Gall Hunt, Part One, 08-27-21

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 Spiny Turban galls.

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.

A Lifer Bird and the Bugs, 08-24-21

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.

Sacred Lotus, Nelumbo nucifera, flower and Western Honeybees, Apis mellifera

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.

American Crow, Corvus brachyrhynchos, mid molt.

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.

A Morning Walk at Mather, 08-20-21

I got up about 5:30, let the dog out to pee, and then went back to bed until about 6:00 am.  Not a long stay-in but I needed that little extra bit of rest before heading out to the Mather Lake Regional Park for a walk. It was very smokey again here today and the air quality level reached  163 AQI (Unhealthy)  by the afternoon. Still, it’s not anywhere near as bad as it is closer to the wildfires, where the air is considered HAZARDOUS. It was a cool 55° outside when I got to the park, so it was actually nice to walk in.

When I arrived at the park, I was the only person there, so I had the place all to myself for about an hour. By the time I left there were still only about 6 people there; all of them fishing. I hadn’t gone there with any agenda in mind, so I was open to whatever Nature wanted to show me today.  I saw a little bit of this and that.

The willow galls are evolving. I saw Apple Sawfly galls, bead galls, and plump pinecone galls. And the cottonwoods are done “cottoning” and the leaves are already starting to turn yellow. I found both petiole and leaf galls on them.

The bugleweed is in bloom right now, and there’s still a lot of pennyroyal and smartweed flowering along the water’s edge. I also found a patch of large Pinkweed, also called Big Seeded Smartweed, some willowherb and goldenrod in bloom. All of the rushes and sedges are also growing like gangbusters right now — even around the beaver den.

I found quite a few mature and juvenile Blue Dasher dragonflies resting in the grass. Because it was cool, they were all torpid and easy to catch.

Blue Dasher Dragonfly, Pachydiplax longipennis [white faced]

On the trail, there was a small pellet that might have been coughed up by a cormorant, or by some other fish/crayfish eating bird. It had red bits and what looked like pieces of legs in it. I don’t think it was defecated by an otter (because of its shape and size).

There was the regular cadre of Canada Geese and Mute Swans in and around the water’s edge. The juveniles are as big as their parents, but some of them still “peep” like babies.  I also got a glimpse of a Belted Kingfisher perched in a tree, and a pair of White-Tailed Kites flying overhead.

A pair of immature Mute Swans, Cygnus olor

I came across two coveys of California Quail, one on the trail and another in an adjacent field. They run around like idiots, pipping and calling to one another. Crack me up.

There seemed to be Black Phoebes no matter where I looked. They seemed to be following me. There was also a Red-Shouldered hawk that I seemed to see in different trees all around the lake.  I could hear him screeching from here and then from there.

Black Phoebe, Sayornis nigricans

On the far end of the lake, there were lots of gallinules in the water and along the edges of the tules. Most of them have their red face shields now, and their candy-corn colored bills.

As close as the lake is to the Mather Air Field, it’s not unusual to see fighter jets flying around, but today I saw a variety of helicopters flying overhead. I think they were CalFire units.

I was able to walk the whole trail from the parking lot to the fence along the golf course and was out for about 3 hours before heading home. This was hike #71 in my annual hike challenge.

Honeydew Galls and Drippy Nuts, 08-18-21

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. 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!

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.

Anyway, 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.

Round Gall Wasp, Cynpis conspicuus [round gall near base of leaf on Valley Oaks, formerly Besbicus conspicuus]

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.

Yellowjackets, Western Yellowjacket, Vespula pensylvanica

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.

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.

The stand-out on the live oaks was the number of acorns affected by Drippy Nut, Brenneria quercinaLonsdalea quercina, a bacterium that infects wounds in oak tissue/acorns. Lots of dark acorns, lots of “foaming” ones.

I also found one that looked like an unfertilized “female flower”; nothing was attached to the cap except 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.

CLICK HERE to see the full album of photos.

I also found an Assassin Bug nymph on some of the rushes by the water.

Assassin Bug, Leafhopper Assassin Bug, Zelus renardii [nymph]

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.
