RARE SPECIES
Published on March 10, 2008 By Zoologist03 In Wildlife

Well, the first was well received(I got featured, baby. ).  What can I say?  People love animals.  

So we'll continue this little series with Maso's suggestion....

The Bilby! (AKA Rabbit-eared Bandicoot, Greater Bandicoot, Dalgite)  There were two species, the Greater Bilby, Macrotis lagotis  and the Lesser Bilby,  Macrotis leucura.  Unfortunately the Lesser Bilby is now extinct.   The surviving bilby is a threatened species, very threatened.

The Bilby is part of the family Peramelidae which includes all extant(living) species of bandicoots.

Yes, stare into the eyes of chaos!  Okay, it's adorable if very weird looking.

 

Physical Characteristics:

The bilby is about the size of a rabbit. Head and body length: 9–10.2 in(23–26 cm); tail 7.8–11.4 in (20–29 cm). It weighs around 28–88 oz (800–2,500 g).  It possesses very large leathery rabbit-like ears, powerful digging claws, silky blue-gray fur, and a long, thin, snout.  As you can see, the tail has a characteristic black and white color pattern: black from the base to the middle and white from there to the tip.

The claws are only on three toes of the five toes of the front feet. The bilby is a marsupial like all other bandicoots.  The pouch faces backwards and contains 8 teats.

They have a great sense of smell and hearing to compensate for poor eyesight, useful for hunting and avoiding predation.

 

Habitat:

Found only in Australia.  Inhabits desert and scrub land for the most part.  Also found in wooded areas, but without thick ground cover.  It needs a lot of room for foraging.

It was estimated that once the bilby could be found on around 70% of the Australian landmass, but after the Europeans came their numbers were severely reduced due to trapping, introduction of feral species(rabbits, foxes, and cats), and loss of habitat.  They currently exist in fragmented populations across Australia, notably in the Tanami Desert of the Northern Territory; the Gibson and Great Sandy Deserts and Pilbara and Kimberley regions of Western Australia; and isolated areas in southwest Queensland.

Diet:

Omnivorous.  Main foods are various seeds, roots, insects, bulbs, fungi, and fruit.  Local populations have different preferences based on where they live, most likely due to the abundance of a certain food item.  The claws come in handy for finding insects which it laps up with its long tongue- 29-90% of its feces can consist of earth.    They apparently gain all the moisture they need from the food they eat, for they have never been observed drinking water.

 

Behavior:

Nocturnal, venturing out to forage at least an hour after dusk and retreating an hour before dawn.  They are solitary and only observed in groups when an abundant food source exists, though show no social cohesion.  Males will show some territoriality by scent marking, but aggressive behavior towards other males has not been observed.

Bilbies are the only member of their family to burrow and can have up to 12 spiraling burrows in their territory each about 10ft (~3m) long.  It never strays very far from an entrance and can run pretty fast, though a little awkwardly.

Females will mate with the dominant male in the area and give birth after about 14 days to 1-3 young.  This can happen at any time of the year if the female wishes, but is usually limited by food availability and climate conditions.  The young are less than a centimeter in length and will suckle inside the pouch for the next 80 days. After leaving the pouch, the young stay for another two weeks and continue to suckle.  After that, they become independent but may stay in the mother's territory for awhile longer.  The record lifespan for a bilby is is a little over 7 years.

Interesting Facts:

Seeing as how the bilby is in a good bit of trouble these days, a lot of people have been working towards getting the world out on these guys and organizations such as "The Australian Bilby Appreciation Society" have sprung up to help out.

Awareness is also spread around Easter when instead of the bastard feral rabbits, they celebrate with the native bilby.   Also, people sell chocolate to raise funds for the little fellas...appropriately enough, in the shape of bilbies.

Delicious!

 

There is a highly successful bilby breeding program at Kanyana Wildlife Rehabilitation Centre, near Perth, Western Australia.  So action is being taken, which is good.

 

They used to be hunted for food and fur by Aboriginal tribes, but have since become one of the premiere celebrities for Australia's threatened wildlife.

The name "bilby" is actually a borrowed word from the Yuwaalaraay Aboriginal language of northern New South Wales, meaning long-nosed rat.

One bilby tries to save his species, unfortunately the other isn't too fond of that process.

Zoo,

A well thought out, clear and informative report. 

I forgot to mention the Easter Bilby.  It is a campaign that has been run here for a number of years now.  I would love to see it become as popular as normal Easter supplies.

The video footage is cool too.  It is a pity she didn't want to get with the program though.

Thank ya, Maso. It was fun doing it...took about an hour or so to get it all together. I didn't even know this thing existed until you mentioned it.

ATTENTION!!!

Still taking suggestions, so if anyone has an idea, speak up!

Glad to point it out to you. So, now you know about Bilbys, have a look at the Lumholtz Tree Kangaroo, the Spotted Quoll or the Tasmanian Devil, all of which are rare and very interesting animals. Mind you, this is not a suggestion as I don't want to monopolize the pool. I just thought you might be interested.

Lumholtz Tree Kangaroo, the Spotted Quoll or the Tasmanian Devil


The Lumholtz, I'm not familiar with, though I've done a bit of digging on other tree kangaroos...I know a bit about the quoll and the devil. Mostly that those two are really unpleasant.


Not a suggestion, eh? Alright then...we'll see if anyone can come up with something.

Don't be shy guys!

I want a Bilby chocolate!

If you are taking suggestions, the Muennink's Spiny Rat is one of my favorite endangered critters in Japan. Than again, I have a certain fondness for rats.

See? All those cute little furry critters.

But a question for Maso. I do recall the rabbit being introduced into Australia, but cannot remember why. Was it just a pet that escaped? Or put there for a (now) mistaken reason?

And the CHocolate Bilbys are a great idea! Now you need to get a Beatrix Potter to write a cute story about them too (if someone has not already).

The Opposum. The only native North American Marsupial. And a stinky fellow that you do not want as a pet.

Hmm, a spiny rat sounds interesting.   So be it.

If I'm not mistaken, they were introduced on purpose for food.  Basically for trapping so people didn't have to go all the way back to Europe to eat rabbits.  If my memory serves correctly that's why.  Could be wrong though.

Ah, I had to move one of those.  My dog brought one back that wasn't exactly dead...so I picked it up and put it back in the woods.  Not the most attractive animal.  I'll add it to the list.

Cool. I didn't know the Bilby existed. I'd heard of the Gumby, but not the Bilby...

Phrynosoma cornutum!

Texas horned lizard?  Right-O.

I was wondering when we were going to drift away from mammals.

Furry, cute (even the opossum)...so why drift away?

Reptile and amphibians are pretty cool tho. I love geckos and all the wacky, colorful tree frogs.

Weird looking creature, but kinda creepy cute at the same time!LOL!

I wouldn't want to pet it!

 

How about reports on the Mongoose....a fav creature in Jamaica especially since they eat snakes!

And the Humming bird - I've always found them interesting!

Well, furry and cute are nice.(The Opossum is not that cute. ) But I like to explore all aspects of Kingdom Animalia.

Mongoose

Hmm, sure thing.  Added to the list.

Humming bird

That might be long one...there are a crapload of different hummingbirds.

Well, let's see...got a good road ahead of me.

My next projects:

Muennink's Spiny Rat (from ASaxyGirl) (Edit: Done)

Virginia Opossum (from Dr. Guy)

Texas horned lizard (from Roy)

Mongoose (from FS)

Hummingbird (from FS)

Okay, that'll definitely keep me occupied for awhile.   Might try to do one today...we'll see how it goes...for now, it's lunchtime!

Oh, and wouldn't ya know it?  I got featured again!  Hah!  I guess mods really like animals. Almost as much as tech stuff.  

It's much appreciated.

What about house cats?
