the migratory routes are from California beaches too Japan and back every year
routes of migratory birds
I was taught in college that some animals, such as birds, geese, are guided by magnetic forces, not forcing them to go this way, but guiding them
They Both Go North And South
Research homework question.
in winter they travel inland some 600 miles and then in summer the females head for the coast to get food for the young
Trappers opened routes to Alta California to find new areas that had fur animals to trap. They discovered new routes while looking for new places to trap beavers and other animals.
Because they were farmers not hunters. Farming led to more permanent structures. Hunters required shelters that could be packed up and moved to follow their prey along their migratory routes.
migration of animals movements of animals in large numbers from one place to another. In modern usage the term is usually restricted to regular, periodic movements of populations away from and back to their place of origin. A single round trip may take the entire lifetime of an individual, as with the Pacific salmon ; or an individual may make the same trip repeatedly, as with many of the migratory birds and mammals. The animals may travel in groups along well-defined routes; or individuals may travel separately, congregating for breeding and then spreading out over a wide feeding area, as do some of the seals .
Avoid typical migratory routes (requires doing research) Don't fly at a level where a bird can hit you (pretty hard to do) Best way: don't fly aeroplanes. saves tons on fuel, too.
It depends on the temperature of the area and where the food is. So in winter for example, whales migrate and breed to an area where it is warm and feed their young until they are old enough to fend off for themselves. Than they go back to their original homes.
By splitting up they were able to see much more of the territory and to discover more plants and animals.
