Bower birds

Je veux vous presenter un animal un peu plus marrant que les menacants brwon snakes, funnel web spiers or red back spiders...and sharks...an blue bottle fish.

Non.

Dans la foret d'Otford nous avons la chance d'avoir des Bowerbirds.

'MALE BOWERBIRDS ARE well-known for the elaborate constructions they create to attract a mate. Now it seems that these constructions do more than look good - they could be designed to actually make the male appear bigger and more attractive to the female. 

Great bowerbirds create a long tunnel-like 'avenue', usually about 60 cm long, using two walls and a floor of tightly packed sticks. Just outside each entrance to the avenue is a bower 'court', an area covering about 1 m x 0.5 m.

Much like a queen watching a court jester, a female sits inside the avenue observing the male display in the court. He parades his turquoise-blue crest and presents coloured objects by waving them in the direction of the female.

The males line the courts with various items - usually grey to white objects, such as shells, bones, and even wasps nests - on which they put the coloured objects, like fruit, glass and plastic. They'll happily use man-made materials alongside natural ones.''
