USA Road Trip day 5

We spent a few hours at the Yellowstone Bear World. It's a bit like a safari park, where you drive around and the animals are loose around you. Everyone is warned not to open their windows. Of course as tough Kiwis we ignore these instructions to get better photos. Just as well the bears had been fed before we got there. 

Notice how these two birds have similar plumages?

I've always known that I was short, but this comparison gives me an inferiority complex...
