Of course, sea anemones don't have faces. They do have mouths, though, and since a mouth is usually part of a face, you can sort of imagine what I'm getting at. The sunburst anemone, Anthopleura sola, is one of my favorite intertidal animals to photograph. Of the four species of Anthopleura that we have on our coast, A. sola is the most variable, which is why it keeps catching my eye.

This afternoon I met the members of the Cabrillo College Natural History Club for the low tide at Natural Bridges. Here are some of the A. sola anemones we saw.

Such an amazingly photogenic animal, isn't it?

This past Fall semester the NHC went tidepooling at Pigeon Point. Today we were at Natural Bridges, and later in the spring we are going to Asilomar. I didn't intend it, but this school year the club is getting a look at three very different intertidal sites.

I love it when things work out that way!

It's no secret that I love pelicans. I love watching them soar low over the waves, where they are truly in their element. I love watching them plunge from the air into the water and then bob right back to the surface, because unlike their cormorant relatives, pelicans can't fly underwater. And I love watching them plunk around on land, where they are dumpy and awkward but still somehow elegant.

The other day I ventured out between storms to photograph birds. As per usual I ended up down at Natural Bridges, where pelicans were hanging out on the last remaining rock arch. They were well within the reach of my long lens, so I took a lot of photos.

The best photos I got were of a subadult pelican coming in for a landing.

The youngster managed a safe landing without knocking one of its compadres into the water. That isn't always the case--those wings can do a lot of damage. But the three adult birds on the left hardly seemed to notice, which means the youngster has learned how to stick the landing without disturbing everyone else in the vicinity. I'm sure that's a lot easier said than done!

Autumn is migration season in California. We all know that, in the northern hemisphere, birds fly south for the winter and return north for the summer. And indeed, this is a very good time to go bird watching along the Pacific Flyway, as migrating birds stop to rest and feed at places such as Elkhorn Slough. Here in Santa Cruz, autumn is punctuated by the return of monarch butterflies (Danaus plexippus), roosting in eucalyptus trees at Natural Bridges State Beach and Lighthouse Field.

Since 1997 the Xerces Society for Invertebrate Conservation has been tracking monarch sightings on their migrations between the western U.S. and Mexico. They conduct a volunteer butterfly count every Thanksgiving. More recently, community science data sources such as iNaturalist provide much of the information.

Xerces Society Western Monarch Thanksgiving Count. 2019. Western Monarch Thanksgiving Count Data, 1997-2018. Available at www.westernmonarchcount.org.

This morning, before it got warm, I went to Natural Bridges to see how the monarchs were doing. I wanted to photograph clumps of butterflies dripping from tree branches. It seemed, however, that there aren't as many butterflies as I remember from previous years. The clusters were not nearly as large or as dense as they should be. And the data shown in the figure below do demonstrate a precipitous decline in monarch since 2017. We're still a couple of weeks away from this year's Thanksgiving count, and there is still a chance that the butterflies might arrive in larger numbers.

Xerces Society Western Monarch Thanksgiving Count. 2019. Western Monarch Thanksgiving Count Data, 1997-2018. Available at www.westernmonarchcount.org.

Trained observers know how to estimate the number of butterflies in a cluster like this. The numbers of butterflies at various roosting sites are aggregated to assess overall population sizes.

This morning I did see one butterfly that had a tagged wing. It was wearing a green Avery round sticker, with some writing in what looks like black Sharpie. The color of the sticker was very close to the green of the surrounding foliage, so I wasn't even able to see the sticker until I downloaded the pictures from the camera.

At first I thought the tag resulted from an official scientific project or undertaking, but it turns out that anyone can tag a monarch. The tags are used to track migration of the butterflies. There doesn't seem to be a central depository of tags and their origins, so knowing the color of the tag doesn't tell me where this particular butterfly came from.

Once the sun hits the butterflies and they begin to warm up, the clusters start breaking apart. Butterflies open and close their wings, exposing the darker dorsal surfaces to the sun and warming up their flight muscles. Sometimes they dislodge one another.

On a cool morning like this, many of the butterflies that fell out of the clump couldn't fly yet, and landed on the ground. The boardwalk is perhaps not the safest place for a butterfly to wind up, but at least in a monarch sanctuary such as Natural Bridges the visitors are knowledgeable and look out for the butterflies' safety.

As I wrote before, the butterflies we see at Natural Bridges this year were not born here. This means that their survival to this point has depended on healthy conditions in the Pacific Northwest and the western slopes of the Rocky Mountains, where they lived as caterpillars and emerged from their chrysalises. This also means that planting milkweed for monarch caterpillars in California won't help the butterflies that we see here, although it would help butterflies that are destined to overwinter elsewhere. What will help local butterflies--monarchs and otherwise, and all nectar-feeding insects, in fact--is planting California native plants, to provide them with the nutrition they have evolved to survive on.

People call them air rats or trash birds, but I really like gulls. Especially the western gull (Larus occidentalis), known colloquially among birders as the WEGU. Yes, gulls eat garbage, but that's only because humans are so good at making garbage and leaving it all over the place. Other gulls may travel quite far inland--in fact, the state bird of Utah is the California gull (Larus californicus)--but the WEGU is a California Current endemic species. This means that its natural food sources are the fishes and invertebrates of the California Current, which flows southwards along the west coast of North America. As a result, it lives in only a very narrow strip of coastline, nesting on cliffs and restaurant roofs.

Case in point. Yesterday afternoon I was at Moss Landing with my marine biology students. We had hiked along the road, over the dune to the beach, down the beach a ways, and returned over the dune to circle back to our starting point. The last item of note that we all watched was a western gull hunting along the shoreline of the Moss Landing harbor.

It had grabbed a crab. It looked like a rock crab, but I couldn't tell what species.

The crab wasn't dead, and was thrashing around enough to make it difficult for the gull to get a good grip on it.

I don't remember what I expected from my first view of Death Valley. I knew it to contain the lowest elevation (Badwater Basin, 282 feet below sea level) in North America and that it was really hot in the summer, but beyond that I had no clue. [Aside: the marine biologist in me wondered which metric 'sea level' refers to, and decided that it was probably mean low low water] I certainly wasn't prepared for the spectacular geology, although in retrospect I shouldn't have been so surprised. We didn't see much in the way of wildflowers, for one reason that I didn't anticipate but which makes perfect sense: although Death Valley received enough winter rain to form a temporary lake in the valley, there hadn't been enough rain in the autumn to trigger a superbloom. That was fine by me, as I'd already seen many wildflowers on the trip and was happy to be fascinated by the geology.

There are at least two small waterways in Death Valley National Park that are called Salt Creek. The first one we encountered was in the hills above the valley, and is a rare desert riparian area.

This Salt Creek is fed by several small natural springs and runoff from the scant winter rains. As you can imagine, this oasis is a vital necessity for wildlife. Animals as large as desert bighorn sheep and as small as quail depend on this water source, which may contain the only somewhat reliable drinking water for 15 square miles.

As I mentioned, for me, Death Valley ended up being all about geology. I knew the valley floor was where we would find the lowest elevation in North America: Badwater Basin, 282 feet (86 m) below sea level. And now I can say that I've seen it, but there isn't much to see except the line of other tourists hiking out across the salt flats to take photos of the sign. So as a must-see destination, Badwater was interesting but not compelling. We skipped it.

But the rocks! The hills surrounding the valley, especially those on the eastern side, are spectacular. My favorite area was a range of hills called Artists Palette, viewable from a gorgeous 1-way loop drive off of Highway 190. When I saw the name on the map I thought it must be a place either a location where painters found minerals they could use to make paint, or a scene they liked to paint. Fortunately we decided to take the detour that meanders through the formations, so we could get off the main road and just gawk. I had never seen anything like this scenery. I know enough geology to understand that minerals come in all sorts of colors, but had not seen them together like this in a natural state. My eye is always drawn to colors, and I couldn't stop goggling at the variety of umbers, ochres, greens, and pinks, all jumbled together like some giant's ice cream sundae.

It's impossible to capture the grandeur of this landscape in a photograph. You really have to see Artists Palette in person to appreciate the vibrant colors of these hills. If you ever go to Death Valley , take the time to drive this little loop. You won't regret it!

Across the valley to the west, are the Panamint mountains. Beyond them, the Owens Valley and the mighty Sierra Nevada!

So those are the rocks. The fish were in the second Salt Creek that we encountered, about 20 miles north of the Artists Drive loop. This Salt Creek is one of the remnant small bodies of water left after Lake Manly dries up. Lake Manly is a temporary lake that occasionally forms in Badwater Basin after unusual heavy rains. Most of the time, though, Badwater Basin is dry except for some small creeks. Salt Creek generally flows from north to south down the valley and eventually disappears into the sand.

Salt Creek is inhabited by a little pupfish, Cyprinidon salinus salinus, that looks like and is about the size of a guppy. Well, maybe it's a little bigger than a guppy. Populations of pupfish inhabit several creeks scattered over the desert across California and Nevada. Over time they have evolved into 10 genetically distinct species and subspecies, each adapted to the nuances of its particular stream. Two of the 10 have gone extinct in historic times. The Salt Creek pupfish, C. salinus salinus, is endangered, due to the ephemeral nature and fragility of its environment.

They are called 'pupfish' because they appear to be playing like puppies. Plus, they are very cute. But life as a fish in one of the driest places on the planet is a tough gig. Pupfish live short, intense lives, growing to adulthood and breeding in the span of a single year.

Salt Creek pupfish (Cyprinidon salinus salinus) in Death Valley


As you can see, the creek is hardly deep enough for these little fish to swim. Pupfish exhibit the sexual dimorphism common in fishes--females are rather drab and nondescript, while males are more colorful. The behavior that was described as playful, earning the fish the moniker 'pupfish', is really all about the business of living. Males are territorial, defending a spot against other males. When a female chooses to spawn with a male, she enters his territory. Then the two of them perform a short, wiggling dance, and spawn together.

From the perspective of an evolutionary biologist, the isolated pupfish populations are fascinating. Each waterway inhabited by pupfish is an independent 'island' in a very real sense of the word. The fish cannot migrate between streams, and thus populations evolve independently of each other. This is called allopatric speciation, from the Greek roots 'allo-' meaning 'other' and '-patry' meaning 'country'. Over time, each population becomes reproductively isolated from the others, so that even if Manly Lake were to become once again a permanent body of water, the fish from different streams would be unable to mate with each other.

Of all the things that manage to eke out a living in what is arguably one of the most inhospitable places in the world, these little fish are my favorite. Major props to them, for surviving where they do and making it look like fun!

Joshua Tree National Park gained a certain notoriety this past winter, when idiots went there during the federal government shutdown and trashed the place. The vandals chopped down the iconic Joshua trees (Yucca brevifolia), let their dogs run around unleashed, left litter scattered over the landscape, and carved new roads through the desert. I'd like to give most people the benefit of the doubt and assume that they didn't realize the damage they were doing to the park. However, it takes only a few bad apples to destroy a public resource for everybody, as we've all experienced at some point.

The very first thing I learned about Joshua Tree is that it has two distinct desert habitats. Hey, I'm a marine biologist, and the desert--any desert--is new territory for me. None of this landscape has been anywhere near the ocean for millions of years! Anyway, the eastern half of the park is Colorado Desert, which is similar to what we had seen at Anza-Borrego State Park. Many of the plants in this region were also familiar to us because we had seen them in Anza-Borrego, but for the most part were more abundant here in Joshua Tree.

For example, we saw many more bluebells (Phacelia campanularia) at Joshua Tree than in Anza-Borrego. The P. campanularia at Joshua Tree also looked healthier (more robust and vigorous, less spindly) than they did in Anza-Borrego. Perhaps the higher elevation of the Colorado Desert in Joshua Tree (approximately 914 meters, or 3000 feet) compared to Anza-Borrego (182 meters, or 597 feet) accounts for this observation.

I really liked the Colorado Desert in Joshua Tree. Even though it was the same ecosystem as what we saw in Anza-Borrego, here the flowers seemed more colorful and striking. The yellows were a little brighter, and the pinks and blues a little deeper. The scenery was breathtaking everywhere I looked. I wish my photos could do justice to the beauty of the landscape.

Aside from the desert bluebells, other flowers that we had seen at Anza-Borrego included the brittlebush (Encelia farinosa), which seems to be ubiquitous in the Colorado Desert. The Arizona lupine (Lupinus arizonicus) was also common in Joshua Tree; like the bluebells, these appeared to be more robust here than in Anza-Borrego.

There were new flowers, too. My favorite, which I didn't see a lot of, was this desert globemallow, Sphaeralcea ambigua:

Against the prevailing palette of yellows and purples, this orange really stood out and caught the eye. This plant is also called the apricot mallow, for obvious reasons.

Some other flowers that we saw:

Among all the colorful flowers in the overall landscape, there was this very subtle plant, easily overlooked by eyes accustomed to more brilliant blossoms.

Something that tickled my funny bone was the little chia plant, Salvia columbariae. It looks like a prickly purple pom-pom. Two days in the desert had taught me not to touch things if I didn't know what they were, but I had to know if these blossoms were as pokey as they looked. They weren't!

There are parasitic plants in the desert, too. The red branches in this bush are the desert mistletoe (Phoradendron californicum), a hemiparasite. It drains water and nutrients from its host plant but performs its own photosynthesis.

In Joshua Tree National Park there's an area called the Cholla Cactus Garden. Chollas are cactuses with cylindrical stems, rather than the flat stems of the beavertail or prickly pear cactuses. The most common one in the Colorado Desert (that we saw, at least) was the teddybear cholla, Cylindropuntia bigelovii. As the name implies, it's a cute, fluffy cactus, but it's definitely still a cactus.

The teddybear cactus blooms in May and June, so we didn't see any flowers. In addition to having the normal plant sex using flowers, these cactuses also reproduce clonally by dropping branches. The dropped pieces roll around and find a new place to attach and grow. Interestingly, this type of clonal replication, called budding, is common in many marine invertebrates!

The trees that give Joshua Tree National Park its name live in the higher and cooler western region of the park, known as the Mojave Desert. The Joshua trees (Yucca brevifolia) live singly or in clusters. In some ways, Y. brevifolia is the symbol of the Mojave Desert. They are also abundant in the higher elevations of the Tehachapi Mountains along Highway 58 between Bakersfield and the town of Mojave.

I'll have more to say about reproduction in Joshua trees and some other desert plants in another post. This one is getting long, and we had more desert adventures to come.

Next stop: Death Valley

The first new-to-me visit on our spring break road trip was Anza-Borrego State Park in the southern California desert. We arrived late in the day on Monday and had just a brief chance to look around. On Tuesday we got up early and went for a hike, trying to avoid some of the midday heat. Fortunately there was a bit of a breeze, which helped with the heat but made flower picture-taking challenging.

Anza-Borrego is located in the Colorado Desert, which is a western subdivision of the Sonoran Desert. The Colorado is a low-altitude desert (most of the surrounding hills are only ~900 meters tall) and thus gets much hotter in the summer than deserts at higher elevations, and very rarely experiences a winter frost. Winter is the main rainy season and some regions also receive rain during a late-summer monsoon season.

After a rainy winter, the desert explodes into vibrant life:

It had rained a few days prior to our visit, and there a stream was flowing through the desert.

This running water would be a temporary situation, of course, but one that is of great help to the wildlife in the park. At the park visitor center I read that wildlife large and small come to drink from the shallow streams, and that if we were to see bighorn sheep approaching the water we should stay out of their way. Water is so scarce for these animals that any delay in getting to it, or any separation of individuals from their family unit could be very stressful. I didn't know whether or not we'd even see the sheep, since they are shy, but we got lucky!

Handsome fellow, isn't he? He was eating and didn't seem to mind us hikers as long as we stayed on the trail. Of course, there was an idiot who approached too close to get a better photo, and this ram wasn't happy about it. He withdrew away from us and then went about his business. Other sheep wandered through, too, to forage or drink from the stream. But this big guy gave me the best photo op.

A visit to the desert this spring, after all the rain we had over the winter, was all about the wildflowers. Most of them were new to me. One thing that struck me was that, instead of the carpets of color that we'd seen at Carrizo Plain or Antelope Valley, flowers at Anzo-Borrega were much more widely dispersed. Some species were very common and others I didn't see more than once or twice.

As I mentioned above, yellow was the predominant color at Anza-Borrego. There were several daisy-like flowers in both yellow and white, and some were very common. Fortunately for me, the visitor center had an easy-to-use pictorial guide of the most common wildflowers; using that, some wildflower field guides that we brought with us, and Calflora.org, I may have identified them all correctly. I'm sure that somebody will point out any identifications that I got wrong.

One of the defining characteristics of E. farinosa is the way that the blossoms are raised up above the grayish-green foliage. It's a cool morphology, and makes the plant look very different when you see it from the side. Here's a shot that shows it:

Another very abundant yellow flower was the very aptly named desert dandelion, Malacothrix glabrata. It looks like a typical dandelion, perhaps a more pale buttery color than usual, and when mature the blossoms have a small purplish red spot in the center.

Our state flower, Eschscholzia californica, is typically a brilliant pure orange color, although sometimes the color can be more yellow. In Anza-Borrego I saw some plants whose foliage looked poppy-ish, but the blossoms didn't look quite right--a little too small to be California poppies and a color that was definitely yellow rather than orange. Turns out, though, that they were gold poppies (E. parishii)!

And who can resist a plant called ghostflower? That palest of yellows, almost but not quite white, combined with the tiny dark speckles, makes the plant seem very quiet--indeed, almost spooky. Ghostflower is easily overlooked, compared to the vibrant yellows of brittlebush, poppies, and dandelions.

One of my favorite flower color combinations is yellow, white, and purple. Imagine how pleased I was to find it in the desert!

The color purple was represented by two species of Phacelia, P. distans and P. campanularia. Phacelia distans was by far the most common in the floors of the valleys, and we saw P. campanularia at higher elevations.

This is Phacelia distans. Note the shape of the inflorescences, and how the blossoms are arranged.

And this is Phacelia campanularia, the desert bluebell:

These plants have the same blossom shape, but very different blossom arrangements and foliage morphology. Nifty, the differences between presumably closely related species, eh?

Another flower in the purple family was the desert sand verbena (Abronia villosa). It occurred in sandy soils, often in washes or dunes, similar to the sand verbena that I see on beaches along the coast.

The pink color family was represented by the bright pink Bigelow's monkeyflower, Diplacus bigelovii. They were fun. The golden-orange throat is the diagnostic feature for this species.

This being the desert, much of the plant biomass was succulent in nature. The ocotillo were blooming, as were the teddybear cholla and other cactuses.

Everything living in the desert survives only if it can take advantage of the minimal precipitation that falls every year. Cactuses must suck up as much water as they can during the wet season, and store it for use during the hot, dry summer. Barrel cactus (Ferocactus acanthodes) this spring are fat, like the barrels for which they are named, and full of water. Their bodies are pleated longitudinally, allowing them to swell up when water is available. Then, as their water stores are depleted during the summer, the pleats fold together and the body becomes more compact. The large saguaro cactuses in the Sonoran Desert do the same thing.

A cactus whose blossom definitely belongs in the pink category is the beavertail cactus (Opuntia basilaria). I think it was early in the blooming season for them, as I never saw any plants with more than a few open flowers, but most of them had many buds developing.

The chollas are cactuses in the genus Cylindropuntia, characterized by cylindrical stems. The teddybear cholla (C. bigelovii) was the one we saw at Anza-Borrego. It has dense spines that give it a fuzzy look but in reality form an impenetrable defense--it manages to say "I'm cute and fuzzy!" and "Don't touch me!" at the same time.

The teddybear chollas were very abundant at Anza-Borrego. We continued to see them as we continued on our trip. Next stop, Joshua Tree!

We've had a good strong wet season this year, resulting in another wildflower superbloom. Over spring break we went to southern California to chase the flowers and, while we were at it, visit some places that I'd never been to. Our first stops were at familiar stomping grounds that we'd visited in 2017: Shell Creek Road, Carrizo Plain, and Antelope Valley. There were significantly more people at all of these places, compared to two years ago. Many of the well known sites for wildflowers have become very popular lately, and we tried to avoid the most crowded areas.

Location 1: Shell Creek Road

Just because I love the California oaks, here's one that is well festooned with lace lichen (Ramalina menziesii) and moss:

The sky was hazy that day, making for less than ideal picture-taking conditions. The wind certainly didn't help, as the flowers were moving constantly. This early in the bloom the predominant color was yellow: a soft, buttery yellow due to the tidy tips and a much more brilliant, retina-searing gold due to the goldfields.

There was some relief from all the yellow, in patches of baby blue eyes.

Location 2: Carrizo Plain and Temblor Hills

Soda Lake Road, which runs through Carrizo Plain, was quite crowded. We stopped at the vista point and then headed off the beaten track onto some less-traveled dirt roads.

Still hazy, see?

There was such glorious scenery all around!

To the northeast of Carrizo Plain lie the Temblor Range hills, on which the bloom was just beginning. We saw fiddlenecks and goldfields at lower elevations, and splotches of purple Phacelia and orange poppies higher on the hills.

Poppies weren't going very strongly yet, but were distinguishable as a faint orange wash on the hills:

We'd see plenty of poppies the next day!

Location 3: Antelope Valley

Antelope Valley was overrun with people, climbing up hillsides with their dogs and selfie sticks. Seems that selfies of people sitting in poppy fields is all the rage these days. We didn't bother even trying to get into the poppy preserve, as there were lots of flowers to be seen in the surrounding areas.

Compared to what we saw at Antelope Valley in 2017, this year's bloom was different. This year the poppies were not as widely scattered as in 2017, but where they occurred they were extremely dense. Then again, this year we were early in the bloom, and by now it could be different.

Next up: Anza-Borrego!

Over the holiday weekend I was in Morro Bay for a surprise 80th birthday party--not mine! The party on Friday evening was a huge success (none of the guests let the cat out of the bag), the birthday girl was completely taken by surprise, and a good time was had by all. The weather was cold and sporadically stormy the entire weekend, but the clear spells between storm squalls were gorgeous and almost a little warm.

Since it wasn't raining on Saturday morning, we went out to Morro Rock to look for peregrine falcons. There are two (I think) pairs of falcons nesting on the Rock, one of which nests on the side of the rock that is visible to people. This is nesting season, and Morro Rock has a lot of ledges that make good nesting platforms. Peregrines don't make a nest, really. They lay eggs and incubate them on ledge high up on structures--rock cliffs, buildings, bridges--that dominate the landscape. We did see one peregrine way up on the rock, identifiable through binoculars but far enough away that I couldn't get a decent photo. This is the best I could do:

So not much success with the falcons, although I could at least document that they were there. Turning away from the Rock I was able to watch a great blue heron (Ardea herodias) go after and catch and eat a juvenile rockfish! The photos tell the story, so I'll just post them.

And there you have it! On a day when it was too blustery for human fishers to venture out of the bay, one avian predator had a successful morning. Way to go, bird!

Among photographers and those who watch the sky, last night's lunar eclipse was an event to stay up late for. In much of California the latest storm left the sky cloudy, but I was lucky to have pretty good viewing for most of the eclipse. The moon was behind clouds at the beginning of the eclipse and for most of the period of totality, though, so I didn't get any pictures of those times.

I did, however, take a series of photos of what I could see. Here they are, in chronological order. All photos were taken with my new camera, a Nikon D750 combined with the Nikkor 300mm f/4 prime lens.

At this point the clouds came back and it started to rain. I didn't wait for the eclipse to end, as I wouldn't have been able to see it anyway. When I got up this morning the skies had cleared, and since the moon would still be full I sat on the front porch in my pajamas and bathrobe and took this final shot.

And there you have it--my series of eclipse photos! I learned a lot while shooting and processing these. I am embarrassed at how long it took me to figure out how to create this montage:

Totally worth it, though!
