Albert's Lyrebird
Species Common,
Scientific Name, and Classification
The Menura alberti is a small ground dwelling bird that is
rare and only lives in Australia. It is known by three common names Albert's
Lyrebird, Prince Albert, and the Northern Lyrebird. The taxonomic classification
of this bird is as follows Menuridae: Passeriformes: Aves: Chordata: Animalia.

Range and Habitat
This bird is not threatened but is listed as rare and
vulnerable by the Australian Government Department of the Environment. It has
one of the smallest distribution ranges of any bird in Australia. It resides
only in a small section around the border of far south-east Queensland and far
north-east NSW. It does not ever leave this area because it does not migrate to
breed. Within these ranges it is not
evenly distributed. For example, Small groups of birds will live in one area of
the overall range and other groups will isolate themselves in random other
parts of the range. This random distribution means that there is not expected
to be much gene flow between the small populations. Because of this and the
small range that they live in a threating environmental event could be enough
to completely wipe out entire populations or the species. The population of
this bird has been decreasing since European settlement. Most of its habitat
was cleared in the 19th century, but there has been continued
development of its habitat and the bird is being forced to move to higher
altitude forests. Therefore, most of its habitat today is only in nature
reserves. As long as these areas are maintained the Menura ablerti’s
populations numbers are not expected to drop dramatically. (http://www.environment.gov.au/cgi-bin/sprat/public/publicspecies.pl?taxon_id=652)
These birds like to live in a very wet environment. As a
result, They live in the wettest rainforests wet sclerophyll forests with a wet
understory. They prefer these rainforests to have a eucalypts canopy and in the sclerophyll forests they like large
amounts of leaf litter. (http://www.environment.nsw.gov.au/threatenedspeciesapp/profile.aspx?id=10525)
Physical Description
and Image
The females are approximately 75 cm in long and males 90 cm long. They are chestnut-brown
in color and have a brownish-red on the bottom of their tail, hindquarters, and
throat. A tail display is used to attract females. The male flips and spreads
its tail over its body and head. Not only does the male use the positioning of
the tail to win over females the colorations and types of feathers on the tail
also play a role in this. The male has two outer feathers that are black and
broad; they have bushy filamentaries which are black and silvery, and two long
slim ribbons. All this aids in attracting the females. For females the tail is
not important for mating therefore its not several colors and is not as long as
the males. (http://www.environment.nsw.gov.au/threatenedspeciesapp/profile.aspx?id=10525)
Behavior
The Albert's Lyrebird is a shy bird. They are not commonly seen
by people but they are often heard by the males. This is due to the males
mating call and their mimicking of other birds call. The territories usually
contain 5 to 15 birds but it is typical to only fine one or two together at a
time. Because they like to be alone for the most part they don’t move location
much through the year. They build domed nests either 2 to 5 meters up in a tree
or up on rock ridges. The egg has an incubation period of 42 days. https://www.ehp.qld.gov.au/wildlife/threatened-species/near-threatened/alberts_lyrebird.html
Conservation Status
The Species is listed as near threatened. It is not a top priority
on the Department of Environment and Heritage Protection list. The bird is not
a big priority because the species has been stable. There are actions being
taken to further protect the species. Even though the numbers are stable the
general population is so small that one natural disaster could be detrimental
to the species and it could possibly not recover. https://www.ehp.qld.gov.au/wildlife/threatened-species/near-threatened/alberts_lyrebird.html
The conservations actions that are currently in effect are a
study of the habitat distribution and population density, the Whian Whian State
Forest and the Eucalyptus plantations are now protected, state forests are
being turned into national parks, and finding actions to enhance the quality
and level of the habitat. http://www.birdlife.org/datazone/speciesfactsheet.php?id=5161
Ecology
Albert's Lyrebird live in wet forests above 300m with thick
understories. They like poorer soil qualities because they look for food in the deep leaf litter on
the forest floor. http://www.birdlife.org/datazone/speciesfactsheet.php?id=5161
They eat invertebrates that live in this soil and deep
leaf-litter. They particularly feed on insects and their larvae. http://www.environment.nsw.gov.au/threatenedspeciesapp/profile.aspx?id=10525
