# Big Fans of Feathers

December 30, 2014

One of the coolest things about birds is their feathers. Feathers help birds fly, they keep the bird warm, and in some cases they just look awesome – with peacocks wearing the best feathers of all. Peacocks are famous for their shiny, colorful tail feathers, which can be longer than the bird’s body and can fan out to 10 feet wide. There are 3 kinds of peacocks: Congo peacocks, from central Africa; green peacocks, from southeast Asia; and the Indian peacock, the beautiful blue type we usually see at zoos. You can call both the boy and girl birds “peacocks,” but the girls are actually “peahens,” and the babies are – you guessed it – “peachicks.” Peahens have boring brown feathers, which isn’t much fun, but they need to blend into the dirt to stay safe on their nests, while the boy peacocks show off amazing colors so the girls will want to marry them. On the other hand, the boys have to lug around 5 feet of tail feathers all day, so we aren’t sure who got the better deal.

Wee ones: If a peacock’s tail has blue, green, gold, white and black feathers, how many colors does it have?

Little kids: If a peacock and a peahen have 4 peachicks, how many birds does the family have in total?  Bonus: If each peachick grows up to have 4 peachicks of its own, how many grand-peachicks does the family get?

Big kids: If a peacock is 82 inches long and his tail is 1/2 of that length, how long is the tail? Bonus: The tail can be up to 5 feet long. If the peacock’s body adds another 42 inches, how long is the whole bird in inches?

The sky’s the limit: Peacock feathers have beautiful spots called “eyes,” since they often have a black dot in the middle. If the 1st feather has 3 eyes, the next has 2, then 3, then 2 and so on, is 37 a possible number of eyes the tail can have?
