In my email today, I got a follow up message from a gal named Lauren de Boer. She had written to me in March:
“I am currently taking the citizen naturalist certification course and decided to focus on oaks. I’ve run across you name many times in the course of my research. You are prolific! And the quality of your photography is impressive. There is one photo where you are holding two live oak leaves for comparison that would be very helpful for the pocket guide to oaks I am creating. Would it be possible to have permission to use the photo? Since the guide will be for print and online, I would need a hi res version.”
I gave her permission to use the photo -- and whatever other photos she’d like to use -- and today she says:
“Thank you again for the use of the photo of oak leaves. The Pocket Guide to Northern California Oaks is finished and has been printed. Now I’d like to send you copy in gratitude for your contribution.”
Cool! I’m looking forward to seeing it and I’m so happy that I was able to assist an other naturalist with their capstone project.
We have a pair of Eurasian Collared Doves (Streptopelia decaocto) building a late-season nest in the palm tree in the backyard. The male was bringing the female twigs for the construction. #CABiodiversityDay.
According to Cornell: “…Building usually done by female with male gathering material. Male gives excitement calls while bringing female nest material; on arrival pair give nest calls and billing occurs… Male may push nesting materials directly under female. Build nest during daylight hours; usually takes 1–3 days…Incubation by both parents, with female sitting on nest through night and male relieving female in early morning for about 8 hours. Incubating bird usually summons mate for relief; male gives advertising call, female gives nest call…In warmer regions, Eurasian Collared-Doves can nest year-round, which may help explain their success as colonizers…”
“…Eurasian Collared-Doves made their way to North America via the Bahamas, where several birds escaped from a pet shop during a mid-1970s burglary; the shop owner then released the rest of the flock of approximately 50 doves. Others were set free on the island of Guadeloupe when a volcano threatened eruption. From these two sites the birds likely spread to Florida, and now occur over most of North America…Eurasian Collared-Doves are one of very few species that can drink “head down,” submerging their bills and sucking water as though drinking through a straw. Most birds must scoop water and tip the head back to let it run down into the throat…”
Here are some photos of the birds. In some of them, you can see the male bringing a twig to the female: https://www.flickr.com/photos/mkhnaturalist/albums/72157719787831123.
I got up around 6:00 o’clock and headed over to the Gristmill Recreation Area to see if I could find galls there. It was 61º when I got there but got up to 102º by the afternoon. PM2.5 AQI levels reached: 184 AQI (Unhealthy) .
There are a variety of oak tree there including Interior Live Oaks, Valley Oaks, some Black Oaks and Holm Oaks. I was shocked, therefore, when I found only a handful of galls. The Holm and Black Oaks gave me nothing, but it’s always fun to see them.
On the live oaks I found Erineum mite galls, Pumpkin galls, some fold galls and Live Oak Bud galls… but that was only on two trees. I didn’t find anything at all on the other live oaks I looked at.
On the Valley Oaks, I was expecting to see Red Cone galls everywhere but I only found them on ONE tree, along with a single Yellow Wig Gall, some Jumping galls, a handful of Spined Turban galls, small Flat-Topped Honeydew galls, and stem galls. And, of course, there were Oak Apple galls on a lot of the trees.
I got a few photos of a Jumping Spider (Colonus hesperus) on one of the leaves, and it was eating its breakfast. I had to chase it from one side of the leaf to the other until it finally stopped to stare me down.

I could hear a few birds like Nuttall’s Woodpeckers, Killdeer, Belted Kingfishers, and Oak Titmice, but I couldn’t get photos of them. I saw your basic Wild Turkeys, Common Mergansers, Mallards, Canada Geese, Wood Ducks, a Great Blue Heron, Mourning Doves, Black Phoebes and some Cedar Waxwings. There was also a small flock of Bushtits, but trying to get photos of any of them is always a challenge for me. They’re small and they move so fast!
I came across a birding ground that was following a “Warbling Vireo” in the treetops. I couldn’t see it, but it was fun to know that it was out there.
Not a lot happening, and I was only out for about 90 minutes because it was heating up fast, but I enjoyed the exercise. #CABiodiversityDay. This was hike #76 in my annual hike challenge.

I got up at 6:00 this morning, and headed out with my friend Roxanne for Johnson-Springview Park in Rocklin a little before 6:30. This was round two of our gall hunt there.
The last time we were there, we stuck mainly to the Blue Oaks in the front of the park. Today we went looking for the Valley Oaks and the Interior Live Oaks to see if we could find different galls on them. That’s not to say we didn’t shop at the Blue Oaks we came across, but we tried to keep moving to see the other oaks and plants in the middle section of the park. All the while we were out there, we had to keep an eye out for the disc golf players who were out in the park.
Although we found a variety of different species of wasp galls, it was very apparent to both of us that we weren’t seeing the number of galls that we normally see. Fewer galls means fewer wasps, or wasps that aren’t laying as many eggs as they normally do. And we still haven’t found ANY of the spiky-ball summer galls of the Live Oak Gall Wasp. That’s worrisome. We might be seeing the beginning of the end of some of these species.
On the Blue Oaks we found Clustered Galls, two different generation galls of the Striped Volcano Gall Wasp, pale yellow and bright pink galls of the Crystalline Gall Wasp, Gray Midrib galls, Saucer galls, Plate galls, Dried Peach galls, Coral galls, a couple of Disc Galls, and some Urchin galls. The most Urchins we found were on a tiny tree that had a wide variety of different galls on it. Some were pink, pink with white tips, or varying shades of purple.
On the Interior Live Oaks we found some old springtime galls of the Live Oak Gall Wasp, a single older Kernel gall, and a few Pumpkin galls. A nice surprise was being able to find some old spring galls of the Two-Horned Gall Wasp. We didn’t see any of the summer galls of that species, though… and I’m wondering if the extreme heat we’ve had this year burned out some of the summer generations of some of the species, or if we’ll see the summer generation galls later in the year when (potentially) it cools off a little bit before the Fall. There’s just so much we don’t know.
Later in the day, at lunch, Roxanne found this great 69-page article on keying out and identifying the galls wasp species: https://academic.oup.com/isd/article-pdf/4/4/1/33449191/ixaa003.pdf
“…While much has been learned regarding the phylogeny and evolution of cynipoid wasps, clearly illustrated diagnostic tools and identification keys have remained stagnant. So too, where keys do exist, they are often to genus or species, and there are no user-friendly keys to groups such as tribes, subfamilies, or families. This state of affairs leaves a knowledge gap for non-specialists and slows future research on the group. To address this, we provide a fully illustrated key to the higher-level groups of world Cynipoidea. We also provide summaries of all higher-level taxa with updated generic lists, biological data, distribution, and literature resources. The dichotomous key presented here is complimented with a multi-entry matrix-based key, created in Lucid, and served on www.waspweb.org with online versions of the dichotomous keys also available…”
Always learning more about these creatures.
On the Valley Oaks we found the Oak Apples, Red Cone galls, Convoluted galls, Spiney Turban galls, Yellow Wig galls, what we think might have been an old Rosette gall, and a single gall of the Live Oak Gall Wasp and the Fuzzy Gall Wasp, Burnettweldia washingtonensis. We saw what we thought might have been an example of the mid-twig gall of the Split Twig Gall Wasp, Dryocosmus asymmetricus… but then, that only forms on Canyon Live Oak, and we found it on a Valley Oak, so more research is needed. On one tree, we found honeybees lapping up the honeydew from the galls of the Flat-Topped Honeydew Gall Wasp. We also found examples of acorn affected by Drippy Nut, cause by the bacterium Lonsdalea quercina populi.
Here are the photos from today: https://www.flickr.com/photos/mkhnaturalist/albums/72157719778629566
On another tree, we found the old cocoon of a tussock moth with eggs on it.
“…The tiny, whitish eggs occur in a mass of several hundred, covered with the female's brownish hairs… Pupae occur on or near the host plant… Tussock moths overwinter as eggs. The tiny, dark caterpillars hatch in spring and can use a silk strand and their body hairs to float on the wind to other trees. After feeding, mature larvae pupate on bark in a hairy, brown or tan cocoon. The emerging females produce pheromone to attract the night-flying males; females of some species are flightless. Adults occur from late spring through at least early summer. There are one or two generations per year, depending on the species and location…”
On some of the cattails in the creek, we also found a few examples of “fasciation”.
“…Fasciation, also known as cresting, is a relatively rare condition of abnormal growth in vascular plants in which the growing tip which normally is concentrated around a single point and produces approximately cylindrical tissue, instead becomes elongated perpendicularly to the direction of growth, thus producing flattened, ribbon-like, crested (or “cristate”), or elaborately contorted, tissue…”
In the cattails, some of the head were split into threes, with three heads growing from a single stem. Very interesting!
So there was lots to see. We didn’t see many birds, however, but I still got some photos of a Black Phoebe, and some of the Yellow-Billed Magpies in the park. Many of the magpies were going through a molt, so they were looking a bit ragged.
There were also a few Western Fence Lizards darting about, including some pairs and a few tiny baby lizards.
We walked for a little over 3 hours and then headed back toward Sacramento. This was walk #75 of my annual hike challenge. We were happy to have had a fun outing and good weather.

I was supposed to go my GP doctor’s office today, but since she cancelled the appointment and rescheduled it for next week, I decided to go out to the Cosumnes River Preserve for a walk. So, I got up around 6:00 am and was on the road by 6:30. It was windy and 55º outside; just lovely.
There is no water at the preserve itself, and the trees along the now-empty pond by the boardwalk parking lot weren’t giving me a lot to look at. In fact, I was shocked to see that the gate there was still locked, so I had to park on the street. I was primarily looking for galls, and the trees along the pond had lots of Red Cones and a few others, but not a lot of variety.
So, I drove around instead to the line of trees along Desmond Road and checked them out. I was surprised to see water in the ditches along the road (which prevented me from getting to some of the trees; I didn’t have my rain boots with me.) Most of the trees there are willows and Valley Oak with some Cottonwoods thrown in. I was focused on the oaks for galls.
Because I was limited to Valley Oaks for oak trees in this location, I saw a lot of the same galls on different trees. Some had lots of galls, others, not so much. I saw a “healthy” number of Red Cone galls, which we hadn’t been seeing in other areas, and there were lots of Flat-Topped Honeydew galls attended by their cadres of ants. Other galls found included Club galls, Convoluted galls, Disc galls, Jumping galls, the big Oak Apples, Spiny Turban galls, Yellow Wigs, Fuzzy Round galls, and even some Woollybears. Nothing new, but lots to see and most of the galls were mature and nice-looking.
Here are my photos from today: https://www.flickr.com/photos/mkhnaturalist/albums/72157719776060797
Some of the leaves were covered with the white fluff associated with Woolly Oak Aphids. On one leaf, I found a small collection of the aphids in various instars. Here’s a video snippet of them: https://youtu.be/yRh77pY7IlM.
As I was checking out the trees, I walked face-first into a couple of very large orb webs and disturbed the Western Spotted Orbweaver Spiders that constructed them. D’oh! I also came across two different kinds of praying mantises: a Mediterranean mantis with a white pin stripe down its back, and an Arizona Mantis with her beautiful blue lips.
In that same area, I saw a Red-Shouldered Hawk sitting in one of the trees. Based on its dark, rich color I assumed it was a male, but it was molting and was kind of scruffy looking. I got some photos of it, and a video snippet of it calling to its family. Here’s a video snippet: https://youtu.be/MC52idQJAak

I got up around 6:00 this morning. After feeding the dog and letting him go potty, I headed out to the Johnson-Springview Park with my friend Roxanne to go gall hunting. It was about 68º when we got there, and the air was smoky. It also seemed a bit humid. I was really looking forward to finding galls on the trees there; it’s usually a treasure house of them because there are so many oaks and so many different species.
We were able to check out a series of blue oaks in the front of the park, and found lots of different galls including Saucer galls, Red Striped Volcano galls, Clustered galls, Crystalline galls, Peach galls, Plate galls, Gray Midribs, Coral galls, Disc galls, Hair Stalk galls, and a very few, very small Urchin galls. The Crystalline galls were all clustered against one another, completely covering many of the leaves on which we saw them. They were losing most of their color by now, but still very recognizable. And I was super happy to see the Coral galls; I’ve only ever found them at this park.
That was an auspicious start to our day, but after about 90 minutes, I started to feel really sick: dizzy, nauseated, sweaty. I sat down on a rock and Roxanne brought the car around as close to me as she could. I thought if I sat for a bit and had some water in the air-conditioned car I’d feel better. But then I felt like I had to vomit, so I got out of the car in search of a restroom facility. We were next to a brown building that I thought might house a restroom, but no such luck. I upchucked a bit on the outside wall (and that will probably show up on their security cameras if they have them; D’oh!) Then I saw the restrooms on the other side of a lawn so I headed toward them. Thankfully, when I got there, the first door I tried was open and I was able to settle in on one of the commodes. Stuff came out of both ends -- which is always fun, not -- and once that hideousness was over I felt a lot better. I don’t know what my body’s issue was. A combination of meds, breakfast, smoke and humidity I’m assuming. But, yuck, that is NOT how I wanted to spend the morning.
When I came out of the restroom, Rox was there to help usher me back to the car. I was kind of determined not to give up, so we rolled the car over next to some sycamore trees by the parking area. I was hoping we’d see some lace bugs, but nope. Instead we found an odd, stringy-looking fungus on the back of one of the leaves.
Then we rolled the car over to another spot in the parking area next to a small patch of oaks. There were some Blue Oaks, a Live Oak, and a Valley Oak tree in that one little area. Didn’t see much of anything on the Live Oak, but on the Valley Oak we found a few Red Cone galls and Spiney Turban galls.
Here are the photos from today: https://www.flickr.com/photos/mkhnaturalist/albums/72157719805764335
The big find, for me, was a “lifer” for us, a gall we’d never seen before: the fuzzy convolutions left by the Erineum mites (Aceria trichophila). We’d seen something similar to these on Live Oak tree leaves in our area, but the ones on the Live Oaks (Eriophyes mackiei) leave a kind of rusty residue on the back of the leaf where the mites have been feeding. Here, on the Blue Oaks, the mites create a concave “nest” for themselves, dressed in white hairs, on the back of the leaves, which then leave a convex lumpy mound on the top of the leaf. We only found them on one tree but there seemed to be a lot of them, affecting groups of leaves. What was cool about these -- besides the fact that we’d never seen them before -- was that I had just been reading about them the night before in Russo’s book (page 106).
By then it was 10-ish and already getting warm enough outside that sweat was running down the back of my neck, ick. So, we decided to call it a day. We’ll come back in a week or so, weather permitting, and check out more of the trees in the back of the park.
We walked for about 2 hours. This was hike #73 in my annual hike challenge.
Rox and I decided to try out the Granite Rock Grille for breakfast, and I was actually surprised by how hungry I was after being sick earlier. I had a Santa Fe Scramble with country potatoes, salsa and iced tea. The service there is a little slow, but the food is always very good.
I got up around 6:00 this morning, and it was a glorious 55° outside. I love the cool air! I got Esteban fed and pottied and was out the door by 6:30 to head over to William Land Park for a walk. I was hoping to find some praying mantises in the gardens, but… I didn’t see a one. It still bothers me how few insects I’m seeing…
I did, however, find a nice collection of Sycamore Lace Bugs on various leaves of a California Sycamore tree; adults and nymphs in various instars.
"...Sycamore lace bug gets its name from the lacy pattern seen on the adult’s wings, head, and thorax (chest region). Adult lace bugs are about 1/8 inch (3mm) in length. The wingless nymphs are smaller, oval and are dark colored. Adults and nymphs occur together in groups or clusters on the underside of leaves. The bug’s life cycle consists of seven different stages of development: an egg stage, five nymph stages and an adult stage, and can have several generations in a year. It can overwinter as eggs in leaves or as adults in protected locations such as under bark and fallen leaves and other debris near host plants..."
In the WPA Rock Garden the Sea Squill were in bloom all over the place; tall white pillars of flowers. They’re so pretty. When the flowers fade, they leave behind stalks of mitered seed pods.
In the middle pond, there are still waaaaay too many Sacred Lotus plants, leaving the ducks and geese only a tiny area of water in which to congregate. I could see some minnows in the water, but none of the crayfish that usually occupy the pond. At least there were bees around the lotus flowers…That made me feel a little better.
In one spot, there was a White-Breasted Nuthatch, a Black Phoebe, and some goldfinches all within viewing distance, along with a Yellow Warbler (a “lifer” for me; I’ve never seen one in the wild before). The warbler flew out into the lotus plants on the water after bugs and was assaulted by an Anna’s Hummingbird.
I was looking for information about the warblers through the Cornell site, and was surprised that a lot of the sections said, “Little information” or “No information”. So apparently, although the bird can be found across the US, it hasn’t been studied very closely by anyone. Amazing.
“…Captures insects by gleaning (picking food from a surface while perched), sallying (flying out after airborne prey) or hovering (picking food from a surface while in flight)… Primarily monogamous, but occasional polygynous matings… Yellow Warbler abundantly recorded host of Brown-headed Cowbird; a consequence, in part, of the warbler's own abundance and broad sympatry with Brown-headed Cowbird…”
I could also see adult and immature Western Bluebirds, some of them drinking sprinkler water from the seat of the stone benches. The adults looked like they were going through a major molt. In fact, a LOT of the birds I saw were at some level in their molts. Everyone’s getting ready for winter. Even the crows were scruffy looking.
Here are my photos from today: https://www.flickr.com/photos/mkhnaturalist/albums/72157719758048222
I saw a lot of squirrels, all being… squirrelly. There was one that was eating greens on the lawn, and another one that was scrambling about like madman. I think he was sexually frustrated or something because he kept bouncing off the trees and jumped a piece of wood. Hah!

At the large pond, the landscape maintenance crews are letting some of the plants grow wild. There’s now a huge bed of mint plants in one area, and the pokeweed plants are now towering overhead, about 7 feet tall with thick trunks. I’ve never seen them that big anywhere before so it was kind of a shock. They’re pretty plants but very poisonous.
“…Pokeweed is poisonous to humans, dogs, and livestock. In early spring, shoots and leaves (not the root) are edible with proper cooking, but they later become deadly, and the berries are also poisonous… It has simple leaves on green to red or purplish stems and a large white taproot. The flowers are green to white, followed by berries which ripen through red to purple to almost black which are a food source for songbirds such as gray catbird, northern mockingbird, northern cardinal, and brown thrasher, as well as other birds and some small animals (i.e., to species that are unaffected by its mammalian toxins).. The seeds have long viability, able to germinate after many years in the soil...”
I saw a lot of Western Bluebirds flying into and out of the plants stealing the ripe berries, but they moved too fast for me to get photo of them.
Along the edge of the large pond, I also saw a Double-Crested Cormorant, sans crests, drying itself off after a swim, looking for fish in the water. The birds don’t have the water-proofing on their feathers like ducks and geese do, so their feathers can get water logged. Then the cormorants move to a safe spot and stand with their backs to the sun and their wings held up in the “heraldic” position to dry them. This particular cormorant must have been relatively used to humans because it picked a spot where it was approachable, and it didn’t startle or jump back in the water when I walked around it to get a few more photos.
I was also happy to see a group of Muscovy Ducks grooming themselves in the grass. The Muscovy Ducks have knobby, gnarled red modeling on the heads and faces which I think is so interesting looking. And I like their heavy yellowish legs and feet; it looks like they’re wearing big duck-foot-shaped rubber boots. They’re the only domesticated duck that isn’t genetically related to the Mallards (like the Swedish Blues, Pekins, and Indian Runners).
I walked for about 3 hours and by then it was 71° outside. This was hike #72 in my annual hike challenge.
I got up around 6:00 this morning so I could go out to the William Pond Park by 6:30 am. I wanted to go checkout the Reverend Mother tree again before it got too sunny and hot outside. I was going to go out with my friend Roxanne, but she had family stuff to tend to, so I went out by myself. It was so smokey outside it was tough to stay out and walk in it. The sun was “red”, and its reflection on the river looked like flaming blood. Creepy! Current PM2.5 AQI levels in the area have reached: 170 AQI (Unhealthy). Because of the smoke cover, the temperature never got above 88° today, and there was a bit of a breeze. The breeze brought more smoke in, but at least the air was moving.
Because of the smoke, the Sacramento Zoo has been closing its doors early; and because of the proximity of wildfires, the Sacramento National Wildlife Refuge has closed its auto tour route so it can be used by fire fighters for staging their equipment.
At the park, I was pretty much just looking for galls today, so didn’t pay attention to much of anything else. On the Valley Oak trees nearest the parking lot, I found lots and lots of Red Cone galls, Oak Apples, and Spiney Turbans. I also found quite a few Round galls (with their lumpy bumpy surface) on those trees; my first sighting of the season.
The Reverend Mother tree still doesn’t have all the galls she normally has, but I was able to find more Red Cones and Spiney Turbans, along with Fuzzy galls, Convoluted galls, and Yellow Wig galls. I haven’t seen any Club galls, Rosette galls or Disc galls on her yet… There were, however, LOTS of Flat-Topped Honeydew Galls exuding their honeydew. I didn’t see a lot of ants tending to them, but I did see a lot of wasps.
In fact, there seemed to be wasps everywhere. I found them on the lawns, drinking water from the grass (the sprinklers had been on just before I got there), and around the trash cans and remains of what I think was a fish on the ground. It was so deteriorated that it had gone black so it was hard to identify what part of the fish it might have been. In another spot, I found a pair of wasps struggling with a dried leaf; they almost looked like they were in a tug-o-war over it. I wondered if they were masticating it to make wet papery mulch for a nest somewhere nearby. I couldn’t get near enough with my camera to be sure. Here’s a video snippet: https://youtu.be/K0QLZPS5LtI
On the live oaks I still haven’t found any of spiney ball galls of the Live Oak Gall Wasp, Summer Generation. They seem really late to me. I found a few Pumpkin galls and some Two-Horned galls, but the stand-out on the live oaks was the number of acorns affected by Drippy Nut, Brenneria quercina, Lonsdalea quercina, a bacterium that infects wounds in oak tissue/acorns. Lots of dark acorns, lots of “foaming” ones, and one that looked like it hadn’t been fertilized yet, so it was just a “female flower”; nothing was left attached to the cap buy a thin, white, skeletal-looking wick. So weird.

The water in the river is still really low right now; you can walk across it in places. At one spot near the river bank, I saw a Red-Shouldered Hawk in a tree, a Black Phoebe and some Spotted Sandpipers on the rocks, some Mallards in the water, and a Turkey Vulture on the opposite bank. They all pretty much ignored each other. A trio of Belted Kingfishers flew over a couple of times, chattering to one another, but they didn’t land anywhere near me so… no photos of them. I DID see the hawk later on in another tree being beaten up by some Northern Mockingbirds who wanted him to move along.
I also found an Assassin Bug nymph on some of the rushes by the water, and on a Coyote Brush bush, I found some more Lace Bugs. Some of the lace bugs were tannish-brown while others were pure white. I don’t know if that meant they were different species, or simply different instars of the same species. On the underside of some of the leaves, I think I saw the eggs covered in “varnish”.
“… Lace bug eggs are found on the lower leaf surface, usually alongside or inserted into a leaf vein. Adult females secrete a varnish-like substance over the eggs that hardens into a scab-like protective covering…”
I just think they are sooooo interesting.
I walked for about 3 hours and then headed home. This was hike #70 in my annual hike challenge.
SPECIES LIST:
Friday the 13th! I got up around 6:00 this morning, and decided to go out to Effie Yeaw Nature Preserve for a walk. There was still a bit of smoke in the air, but there were also high clouds so it made things a little humid, too. It was 62° when I got to the river, and it was around 73° when I left.
Before I even got into the parking lot I saw a young female coyote loping through the grass. She took a winding route through the field and toward the car, then saw me, and did around-about through the trees, and finished off on the road. Because she was moving so quickly, it was hard to keep up with her with my camera, so I got some blurry shots of her as she went by.
Later, when I was walking the trail, I could hear a pack of coyotes yip-yowling from across the river. Cool.
When I walked around the nature center to head out for the trails, I came across two live oak trees that were oozing alcoholic flux. Both of the trees had been drilled up by sap suckers, and the sap wells allowed the bacteria to get in under the bark.
Alcoholic Flux bacteria [also known as Foamy Canker, Slime Flux], Phytophthora sp. x other bacteria “…is a stress-related disease that affects sweet gum, oak, elm and willow trees. The disease is caused by a microorganism that ferments the sap that seeps or bleeds from cracks and wounds in the bark. The result is a white, frothy ooze that has a fermenting odor similar to beer.”
The beer smell was obvious around these trees. Usually, you’ll also see insects around the flux, drinking in the ooze, but I only saw a few ants starting to move in. Sometimes, the insects (and other critters like squirrels] that feast on the flux exudate get drunk on it, and stumble around afterwards.
“…The] foamy, flux shouldn’t be something that causes you too much concern. It’s often thought of as benign, as it doesn’t damage the heartwood of your tree, and can often dry up when fall weather becomes cool and dry. And in any case, chemical treatments are typically ineffective…”
I was hoping to see some fawns out and about, but didn’t see any. There were a lot of bucks out, though, all of them still in their velvet.
As I was leaving the preserve, I saw three of the deer walking by me and through a small crowd of visitors, heading for the gardens in front of the building. They stopped to eat soft leaves off the redbud trees and some of the flowering plants like the yarrow, goldenrod and coyote mint. Smart babies.
I was also on the lookout for galls. On the live oak trees, I haven’t seen any of the spikey summer generation galls of the Live Oak Gall Wasp yet, and I didn’t see any today either. I did find the first Kernel Galls of the season, though, so that was nice.

I was happy to see galls forming on the “Frankenstein Tree” (half blue oak, half valley oak) for the first time in years. I’m not certain, but I suspect that Round-Up had been used around the base of the tree to control weeds… and thus poisoned the ground and the tree, making the tree unpalatable to the gall-forming wasps.
On this trip, I found Plate galls, Striped Volcano galls, Clustered galls, and Saucer galls on the tree. So great to see. The tree persevered! On the other go-to Blue Oak, there were Crystalline galls and Hair Stalk galls among others.
The Valley Oaks were just starting to show off large caches of Red Cone galls.
There aren’t a whole lot of bird species out this time of year, but I did see (and hear) a few. There were Red-Tailed Hawks screeling at one another. I figured they were up in a pine tree, but I couldn’t see them. Noisy critters, though. I also saw a Red-Shouldered Hawk fly up from the high dried grass on the ground, cross the trail, and into a tree. I don’t know what it had on the ground, but it wasn’t in the bird’s talons when it flew up.
Acorn Woodpeckers were in one of their granary trees buzz-bombing a California Ground Squirrel that had gone high enough into the tree to steal some of their acorns.
I also saw a scruffy-looking Scrub Jay bopping around with a large Green Darner dragonfly in its beak. It didn’t eat the dragonfly, though; instead, it buried it in a shallow hole under some leaves for later.
And in another area, I was watching some Rio Grande Wild Turkeys walking through the tall, dry grass, and saw the dark forms of quail scurrying out from under the big birds’ feet. I could hear the quail calling and pipping to one another, too, but I couldn’t get a clear photo of them.
I walked for a little over 3 hours, and then headed home. This was hike #69 on my annual hike challenge.
