Actually, he'd have a very good reason to expand his territory. Wolves are gregarious. Since he was a lone wolf, there's a good chance he was looking to team up with others to establish a pack. They've collared wolves that have travelled 1000 miles looking for mates,etc. Food isn't the issue, finding other wolves on the island may pose a problem.
This raises an interesting question. If the animal is determined to be a wolf, is its presence here (on the island) purely an abberation or should we conclude that Labrador wolves are expanding their range southward? (I think there has been some evidence of that within Labrador itself, but its largely anecdotal). The severe decline in the caribou population in Labrador might be a factor here.
Some have said the coyote genes in NL contain wolf DNA. I question whether the DNA results from this one will be conclusive anyhow, but I'm not a geneticist.
All 'eastern coyotes' have wolf DNA in their lineage. But you're right, if its not a pure wolf, then the DNA results may not be entirely conclusive.
