You are wondering if food source alone was driving the pine and oak jay groups to have
different bill lengths. Therefore, you decide to investigate if the jays choose to mate only
with other jays that have the same bill length.
Island scrub jays stay with the same mate for life. You compared the male and female bill
lengths for 42 breeding pairs.
The graph below shows data you collected about the island jays' mating behavior.
