Not quite the same sizewize as an eagle, but still impressive - A couple of weeks ago, during my morning run where the bike trail branches off from the road by the golf course with the forest close by on the left, I must have noticed a movement on the standing tree trunk. When I stopped, just a few feet in front of me was a pileated woodpecker with its wings spread diagonally across the trunk. Of course, before I could whip out my camera, it quickly worked its way to the other side of the tree and flew off in the under story of the woods using some appropriate woodpecker language. I later concluded that the reason for the spread wing pose was that I was standing in its escape route and it had to develop a Plan B.
The configuration from where I stopped was a past double tree with one stem near to me being a hollow stump. My first thoughts were that the bird might be nesting in the hollow stump, but examination showed that it had been digging for grubs or worms in the stump vicinity.
