Fawn Season

 

After riding through the fog-drip that started just below Pantoll I had to pedal up past Rock Spring toward East Peak to finally reach the sunshine. Stonecrop and monkey flower were growing from crevices on this lichen-crusted boulder, and the gray-green oak in the foreground was in full flower.

Iconic summer weather, with fog still high on the mountain even in the late morning.

A couple of fawns hang out at the new trail camera location. It's too bad GardePro's information strip is overlayed on the image instead of placed below it.

I approached the new trail camera location prepared to find zero animal activations. They've only been up there a week, so even if it had been zero I'd have left them there another week. As it happened, the cams captured a few deer, a single gray fox, a couple of squirrels and steller's jays -- and a hiker. I don't know why I'm still surprised that hikers show up on off-trail cams. People roam all over Mt. Tamalpais. 

As I was about to ride back down into the fog at Rock Spring I saw this pale swallowtail butterfly (with still-pristine wings) fluttering around the chaparral pea and yerba santa flowers across the road. I kept hoping it would land and feed on the nectar of one of them, but it eventually sailed high into this oak to spread its wings and gather warmth.

A little later I saw it (or another one) fluttering around the chaparral pea again. It kept appearing to land but then it would flutter away before I could get a clean photo. It was only when I got home and viewed this image on a large screen that I noticed it appears to be ovi-positing on the pea's leaves. 

Riding back down toward Rock Spring I had just passed the Mountain Theater entrance when my bike spooked a pair of fawns that I hadn't even noticed, and then their mother. 

I was tempted to enter the woods to try to get a better view of them but realized it would be hopeless, even with the benefit of damp leaves that wouldn't crackle and crunch under my feet.

Fog still lingered over the meadow at Rock Spring when I arrived. I checked the area where I'd seen the hen turkey appearing to make a nest last week. The depression was still there, all the leaves and other detritus cleared down to bare dirt, but the turkey was long gone, there were no eggs, and a deer had unceremoniously deposited a generous ball of pellets at its edge. As I prepared to lock my bike to a tree before hiking to the trail cams, I realized the key to the lock had fallen off the keyring and was nowhere to be found. I left the bike unlocked and under the protection of the mountain gods and people's better natures.

There were many more yellow mariposa lilies in bloom this week, and insects were already taking advantage. I'm a little bit in awe of the fact that insects and flowers have their appointed times in each others' life cycles. The flower holds fast through its non-flowering season by bulb or seed, and I guess insects can be dormant as eggs (or the insects harvest from different sources throughout the year). But what about crab spiders, aka flower spiders, who can't fly? How do they spring into action and find their way to the mariposa lilies where their color gives them perfect camouflage?

The obvious answer to how they find their way seems to be that the females lay their eggs on or near the flowers, which are likely to grow again in the same place the following year. Apparently the spiders can alter their color somewhat when they molt, depending on the color of their host flower.

If you look closely at this photo (click to view larger) you'll see there's a carnivore also taking advantage of this mariposa lily. The skipper stopped by to sip sweet nectar, but was soon spooked away by a flower spider laying in wait.

I walked by this colorful patch of checker bloom once without taking a picture but succumbed to the temptation when I passed it again on my way back to my bike (which thankfully was still there). You can see some dogtail grass in there as well, and I noticed that a large patch of it that I'd photographed before in that general area has been overtaken by other grasses this year.

Kehoe Beach

 

Blue-Beaked Amigos

As I hiked around a bend toward Kehoe Beach this morning, spooking brush rabbits and sparrows back into the dewy jungle of mustard, radish, and poison hemlock that hugged the narrow trail, my eyes lit up when a small chocolate-brown bobcat executed a rapid, low scuttle away from me for maybe ten yards before ducking off the trail. It happened so fast that I couldn't get a shot despite the fact that I had already mounted my long lens to the tripod in anticipation of just such a lucky encounter.

I would get one more chance to photograph a bobcat as I was leaving for home. Although the cat ducked into the roadside vegetation when he saw me, I stopped my car, turned off the motor, and waited to see if he'd come back out. The park roads provide very few places to pull off the road to appreciate views or look for wildlife, but since it was still early Tuesday morning, I was able to just stop in the road with no other cars passing by. 

After a few minutes of keeping my eyes and ears open I heard a twig snap behind me. I looked over my shoulder but didn't immediately see that the cat had re-emerged onto the road, and by the time I finally saw it padding away I was only able to fire off two frames before he sped up and moved out of range.

My initial purpose for driving out to Kehoe was the hope of finding another group of juvenile peregrine falcons like the ones I photographed in 2018 (a year when I didn't blog). This time I saw only one juvenile, and with no boisterous siblings urging it on, it simply clung to a cliff ledge near its nest the whole time I was there, never coming down to the beach. 

Not only did I see no beach falcons during my walk, but the only birds I did see were a handful of widely scattered gulls. It was a bit of bum luck to go along with the foggy, drizzly morning until my spirits rose at the sharp whistle of a black oystercatcher. On my way back down the beach I was able to hang out with a few of them as they relaxed on a seaweed-draped rock.

A little farther down the beach I watched a great blue heron hunting at the water's edge, plucking little mole crabs out of their sandy, salty lair. The heron appeared to make a jab at a fish when it ventured into slightly deeper water at one point but came up empty.

In addition to the usual wildflower suspects such as yellow bush lupine, seaside daisy, lizard tail, paintbrush, and yarrow, I discovered a species I'd never really appreciated before, with its twirling inflorescence reminiscent of a Christmas tree, called silver beachweed. I've probably picked its burrs out of my socks without knowing where they'd come from.

June Boom

 

California Quail

The annual grasses are turning brown, but Mt. Tamalpais is booming with life. California quail are calling to each other and keeping watch, wild turkeys are nesting, bucks are sporting ever-larger (and still growing) antlers, new wildflowers are blooming, and dragonflies and fence lizards are soaking up the sun. In the woods, fog-drip has been keeping the forest floor moist enough for banana slugs, as well as everyone's favorite woodland plant, poison oak.

The fecundity of the woods kind of blew me away when I was relocating my trail cams and approached a pool I've set up on before. The thick undergrowth showed no sign of the usual animal trails in the vicinity, and I had to gingerly make my way to the pool through abundant poison oak. When I got to the pool I was disappointed to see that winter storms had filled it with gravel. With the pool gone, and the approach so full of poison oak, I decided to set up the cams elsewhere. 

When I returned to my bike near the Rock Spring parking lot I watched a tom turkey strutting his stuff in the shade of the beautiful oak near the trail-information board. While I was watching I heard a scuffling of leaves in the nearby woods and discovered a hen turkey scooping out a depression and lying down in it. It didn't look like dirt-bath behavior, so I look forward to checking up on her again to see if she was making a nest.

Guano meets the high tide line on this rock off Baker Beach at low tide. You can just make out the bright red color of an ochre sea star near the rock's base.

Thursday started out sunny in San Francisco, but clouds soon moved in from the north. 

The container ship Wan Hai 361, loaded with goods from Taiwan and China, enters San Francisco Bay.

I was surprised to see the broomrape had actually gotten smaller instead of bigger. This is the same cluster I photographed last week. The non-photosynthetic plant is probably getting its nourishment from the green yerba santa growing next to it.

This wild rose with hover fly was right next to some other broomrapes.
