iz Instructions Question 1 1 pts You test whether the hummingbirds in your yard prefer red colored feeders over blue colored feeders by setting up 3 red colored feeders and 3 blue colored feeders, each at separate locations in your large backyard. You set up motion-activated cameras to film each feeder for a 3 hour period. Later you watch each film and count the number of times an individual hummingbird fed from a feeder, keeping note of the color of each. On average, hummingbirds used the red feeders 45 times and used the clear feeders 35 times. This is clear evidence O That hummingbirds visit feeders more often if they are filmed That hummingbirds prefer to use red feeders That there is not enough information to determine a preference That hummingbirds show no clear preference for feeder color NextExplanation / Answer
Option 'c' is the correct answer.
The number of visits to red feeders is considerably more than the number of visits to the blue feeders. This is clear indication that hummingbirds prefer to use red feeders. This is because the hummingbirds' sense of color is due to the dense concentration of cones in its retina. The cones themselves contain pigments and oil droplets in shades of yellow to red, which seem to act like filters. The filters appear to heighten color sensitivity in the red to yellow range, while muting colors such as blue.
