Chlamydera, Sericulus and Ptilonorhynchus bowerbirds build an avenue-type bower made of two walls of vertically placed sticks. [14] Ailuroedus catbirds are the only species which do not construct either bowers or display courts. [15] In and around the bower, the male places a variety of brightly colored objects he has collected.
Like all bowerbirds, the satin bowerbird shows highly complex courtship behaviour. Mate choice in satin bowerbirds has been studied in detail. [ 7 ] Males build specialised stick structures, called bowers, which they decorate with blue, yellow, and shiny objects, including berries, flowers, snail shells, and plastic items such as ballpoint pens ...
The spotted bowerbird (Chlamydera maculata) is a sedentary, mid-sized passerine found across broad parts of the drier habitats of eastern Australia. The species is known for its remarkable behaviours, like many other bowerbirds (Ptilonorynchidae), which include bower building and decorating, courtship displays and vocal mimicry.
The regent bowerbird (Sericulus chrysocephalus) is a medium-sized, up to 25 cm long, sexually dimorphic bowerbird. The male bird is black with a golden orange-yellow crown, mantle and black-tipped wing feathers. It has yellow bill, black feet and yellow iris. The female is a brown bird with whitish or fawn markings, grey bill, black feet and crown.
The great bowerbird (Chlamydera nuchalis) is a common and conspicuous resident of northern Australia, from the area around Broome across the Top End to Cape York Peninsula and as far south as Mount Isa and Townsville. Favoured habitat is a broad range of forest and woodland, and the margins of vine forests, monsoon forest, and mangrove swamps.
Molecular evidence suggests Ailuroedus is a sister group to the other bowerbirds, diverging into the only genus within the eight species of Australian bowerbirds that is monogamous and does not build a bower or clear a court for mating. [3] [4] The other bowerbirds are polygynous and make various forms of bowers or create stages for mating. [5]
On "The Daily Show," LeVar Burton pointed out how ridiculous the book ban efforts in the U.S. are getting.
Satin Bowerbirds: bowerbirds are famous because of their complex male courtship, in which they utilize decorations of certain colours. [105] This suggests that male bowerbirds with enhanced cognitive abilities should have a selective advantage during male courtship. [ 106 ]
