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.
Bowerbirds collect all kinds of materials for their bowers, from natural items like rocks, flowers, leaves, and berries to human-made objects like charcoal or trash. Some especially artistic ...
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.
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]
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 ...
As opposed to other species of bowerbirds, such as the satin bowerbird, there is no fixed preference for items of a certain colour, more important being the "novelty value" of the items instead, which can lead to fashion-like trends if males find rare or unusual items; such rare finds are prime targets for theft by neighboring males. Females ...
Attenborough heads to Australia and New Guinea. Like the Birds of Paradise, Bowerbird females build their nests and raise their young alone so the male has all day to gather his treasures and create his bower. There seems to be a bowerbird rule: the more elaborate the bower the plainer the bird – the simpler the bower, the more vivid the plumage.
The iconic blue mail collection boxes are a main target of thieves, comprising a significant portion of the more than 25,000 mail theft incidents that occurred in the first half of the 2023 fiscal ...
