Awe-inspiring animal migrations that send people flocking
Animals migrate to breed, feed, mate, and various other essentials to survival

There is something magical about animal migrations. Perhaps it’s the fact that as more of us move to cities (The U.N. predicts that nearly 70% of the global population will be urban dwellers by 2050), the sight of congregating herds, schools of fish, or flocks of birds is increasingly rare. Or maybe witnessing animals cross great distances to eat, mate, breed and, in essence, survive helps us to take stock of our own lives. Whatever the reason, when animals come together, very often so do humans. Here’s our guide to the animal migrations that bring people out in flocks.
Residents of Pacific Grove, California, take their butterflies very seriously. The area offers a warm micro-climate that attracts 20,000 monarch butterflies who travel up to 2,000 miles to winter in the region. In fact, the annual phenomenon has earned Pacific Grove the nickname “butterfly town”.
“I always hear that the monarchs are coming before I ever see one. I get emails saying, ‘I saw my first monarch of the season!’ Everyone wants to be the one to herald their return,” says Lori Mannel, executive director of the Pacific Grove Museum of Natural History. The season sees an influx of tourists as well. During the winter months, nearly 100,000 visitors come to witness the spectacle.
The last few years has seen a drastic decline in their population, a fact some credit with the degradation of milk weed — the only flora monarchs can lay their eggs on. To help restore the population, many locals have started replanting the stuff, while the local government has instilled a $1,000 fine for disturbing a monarch.

Run, sardine, run
The east coast of southern Africa bears witness to one of the greatest migrations of all time: the sardine run. From May through July, millions of sardines spawn in the Agulhad Bank and make their way north up the coast.
The migration also attracts predators, both of the human and animal variety. Each year, thousands of locals and tourists perch with massive fishing nets to catch the unwitting fish. Joining their ranks are sharks, dolphins and gannets, who also hover nearby in the hopes of snagging an easy dinner.

Sign of the wildebeest
While tourism isn’t always a welcome phenomenon for environmentalists, there are some instances where conservation efforts are abetted by traveler interest. In the Serengeti, for instance, the tens of thousands of visitors that stream in July and August for the Great Migration (so called for the millions of wildebeests that trek from Tanzania to Kenya) actually help to ensure funding goes to conservation.
“You could argue that tourism is one of the major reasons this huge ecosystem still exists today,” says Craig Sholley, the vice president of philanthropy and marketing at the African Wildlife Fund.
At the peak of the migration, the banks of the Grumeti River are lined with hundreds of vehicles packed with environmental voyeurs all eager to glimpse the beasts make the life-threatening swim across the currents.
