Document Summary

Migration, communication, cost & benefits of social interactions, mating & kinship, and eusocial organisms. Migration: the predictable, seasonal movement of animals from an area where they were born (their natal location) to a distant and initially unfamiliar destination. Migrant populations return to their natal site: habitat selection, 3-4 months out of a animals year. Easier to raise their babies in warm water but they have less productive water there so they migrate back to places like canada in the summer where water is more productive. Piloting: using familiar landmarks to guide the way. (whales actually do this. When they go south in the winter they are close to the shoreline to landmark the mark the land to see where they are going and how to come back. Compass orientation: moving in a particular compass direction (e. g. north or south) based sensing of the sun or earth"s magnetic field: usually used by smaller objects.
