While with a group from West Valley College Park Management Class 15B I came across some scat and looking for identification. Thanks
Jumping Spider (Phidippus adumbratus?)
Found out side of the rotary furnace at the head of yellow kid trail, unable to get measurements or gps. Looked about as long as my thumb is wide so around 2cm, but once more could not get an exact measurement. Very responsive and seemed turn away from any one that got close at first until it was surrounded at which point it began running in quick straight lines.
I don't expect anyone to confirm this sighting. I had just always wanted to get a picture of a hummingbird in a display flight, and then, as luck would have it, I got two such photos in dramatic twilight.
