Lesson 9 Culture in the Animal Kingdom
p.133 本文

Dressing Up//
  Chimps and humans are not the only creatures/who like to dress up.// Some birds add material to their feathers/to change their appearance,/much like humans use makeup.// Some vultures rub their heads, necks, and bodies/in iron-rich soil,/which gives them a reddish-brown hue.//
  Bowerbirds in Australia and New Guinea/build elaborately-decorated nests.// Male bowerbirds make entrances (or bowers)/leading to their nests,/decorated with shiny stones, charcoal,/and colorful objects of all sorts,/including bottle caps.// The bowers attract females,/so, after all,/building them may be a matter of instinct.// However,/each bower is unique/and the design changes year by year.//
