I was reading a romance novel - I think it was a Nora Roberts one, set in Alaska.
They had the heroine up in a plane, looking at a herd of moose. I howled. Moose are very solitary creatures. Calves stick with mom and twins might hang out together for a while their first year or two away from mom but otherwise, they are on their own. I figured out that she meant caribou, which would herd and would be much more prevalent than moose in Alaska, if there are even moose in Alaska at all.
