Whether it's a flamboyant of flamingos, a parade of elephants, or a dazzle of zebras, being part of a group has its advantages for defence and bringing up babies. A Chilean flamingo chick is a grey puffball, taken care of by both mom and dad from the time the egg is laid. Mom lays only one egg in a season, so his survival is important. Eurasian tundra reindeer calves are able to walk within an hour after they are born. At a zoo in Winnipeg, they stay with the herd as they would in the wild, and drink rich milk from their mom for the first month. They shed their heavy winter coat in spring, and males shed their antlers in fall while females shed them in spring. Elephants have a lot of common with humans. They take a long time to grow up and they live in social groups. In the wild, baby elephants may be part of an all female herd which nurtures her and teaches her how to raise calves of her own. Calves play all day, but if they get too rowdy, an adult will discipline them. They communicate vocally, sometimes with sounds too low for us to hear. Their trunks work as a nose, a hand, a voice and a straw, all in one. Baby zebras can also walk soon after they are born. Chapman zebras graze in the wild in Africa in herds, for greater safety from predators, with wildebeest as their travelling companions. Big family groups are important for the survival of many types of animals.
