Two experiments were conducted. After the females had been given ample time to view the males, the small flowerpot was removed (in the first experiment) and the low oxygen water pipe turned off (in the second experiment). The female was then given access to the entire aquarium and allowed to inspect the inside of the nests for the first time. What she saw was that both males had identical nests-10cm wide flowerpots with normal oxygenation. Yet, in the first experiment, 82% of females first chose the male who initially had the larger nest. In the second experiment, 73% of females first chose the male who initially had low-oxygen water piped into his nest earlier. What explanation do you have for these results? How were females able to perceive differences in nests that they could not see, and why did they make the choices that they did?
