A wolf pack with two mothers?

All:

Now that the team is back up there, studying Ellesmere Island's wolves, the pack they're studying seems to have two nursing females. Which is rare in wolf packs, but has been known to happen, especially if the pack is large(and maybe about to split), but not unheard of. There is a "new" female who nurses at least some of the pups(they diddn't say how many there were). Then there's a "resident" female who apparently is the "alpha". Did she have some pups too, so they always have a milk bar when Mrs. Alphawolf is away? The team didn't say anything more, so all is mysterious at the moment. I look forward to hearing more. You can find it at this site. It also has some pretty neat pictures, one of which is of a wolf followng an ATV or the like. The wolf seems to be checkiing them out.
