Visiting the Largest Bird Ever to Have Lived

Mommy, Logan and Delenn have been going to the Strehlow museum (Strehlow Research Centre) every two or three weeks. It's located just one block from where we live. It has a wonderful display of lizards, snakes, spiders and various mammals. It also has some meteorite fragments and skeletons from extinct and non-extinct animals.

Below is a picture of Logan with the largest bird ever to have
lived--the Dromornithid. The biggest bird ever to have lived was a
DUCK! Read the excerpt below...

For more than a century scientists have been misled by the size of the
biggest bird to have ever lived, the extinct Central Australian
Dromornis stirtoni who stood 2.5 to three metres tall, into thinking
that it was a probable ancestor of present day ratite birds, ostriches,
emus and cassowaries. New finds at the Alcoota fossil site north east of
Alice Springs, have turned that theory on its head: the big bird is
actually the grandaddy of ducks and geese.

One good thing about the Dromornothids (and others) was that they were
able to eat very poor quality vegetation which they recycled into great
dollops of dung, high in nitrogen and other nutrients, dropping them
across the countryside. This helped replenish the environment. Once
these giant ducks were gone there were only termites left to recycle
this vegetation back into the system.

Another interesting fact: There were 10 to 15 species of big kangaroos,
up to TWICE the size of the red kangaroo, as recently as 20,000 years
ago, and that many other browsing forms once roamed this region.
