Dodos

A variety of things might have helped

If they could fly

If they had predators, and had learned to be wary of the new arrivals on their island (European humans!)

They weren't confined to one location - Mauritius.

Because all birds are animals (not plants).

Not known very definitely. The last confirmed sighting was in 1662, but there were contested sightings as late as 1674. Statistical analysis of the numbers of birds taken in hunting expeditions suggests a curve descending to zero in about 1693. The dodos were not literally hunted to extinction by humans, but they were also killed by introduced rats, dogs, cats, and monkeys (most of which ate the eggs and nestlings, rather than the adult birds). Therefore, the last dodo killed by a human hunter was not necessarily the last dodo alive. See http://en.wikipedia.org/wiki/Dodo#Extinction

Dodo birds are extinct.

the only known lsland that the dodo bird had inhabited was Mauritius.

The platypus is not listed as endangered. Platypus do not yet even qualify as threatened, although they are unofficially "vulnerable". Although very delicate creatures, sensitive to ecological changes, pollution and habitat loss, their distribution is still much the same as it was prior to European settlement, apart from in South Australia where they were wiped out last century (like many native species), being hunted for their fur. The platypus is now a completely protected species.

This is what killed the dodo bird there was a brown tree snake that was about over 2 meters long,and some type of flies.

When man found the island. They ate a lot of the birds. Which in the long run contribute to their extinction.

Because they were the first well-known bird in mauritius

1. The dodo (Raphus cucullatus) is an extinct flightless bird that was endemic to the island of Mauritius, east of Madagascar in the Indian Ocean. Its closest genetic relative was the also extinct Rodrigues solitaire, the two forming the subfamily Raphinae of the family of pigeons and doves.

Dodo birds no longer lay eggs, as they are an extinct species.

Dodos were endemic to the island of Mauritius in the Indian Ocean.

The color of the feathers of the dodo bird were gray.

yes, but since they couldn't fly it was on the ground

none

yup but they couldn't fly.....just like penguins!

The Dodo bird may have survived for 30 years longer than was earlier thought. The last confirmed sighting was in 1662, but it is now believed that the last Dodo died in 1690.

As it evolved in isolation it had no fear of predators and humans. Being a flightless bird it was easy prey for non-native species and humans. Also it is believed that their nesting grounds were destroyed as well.

the dodos bird lifespan was abot 30 yrs although it is not accurate of how long the species in general lived. - Kenia h.

Yes. The dodo, which lived on the island of Mauritius, is extinct.

This flightless bird which was related to pigeons and doves became extinct somewhere in the mid-to-late 17th century. Controversy surrounds the actual date the last dodo was sighted, due to conflicting accounts, but it was believed to have been sometime between 1662 and 1690

Scientists are looking at cloning the dodo from museum specimens, but it should be noted that this experiment has failed with numerous other extinct species ...

Dodos are real, they went extinct as the birds had no natural predators, so they were unafraid of humans and we overhunted them.

it was about a meter tall, weighing about 20 kilograms (44 lb)

well, when the dodo's used to thrive in the island of mauritius in the indian ocean the climate was a tropical as well as subtropical one that is why the dodo used to experience wet and dry seasons.climatical changes made it adapt to different situations of availability of food.It used to eat a lot of fruits and seeds which were its basic diet and used to grow fat at the end of the wet season so that it could not face any food scarcity at the time of the dry season.This is the reason why some sailors documented that dodos were greedy birds, and had a voracious appetite

No. Birds are not mammals. They do not nurse their young, and most have feathers, not hair and fur like mammals. There are flying mammals (bats) that do nurse their young.
The dodo bird (which is presently extinct) was not a mammal. By definition, birds are not mammals.
