The pollen and nectar with which these flowers are loaded attract longnosed and longtongued bats. The bats left Mexico a few days earlier to escape the heat of summer and are on their way north to the southern United States. To get there, they have to cross the Sonoran desert. But the desert is so big that for most of the year they would be unable to cross it. Now, with the saguaro in bloom, they can refuel on the way. So the saguaro' s success in developing a way to store water is now crucial to most of the animals that live or even travel through this land. The scarcity of rain determined the shape of this icon of the desert but water, scarce though it is, has also, like the wind, shaped the land itself. |
