Passing On: 100 years ago, the last passenger pigeon died

It was once the most abundant bird in North America, comprising 1/4 of all birds:

It appears that its peculiar communal mating and nesting behavior made it very easy to kill them en masse and that plus their utility lead to their demise.

The Long Now Foundation considers the Passenger Pigeon a (strong) candidate for de-extinction [1]. There is also a recent reflection on the passing of Martha from them at that link.

Even if cloned, these birds won't come back as a whole. The instinct and habits of the original passenger pigeons are gone. It's like cloning a mammoth from a elephant, only to see it live like an elephant.

Instincts and any other genetic behavior would come back. Only learned behavior would be gone, but it can be relearned.

The question is: is the DNA contained inside the stuffed pigeons enough (and of good enough quality) to clone the birds entirely or merge the DNA with rock pigeon DNA?
