Photo from Jan. 16, 2011. This is a jackrabbit's form. Black-tailed jackrabbit. I surprised the animal off its form and it ran off. But, the form was very clear and had the appearance of having been well-used.
This is from last year. It's still stuck to the tree despite over 70 inches of rain this winter!
OK, so this is not an animal track. It is the "track" left behind by an acorn which was removed by a bird. Other things make tracks, and it's important to be able to differentiate them from animal tracks. So, I present to you an acorn track.....
Acorns opened by a bird using a stump as an anvil. Most likely a scrub jay in this area.
Termite galleries in an old log on the forest floor.
Swallows maintaining a nest under the eaves of a building.
New leaves just beginning to show on poison oak plant.
Sign of the Sonoma tree vole - discarded resin ducts from Douglas fir needles. These were from a fallen nest.
Sign of a Sonoma tree vole - scats and feeding/nest sign. These are the resin ducts from the Douglas fir, which these voles eat. They remove the ducts and eat the rest of the needle.
I took photos of this mushroom from November 2016, through January 2017 to document how it grew. See dates on photos. It never grew very large. The top split after a while. I am not sure what species this is.

Small mushroom stored in a tanoak tree by a Douglas squirrel.
Fungi stored on branches of the same tree by Douglas squirrel.
One of several mushrooms found stored in trees in a Douglas squirrel's territory on this day. This mushroom cap had fallen from the branch above, where the squirrel frequently perches to feed. See my other observations of this location for photos of the squirrel on this branch.
One of several mushrooms found stored in trees in a Douglas squirrel's territory on this day. This stem was stored on a log that was on the ground. A different sort of storage location, but near enough to the others to be the same squirrel. I have noticed that this squirrel does not retrieve and eat the stems as much as the mushroom caps.
