This was so cool... I turned the bend and saw a jackrabbit coming down the path. Since we were on a 10-ft. wide levee, there were only two ways to go - either forward or back. After considering it for a moment, he came straight for me and passed only a couple feet from where I was standing. So fast! So cool!

It was really interesting to watch the jackrabbit interact with the two baby ground squirrels (at first I thought it was a baby jackrabbit). The jackrabbit hopped around them, then stopped to sniff them, and then went on its way. The baby squirrels weren't in the least bit scared of it.

I didn't see this bird. The Merlin app suggested this ID. There's a CA Scrub-Jay on this recording as well.

E. cicutarium, botrys and brachycarpum are all present on this section of the trail, offering ample comparison. (E. moschatum is far away, one day I'll get all 4 together!). E. cicutarium at top, E. brachycarpum at right, and E. botrys at bottom.

I took this opportunity to study these 3 species, most importantly botrys and brachycarpum, the differences of which are poorly documented. I observed 160 E. brachycarpum, and 242 E. botrys.

This observation is for the Hermit Thrush in the foreground. This recording was taken near the lake where there's a lot of bird activity.

Other birds: There is a Say's Phoebe call in the distance at about 15 secs, and a California Thrasher call starts at about 1:07. Also, some Acorn Woodpeckers.

Once the light is fading, Baby Owl takes their turn looking out of the box for a while, really getting their groove on (I know, it's a vision thing, but still funky). This night, this baby flew out, and a second baby looked out!

Here's some Baby Owl groove:

And a longer video of the two babies, lots of flapping, and a lizard delivery:

Finally, I created a Flickr album with a larger collection of photos and videos here: https://flic.kr/s/aHsmVZPnT5

A flock of wild turkeys. Notice the coyote walking past the flock. They aren't even alarmed! I wonder if they can sense the coyote's not hungry for turkey right now? Their heads turned in unison to watch the coyote pass. Very interesting!

Some rather scruffy-looking Common Mallow (Malva neglecta), photographed in a patch of mulch at Varian Park in Cupertino, CA. Note that there are two photographs in the set of poctures documenting this specimen - the lead shot (Shot 1.1), which provides a view of the plant in situ; and the remaining shot (Shot 1.2), which provides a closeup of one of the flowers and some surrounding leaves.

In identifying this plant, I made the following observations:

1) This specimen has bisexual flowers consisting of 5 sepals; 5 petals, a single pistil, and numerous stamens. The 5 petals are partially fused together to fom a corolla tube that is radial in its symmetry. The pistil has a superior ovary at one end 5 linear stigmas at the other. Finally, the stamens' filaments have fused together around the pistil, almost enclosing it completely. Together, all of these traits place this specimen firmly within the Mallow Family (Malvaceae).

2) This specimen is also an annual forb with axillary flowers, with up to 10 flowers per leaf axil. Inside each flower, one can see the anthers arranged in a single series near the top of the filament tube, just below the linear stigmas. Outside the flower, subtending the calyx, are three tiny bractlets that are generally free from each other (verified in the field, difficult to see in the photos). The stems of the plant are prostrate to erect. Together, all of these traits place this specimen firmly within the genus Malva.

3) Finally, for this specimen, sepals are about 4mm long, while the petals are around 8mm long (= 2x length of the sepals). The petals are white to pale lialc pink, with veins that are not darker than the base color of the petals. Together, these traits identify this specimen as Common Mallow (Malva neglecta), a non-native plant originally from Eurasia that has become more or less naturalized in northern California. It is also known as Dwarf Mallow.
