Secret life of the dodo revealed

Scientists are piecing collectively clues about the existence of the dodo, loads of years after the flightless hen turned into pushed to extinction.
Few scientific statistics are recognised about the hapless bird, which became last sighted in 1662.
A examine of bone specimens indicates the chicks hatched in august and grew hastily to adult length.
The chook shed its feathers in march revealing fluffy grey plumage recorded in historical bills with the aid of mariners.
Delphine angst of the university of cape town, south africa, turned into given get right of entry to to a number of the dodo bones that still exist in museums and collections, consisting of specimens that have been recently donated to a museum in france.
Her group analysed slices of bone from 22 dodos underneath the microscope to discover extra approximately the hen's growth and breeding patterns.
"earlier than our take a look at we knew very very little about these birds," said dr angst.
"the usage of the bone histology for the first time we managed to describe that this chook became surely breeding at a sure time of the yr and was moulting simply after that."

Reconstruction of the dodo: a lot of what we recognise from art work is wrong
The scientists can tell from boom styles in the bones that the chicks grew to grownup length very hastily after hatching from eggs around august.
This will have given them a survival advantage when cyclones hit the island among november and march, leading to an absence of meals.
But, the birds likely took numerous years to attain sexual adulthood, probable because the person birds lacked any natural predators.
The bones of person birds additionally show signs and symptoms of mineral loss, which shows that they misplaced vintage broken feathers after the breeding season.
Historical mariners gave conflicting accounts of the dodo, describing them as having "black down" or "curled plumes of a greyish color".
The research, posted in clinical reviews, backs this ancient proof.
"the dodo become quite a brown-grey fowl, and at some stage in the moulting it had downy, black plumage," defined dr angst.
"what we observed the use of our clinical strategies match perfectly with what the sailors had written within the past."
Egg theft
The studies may also shed mild on the dodo's extinction approximately 350 years in the past, less than 100 years after people arrived at the island.
Looking was a component inside the dodo's demise, but monkeys, deer, pigs and rats released on the island from ships probable sealed their fate.
Dodos laid their eggs in nests on the floor, which means they had been at risk of assault by way of feral mammals.

Dr angst said the dodo is taken into consideration "a totally massive icon of animal-human induced extinction", although the whole information are unknown.
"it is hard to understand what become the actual effect of people if we don't know the ecology of this chook and the ecology of the mauritius island at the moment," she defined.
"so this is one step to apprehend the ecology of these birds and the worldwide atmosphere of mauritius and to mention, 'ok, when the human arrived what precisely did they do incorrect and why did these birds have become extinct so fast'."
Julian hume of the natural records museum, london, a co-researcher on the observe, stated there are still many mysteries surrounding the dodo.
"our work is displaying the seasons and what became honestly affecting the boom of those birds due to the climate in mauritius," he stated.
"the cyclone season, when frequently the island is devastated with storms - all of the fruits and all the leaves are blown off the trees - is quite a harsh period for the fauna - the reptiles and the birds on mauritius."
The dodo, that is associated with the pigeon, advanced on mauritius.
However, bone samples are rare, making it difficult to hint the evolutionary method.
Despite the fact that many specimens of the dodo ended up in ecu museums, most were misplaced or destroyed inside the victorian generation.
