One universal thing about kids -- they always want to know "why?" This inquisitiveness is the focus of this episode. The program looks at bees (there are more than 30 native Sonoran Desert species) and their critical role in pollination of desert plants. Also, you're in the operating gallery as scientists perform surgery on a black tail rattlesnake in order to implant a radio-tracking device under its skin. Learn how the Mexican Jay has a highly sophisticated and social fashion of rearing its young -- part of new research on monogamy and polygamy and the study of social structure among desert animals.
