Male bowerbirds are amazing architects, but they reserve theirs skills for just one purpose – finding a mate. They construct elaborate and dazzling nests to impress female.
Male bowerbirds use embellishments such as coins, nails, leaves, shells, seeds, flowers and live insects to weave their nests, called bowers. Bowers are U-shaped nests built with twigs and grass, and carpeted with moss. Each bower is an architectural marvel that stretches out 5 or 6 yards across, complete with a thatched roof and supporting pillars.
Blue is a very important color in the construction process. Male bowerbirds use several blue objects – berries, flowers, bottle caps and string – to attract prospective mates.
Research has proven that females are attracted to bowers with the most number of blue decorations. Because blue objects are rare in a bowerbird’s environment, a male who is able to acquire them and protect them is deemed superior.
