Out on the Cary Pines Trail, bracken was a study of threes.
Approaching the Appendix, I noted an empty egg shell along the path. Maybe a robin's?
On the Wappinger Creek Trail, invasive narrow-leaved bittercress was flowering. Last call to compost this before seeds are too mature.
Farther along, after the foot bridge, a dead or dying tree was sprouting a fungus. I've watched this kind grow over an inch in radius per day.
As I climbed the bluff, a blur of a great blue heron streaked along the water below. Even at quite a distance and through the trees, if I could see it, it could see me. It left.
Several angelica were starting to bloom in the Sedge Meadow.
Near the enormous fallen white oak, a fresh northern eudeilinea rested on a leaf.
I don't know how many different galls I came across today. Secretions of a larval insect cause a plant to grow a shelter for it to live in. There's actually a field guide for them.
Out along the edge of the back Old Hayfield, a pair of song sparrows was very attentive to me. Their nest must have been near by.
