which types of birds came to it. Some of the birds that I list, have both male and female. That means that the male and female are sexually dimorphic. Sexually dimorphic is when the male and female have differences in how they look. Others, are not sexually dimorphic. That means, that the male and female look the exactly the same.
