CalNat Field Trip #2, Lake solano Park, 07-13-19

On the way to Lake Solano Park for our second Certified California Naturalist field trip of the summer, I stopped to put some gas in my car, and I was treated with the sight of some hot air balloons floating over the city of Winters and its surrounding fields. One of the balloons was either dragging or coming in for landing because it got REALLY low over downtown. I could see the people in the basket.  I was kind of surprised to see the balloons at all considering that it was already about 62° when I got to Winters.  Hot air balloons only work if the air around them is cooler than the air in the balloon (so they fly more successfully in the fall-to-spring time period than they do in the summer.)

I was the first one in our group to get to the park and pulled up into one of the upper parking lots because the lot nearest the park itself was still closed.  Technically, the park doesn’t open until 8:00 am, so I was there before the all-gates-open time. The rangers weren’t too pleased that I was in the upper lot before 7:30 am, but they didn’t say anything – until AFTER 8:00 am and my students had arrived, and we were in the park area itself.  I’ll know better next time not to get there early.

The reason for trying to get my group there earlier in the day, though, was to try to beat the heat. It got up to 79° by 10:30 am. So, we cut the trip a little short to get everyone back in their air-conditioned cars before we all overheated. Along with my co-worker Bill and most of the students in the class, Greg Ira (the Director of the Certified California Naturalist program at the University of California) joined us for our walk.

One of the first things we pointed out to the group was the difference between the native Black Walnut trees and the English Walnut trees. English Walnut trees don’t generally do good in California, so they’re grafted onto the native Black Walnut root stock. We were able to show the students the graft mark in one of the trees (with the Black Walnut on the bottom and the English Walnut on top) and showed them that even through the tree itself was now primarily English Walnut, they could still see some shoots of Black Walnut stems and leaves growing up out of the root stock.

We seemed to hear more birds than we put eyes on, and my student Alison K., who like our student Ken E., is a birding expert, helped us with the sound IDs.  Alison also told the group about the sap wells we were seeing in the bark of some of the trees, created by Sapsucker birds who drill the wells not so much to suck the sap, but to attract insects they can eat.  On one tree we found several clear samples of the wells, along with some hefty outpourings of the sweet sap.

We also came across a large juvenile Great Blue Heron that was sitting in a tree adjacent to the trail.  It posed for some photos, pooped into the river and then flew off with a deep-throated croaky squawk. I guess he told us what he thought about us. We also came across a small creche of Peahens with their fledgling poults. A group of three moms were taking the babies to the edge of the river to get a drink.

 I myself was focused more on finding galls than seeing birds on this trip, however, and was able to point out newly budding examples of Pumpkin galls, Roll Gall Midge galls, Erineum Mite galls, Cluster Galls, Spiny Turbans, Two-Horned galls and Flat-Topped Honeydew galls. Most of the galls were just starting to emerge and weren’t their full size yet.  Give them another week or two and they should be spectacular.

 Our group also found quite a few different orb-weaver spiders included Spotted Orb Weavers and Long-Jawed Orb Weavers. And we spotted a variety of butterflies, dragonflies and damselflies including: California Pipevine Swallowtail butterflies, a sleepy Buckeye butterfly, a Painted Lady butterfly, and a Tiger Swallowtail butterfly on the wing; Widow Skimmer dragonflies, Flame Skimmers, Four-Spotted Skimmers, Pond Skimmers and Blue Dasher dragonflies, plus several damselflies that looked like they’d just emerged and weren’t colored-up yet.

Along with imparting some of what I know to the class, I always learn something new on these field trips or add to knowledge I already have, so it’s always fun and exciting to me. I found two galls I hadn’t seen before and found out that even the experts were having trouble properly identifying them. One was a gall made by the Roll Gall Midge (whose species is known but not its genus) and it took the form of rolled edges along the leaves of Live Oak trees.  The other was an odd tubular “prick” on the leaf of a Valley Oak tree. At first, I thought I was just looking at a weird anomaly on the leaf, but then I saw the exact same structure repeated on leaves of different Valley Oaks, so I took some photos and looked it up when I got home.  Experts recognize it as a wasp-induced gall but they don’t know what species it’s associated with yet, and think it might be a second-generation gall for an already identified gall wasp.  Everything I found on it called it a “Leaf Gall Wasp” gall but with the species listed as “Unidentified”. How neat!

 As we were looking at some California Wild Grape vines, Greg asked for the term for the process by which tendrils wrap around things. None of us could remember it at the time. Of course, when I got home, it came to me: “THIGMOTROPSIM”! Cool word, huh?  You can read more about it here: http://biology.kenyon.edu/edwards/project/steffan/b45sv.htm

Another word that wouldn’t come to mind yesterday when we were out on the field trip… We saw a lot of damselflies that had apparently just emerged and weren’t “colored up” yet, and I couldn’t remember the term for that state.  It’s “TENERAL“: the state of an insect immediately after molting. At this time the insect’s exoskeleton has not hardened and it may be pale in color.

A little further along our walk, some of the students noticed frothy ooze coming out of the base of a Valley Oak tree. It looked something like Sudden Oak Death (SOD) to me, but it was a lot more frothy, and I’d never seen SOD near the bottom of a tree before. So, I looked it up when I got home.

 The foam is from a bacterial infection in the tree called “Alcoholic Flux” or Foamy Canker. It usually affects trees in the summer that have been stressed in some way. Bacteria infects the tree and ferments some of the sap. The fermentation is expelled by the tree in a frothy slime that kind of smells like sour beer. Unlike SOD, alcoholic flux isn’t usually a permanent or fatal kind of infection. It’s usually gone by the end of the summer.

We’d also seen a lot of small gnats around the ooze, and I’m not sure, but I’m going to infer that they were getting buzzed on the fermented juice. Hah!

By 10:30 it was already too hot to keep people out in the sun, so the group broke up and we all headed back to our cars by different routes.

Poults and a Snake, 07-04-19

Happy 4th of July.  Up at 5:30 am, and out the door before 6:00 to go to the American River Bend Park for a walk.  It was about 59°when I got there with a slight breeze blowing, so it was nice.  I was expecting the place to be crawling with people for the holiday, but nope. I had the trails almost to myself all the while I was out there. 

The very first thing I saw when I drove in was a doe crossing the road in front of me.  She stopped and looked behind her, and then I saw her fawn come out after her and scurry across the road, too.  I tried to get photos, but I had to shoot through the windshield so… nuthin’.  Dang it!  But the park was otherwise pretty kind, giving me two other surprises with better photo ops.

CLICK HERE to see the full album of photos.

The first of those two was getting the chance to see some Rio Grande Wild Turkey poults (Meleagris gallopavo intermedia). I hardly ever get to see them because the moms are so good at keeping them hidden. This was a group of three adults and five poults. The poults were all fledged in their first feathers but still too small to fly.  Among the adults was the leucistic (black and white) female I see often in the park. She was following after the other two, so I inferred that she was “learning” from them. She mimicked a lot of what they did, and also seemed to be helping out with protecting the babies.

At one point, one of the adults jumped up into an elderberry bush and started pulling berries off and dropping them to the ground so the babies could get them. A few seconds later, one of the poults got up into the bush, as well, but couldn’t reach the berries and jumped down again. So cute.  I think that little guy was blind on one side. It kept on eye shut all the time, and the lid looked “flat” in the socket (instead of rounded out by an eyeball).

I walked with the small flock for a while, but the adults were really good about keeping the kids out of the sunlight, for the most part, and keeping themselves between the babies and me. Who says turkeys are stupid?

The second surprise came when I walked down near the shore of the American River because there was a Buttonbush down there in full bloom and I think the flowers are so cool-looking. Anyway, while I was taking pictures of the flowers, I caught a glimpse of something moving past my foot and going behind me, so I turned around and saw a spotted snaky form slipping through the rocks.  At first I thought it was a gopher snake because they’re really common in the park, but then I caught a glimpse of the head. Not a gopher snake.

It was a young RATTLESNAKE. It was about as long as my forearm, so not too-too big, but still large enough to pack a good supply of venom. What was weird was: when I first saw it, it was in diffused light so all of the light parts on it looked pale blue and all of the spots on it looked kind of orangey. Very odd.

I followed after it a little bit to try to get more photos — which is hard for me on the shore because it’s all rocks there and my feet don’t work well on unstable cobbly ground.  I stopped when the snake got pissed off at me and wound itself into a striking position. Uh, yikes! I took just a few more photos and then let it be.

I also came across a small family of crows: a parent and two fledglings, I think. I saw the parent hand off a rock to the kids – which they weren’t interested in — and then pick up some seeds from along the shore.  The fledglings were very loud and fussy, demanding that mom feed them (even though they were large enough to fly and forage by themselves.) Huge mouths!  They cracked me up.            

Walking through the rocks on the shore, and then having to climb back up an incline to get to the trail pretty much did me in, though. The bones in my feet are “welding together” like Mom’s did from arthritis, so my feet don’t bend and flex like they should, which is why walking on uneven ground is hard for me these days.  Still, I was able to walk for about three hours total before heading back to the house.

Lots of Fledglings and Other Critters Today, 06-30-19

I got up around 5:30 this morning and immediately headed out to the Effie Yeaw Nature Preserve for my weekly volunteer trail walking thing.  It was cool, around 55°, when I got there, but as soon as the sun got up a little higher in the sky it started to heat up.  It ended up around 75° by the time I left the preserve.  There were some latent clouds overhead which meant it was humid, too. Not my favorite.

Along with the usual suspects – deer, Acorn Woodpeckers and Wild Turkeys – I got to see quite a few fledgling birds out today.  The fledglings are fully feathered and the same size as the adults, but not quite adept at flying yet, so they spend a lot of time around ground level begging their parents to feed them.  They’re so bossy!  I watched one little House Wren fledgling sitting on top of a pile of old tree limbs.  For a while, he tried posturing like the adults do with his little tail standing straight up behind him, but then he got tired and just sat and dozed… until he saw or heard one of his parents flying by. Then he’d perk up and open his mouth wide expecting food to be dropped into it. Hah!  Although I could see the parents flitting around where he was, they also had other fledglings in the nearby shrubbery (which I could hear buzzing away), and because I was standing between the shrubs and the baby on the woodpile, they wouldn’t go near him. After getting quite a few photos of the little guy, I decided I’d better move on or he wouldn’t get fed at all.

I also came across two fledgling California Towhees.  Now, the California Towhees usually look kind of obese and drab to me, but the babies… they were soooo scrabbly looking; total bed-heads!  They were sitting close to one another with their feathers all fluffed out, so they looked extra fat and messy. Made me chuckle.  One was content to sit and wait for their parents to bring breakfast, but the other one was extra hungry, I guess, and kept tugging at the dead grass near them trying to get something out of it. Can’t get milk out of a stick, son. Sorry.

Further on along the trail I could hear a parent and fledgling Red-Shouldered Hawk calling to one another.  The fledgling was very loud and persistent, demanding to be fed, and the parent would call back him as if to say, “Shut up! I’m working on it!”  I eventually came across the fledgling sitting up in the bare branches of a tree. (He was so loud he was announcing to everyone exactly where he was.)  He saw me and tried to scramble away to other branches but was still unsure of how to make his wings work, so he looked pretty clumsy.  He stuck to the shadows as much as he could then, but I was still able to get a few photos of him.  (And I’m assuming he was a male based on his coloring; females are usually larger and have less vivid colors.) 

I also found one of the parents, sitting quietly now in the low branches of another tree right along the side of the trail, just above eye-level, ignoring the fledgling. Totally habituated to people, it didn’t move from its perch, but kept its eye on me as a passed by and stopped to take some photos. I think they’re such handsome birds.

CLICK HERE for the full album of photos.

Among the other things I found today were a few Pumpkin Galls on the leaves of a Live Oak tree. It’s kind of early in the season for those, so I was surprised to see them.  They’re super-tiny galls, and if you don’t know where or how they develop you’d completely miss them. Right now, they’re pale green, but come fall they’ll turn dark orange and fall off the leaves onto the ground were the little larvae will pupate through the winter.

I found a few Eastern Fox Squirrels and some California Ground Squirrels.  I was surprised to see one of the Fox Squirrels climbing through poison oak and eating the berries! Yikes!  I mean, I knew that the toxin in poison oak don’t generally harm wildlife, but I’d never actually seen any of the animals eating the stuff before.  I also saw a Fox Squirrel eating the husk off of a black walnut and watched a Ground Squirrel eating the tops off of some other plants.  (I think that gal was blind on one side, but once she saw me she moved too fact for me to get photos of her blind side.)

The other cool thing I spotted along the trail was that feral honeybees have found the tree along the Pond Trail again and seem to be setting up house there.  I saw them last year (I think it was) checking out the big opening in the side of the tree, but they left the site after a few weeks.  I guess the queen didn’t like it.  Now the opening is more covered with plants, so maybe it will feel more “protected” to them and they’ll stay there this time.  I let the gals in the nature center know they were there, so hopefully they can discourage hikers from walking off the trail to see the bees. We’ll see.

Wren Housekeeping and Slime Molds, 05-21-19

I got up a little before 6:00 am and headed over to the Effie Yeaw Nature Preserve for my regular Tuesday trail-walking gig.  It was cool and rain threatened, but it didn’t actually start raining until I got back into the car to head home, so that was nice.  I was joined on the walk by Mary Messenger (The Other Mary), and we took the trails in a counterclockwise fashion just to mix things up a little bit. I was hoping to see the young coyote again, but I didn’t.  Later, Rachel (the volunteer coordinator) told us that she’d spotted it in the company of a larger coyote in the big field right before the turn off to the nature center.  She suspected it was too-lean female, but I think it’s a juvenile.  Hard to tell, though, unless we can get a really good look at it.

CLICK HERE for the album of photos.

I did get to see couple of slime molds, which was cool, and also got to watch House Wrens doing their daily chores: bringing twigs and feathers to line their nesting cavity; bringing breakfast to the kids; and taking out the trash (taking the babies’ fecal sacs out of the nest).  We also got photos of a cooperative Desert Cottontail rabbit who was eating clover along the edge of the trail.  So cute.

We walked for about 3 ½ hours and then head back home.

Lots of Nesting Birds, 04-30-19

I got up around 5:30 and was out the door by about 6:15 am to go to the Effie Yeaw Nature Preserve for my regular Tuesday trail-walking gig. The weather was beautiful: about 53° when I got to the preserve and about 70° when I left. Sunny and a little bit windy.

I saw LOTS of birds’ nests: European Starlings bringing some twigs for the nesting cavity and some bugs and worms for the hatchlings. (I could hear the babies squawking inside the tree); Phoebes bringing bugs for their babies; an Oak Titmouse carrying fecal sacs out of her nest; a male House Wren showing a nesting cavity to a female, even going to far as to get into the cavity himself, stick his head out and sing to her. Hah!

CLICK HERE for the album of photos.

Saw lots of squirrels, especially young Fox Squirrels who were running around, jumping, and putting just about everything they could into their mouths.  Generally, acting “squirrely”. Hah!

I found some caterpillars I’d never noticed before on the Redbud trees. They were pale green and had folded themselves inside the soft leaves of the tree.  You’ll never guess what they’re called…  Redbud Leaf-folder Moth caterpillars. Sometimes the names are like, “Duh!”, obvious.

I also found caterpillars on the leaves of the blackberry bushes, and these guys were tricky. They had an escape hatch, so if I touched the front of their silk “nest”, they would zip out the back and fall onto the leaf below them. Some of them had black faces and some of them had reddish-tan faces. I haven’t really ID-ed them yet.

And, of course, there were Tussock Moth caterpillars everywhere.  Here’s a video snippet of an active guy on the top of one of the water stanchions at the preserve: https://youtu.be/Bj9nZiy_EmI

I think I’d mentioned before about the fact that I was finding tiny dirt-clod turrets on the trail.  They look like “hoodoos”; y’know like the big stone ones at Bryce Canyon, but on a tiny-tiny scale.  I couldn’t figure out what was making them, so I put my naturalist students on the hunt for information. Naturalist graduate Deborah Dash sent me some photos of the Diadasia bees and the turrets they make, but all of the photos were from the top of the turrets not the side, so I couldn’t really compare them to the photos I had.  But, that tip led me to look up other Diadasia bees, and I think I found the right one.  I now believe these are the turrets of the “aggregate nests” of the solitary, native Mallow-Loving Digger Bee, Diadasia sp., subgenus Coquillettapis, This website shows how the turrets are created. So neat! (http://nathistoc.bio.uci.edu/hymenopt/Diadasia%20Coquillettapis.htm)

Near the end of my walk, I couldn’t understand why I was so frigging tired. Then I looked at the time and realized I’d been walking for FIVE HOURS!  Yikes!  I get so wrapped up in what I’m seeing on the trail that I lose track of time.

It was “Buggy” Out There Today, 04-27-19

I got up a little before 6:00 am and headed out to the Effie Yeaw Nature Preserve for a walk.  I wanted to get there by 6:30 so I could beat the heat for today.  Actually, the weather was rather pleasant all day, but anything over 70° is uncomfortable for me when I’m outside.

When I got there, The-Other-Mary, Mary Messenger, another volunteer trail-walker at Effie Yeaw, was there wanting to join me, and my friend/naturalist/volunteer Roxanne Moger also showed up. So, we had a nice time looking at all the little stuff that was around us.

CLICK HERE for the full album of photos.

Roxanne and I were more focused on bugs and galls this time around than the larger animals, so we were moving really slowly, investigating the leaves of plants and using the macro-settings on our cameras.  I actually like the quality of the macro-photos better on my cell phone than on my camera (it can get in tighter and more clearly), so I was using that a lot.  The best finds of the day were made by Roxanne who discovered a Tiger Swallowtail butterfly in a tree and a California Alligator Lizard hiding in some clover.  The alligator lizards are super-common in Southern California, but we don’t see them much here, so finding one is always fun.

We located a Black Phoebe nest, found out where an Oak titmouse was hiding out in a tree (that was guarded at the moment we saw it by a Western Fence Lizard), and also saw a Starling leave her nesting cavity with a white glob in her beak. She threw the glob down in a field and kept on flying.  I’m assuming she was doing housekeeping and tossed the babies’ fecal sacs.

We saw a few deer, including a pair of bucks in their velvet. One of the bucks decided to do a head-scratching maneuver that, at the same time, flashed his junk at us.  Hah!  How rude!  I also came across a doe who was having a sneezing fit.  I don’t know if she snuffled up something while she was browsing or what, but she was loud!

The elderberry bushes are just starting to flower-out, as are the Buckeye chestnut trees. The few plum trees in the preserve already have plums on them, and some were starting to turn purple.

On the walk, we came across both Oak Apple wasp galls and Live Oak wasp galls.  And, as for the insects, I saw Pipevine Swallowtail caterpillars and butterflies, Painted Lady caterpillars and butterflies, some Tussock Moth caterpillars, Craneflies, some bumble bees, hover flies, damselflies (including a male and female Pacific Forktail), Soldier Beetles, ladybugs, aphids and some Spittle Bug spit and other critters. There are so many teeny-tinies around.

By this time of the spring, some of the butterflies are already looking pretty ragged. I saw several of them with tears in their wings and frayed edges.  I think some of the damage is done by the grasses that grow up around the flowers and plants the butterflies utilize. The razor-edges of the grass can cut human skin, so I can only imagine how quickly they can damage the fragile wings of the butterflies.

I walked for about 4 hours and then headed home.
