A. Introduction
When taking a hike, you notice that a ruby-throated hummingbird seems interested in your red hat. It hovers over the hat then darts away. Do ruby-throated hummingbirds prefer some colors more than others when visiting flowers? Through an investigation into this scenario, it has been found that ruby-throated hummingbirds can in fact be attracted to red and even orange colored flowers (Mayntz, 2011). According to Vermont Fish and Wildlife, ruby-throated hummingbirds are attracted to trumpet shaped red flowers and will also feed on artificial feeders with red tubes made to look like the flowers they visit.

The experimental variable will be the color of the hat worn. One subject will wear a red hat, one will wear a green hat and the last will wear a black hat. They will walk with red on the right, green in the middle and black on the left. Over the course of the three days, results will be recorded based on the attraction of the hummingbirds to any of the colored hats. E....
