The two most studied species, the green catbird and satin bowerbird, have life expectancies of around eight to ten years [10] and one satin bowerbird has been known to live for twenty-six years. [11] For comparison, the common raven, the heaviest passerine species with significant banding records, has not been known to live longer than 21 years ...
As with most members of the bowerbird family, breeding considerations dominate the lifecycle: females nest inconspicuously and raise their young alone, while the males spend most of the year building, maintaining, improving, defending, and above all displaying from their bowers. Only a male with a successful bower can attract mates. [citation ...
The satin bowerbird is the longest-lived passerine with anything approaching high-quality banding data: it is estimated that the average lifespan of the species is around eight or nine years, while the record longevity in the wild of twenty-six years is the greatest for any banded passerine.
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 nest is a loose cup made of small sticks up in a tree. The bower itself is that of "avenue-type" with two side-walls of sticks and usually decorated with green-colored berries. A common species in its habitat range, the fawn-breasted bowerbird is evaluated as Least Concern on the IUCN Red List of Threatened Species.
The western bowerbird is smaller than the other bowerbird it shares its range with, the great bowerbird. It measures 24–28 cm (9.4–11.0 in) in length and weighs 120–150 g (4.2–5.3 oz). Both sexes are similar in size and dimensions, except that the tail of the female is slightly longer. [2]
The nest is a shallow cup made of small sticks located in a tree. The bower itself is of the "avenue" type, with four walls made of sticks and an outward-angled main avenue wall. The scientific name commemorates its discoverer, the German botanist Carl Lauterbach. He discovered this bowerbird in 1896.
The flame bowerbird (Sericulus ardens) is one of the most brilliantly coloured bowerbirds. The male is a medium-sized bird, up to 25 cm long, with flame orange and golden yellow plumage, elongated neck plumes and yellow-tipped black tail. It builds an "avenue-type" bower with two side walls of sticks. The female is an olive brown bird with ...
