Count and record the beans obtained by each plover. Compare the results with those of the first round. Discuss the number of beans obtained. Ask the plovers how they feel physically. Explain to the students that when people leave trash in an area, it attracts other kinds of animals like cats, raccoons, skunks, foxes, and gulls.
Gulls are fast moving birds that prey on piping plover eggs and chicks.
If both adults are present, the second parent will lead the chicks to safety. Because they are unable to fly, chicks are easy prey for gulls. Throughout this round, chicks should be squatting on the ground while the adults remain standing. This distinguishes between the adult's ability to actually flee from a gull by flying away and the chick's inability to fly or move fast enough to escape. Assume that adults are parents feeding with their young chicks.
