The squirrels are about the size of our common grey squirrels, and very handsome. They are of a brown grey colour, beautifully speckled with small brown spots, and burrow in the ground. We killed several of them since we came to this camp.

The magpie is also plenty here, and woodpeckers of a different kind from any I had before seen. They are about the size of a common red-headed woodpecker; but are all black except the belly and neck, where the ends of the feathers are tipped with a deep red, but this tipping extends to so short a distance on the feathers, that at a distance the bird looks wholly black.
