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.

Blue Oak Galls and Other Stuff, 07-09-19

I headed out to the Effie Yeaw Nature Preserve.  It was about 56° when I got there, but it was up to around 75° when I left.  When I got there, I was happy to see my friend and fellow-naturalist Roxanne there, too. She’s helping me out with the Monarch monitoring facet of my volunteer work at the preserve. I really appreciate her help, too, because it makes the somewhat tedious process of looking over each milkweed plant go more quickly. 

Still no sign of Monarch eggs or caterpillars, and what was odd was we didn’t see much in the way of other insects either.  We did find some spiders (including a White Crab Spider and a little Jumping Spider), some aphids, a single praying mantis, and a couple of beetles but that was it.  The lack of critters was rather surprising and made me wonder if the area had been sprayed or something.  We worked on the plants for about 90 minutes and then went for a short walk through the preserve.

 Although we heard a lot of different birds, we didn’t see any Wild Turkeys today, which was very unusual. They’re normally all over the place. We came across two bucks but no does and no fawns. Both bucks were in their velvet.  One was a nervous youngster who was just getting his first antlers (a “spike buck”), and the other was a laid-back 3-pointer who was just lying in the grass on the side of the trail.  He kept an eye on us but didn’t move from his spot. I guess he figured we were no match for him, so we weren’t much of a threat.  He was gorgeous. And because he was so still, we were able to get quite a few good photos of him.

CLICK HERE to see the album of photos.

The most exciting thing to me that we came across on our walk was sighting a few different species on a Blue Oak tree (Quercus douglasii) along the River Trail.  It had both Saucer Galls (Andricus gigas) and newly budding Crystalline Galls (Andricus crystallinus). The saucers start out flat and then form cups (some with smooth edges and some with serrated edges). The Crystalline Galls start out like tiny dark-pink urns and then swell up and get their sparkly spines. We hadn’t seen any galls at all on the “Frankenstein” hybrid tree further up the trail, so finding the galls on the Blue Oak by the river was rewarding. 

It was nice to see that this particular Blue Oak was also getting acorns on it. These oaks don’t produce acorns in drought years, and when they do produce acorns, they’ll produce a lot one year (a “mast” year) and then produce far fewer for the next two or three years.  So, as I said, it was nice to see this one with acorns all over it.  (The acorns usually take a year to develop.) Blue Oaks are also endemic to California, which means they’re found here and nowhere else on the planet.  It’s also one of the oak trees that is immune to the fungus that causes Sudden Oak Death.  Very cool trees.

Oh, and we found a Treehopper – but it jumped away before I could get a photo of it.  Those things are sooooooo weird-looking with their hunched backs. The one we saw was a Buffalo Treehopper (Stictocephala bisonia): mostly green with some burnished gold edges on it.

We walked the trails for about 2 hours.

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.

Lots of Critters… and a Beaver, 06-20-19

Up at 5:00 am again. I let the dog out to go potty and fed him his breakfast then headed over to the Effie Yeaw Nature Preserve for my weekly volunteer Trail-Walking gig.  It was a gorgeous 58° when I got to the preserve and was overcast, so it never got over about 68° while I was there.  Perfect walking weather.

CLICK HERE for the full album of photos.

One of the first things I saw was a Red-Shouldered Hawk carrying nesting materials. First she flew over my head, then she landed on a tree to get a better grip on the grasses she was holding before taking off again. These hawks only have one brood a year, but often work on the nest throughout the year to keep it clean.  It’s no uncommon for them to use the same nest over several season if the first nest is successful.  Later in my walk, I went by where I knew one of the hawks’ nest was and found a juvenile (fledgling) sitting out beside it squawking for its parents to come feed it. It was capable of feeding itself, but some of these young’uns milk the I’m-just-a-baby thing for quite a while. While it was near the nest, it was hard to get photos of it because it was backlit, but later it flew out and I was able to get a few better photos of it when it landed in a nearby tree.

There were a lot of deer out today, but I didn’t see any fawns. I DID see a couple of bucks, though, both of them still in their velvet, a 2-pointer and one with wonky antlers (one super-long one and one stumpy one). The 2-pointer was walking with a doe, and when I stood on the trail to take photos of them, he decided he didn’t like that.  He stepped right out toward me with a very determined look on his face. (Bucks can get real possessive of “their” does.) I knew he wouldn’t rush me and try to gore me because he was still in his velvet.  In that state, the antlers are super-sensitive to touch, and if he rammed me, he’d actually hurt himself.  But, he could still outrun me mash me with his hooves if he had a mind to, so I put my head down and back away.  That seemed to be enough of a submissive posture to him, and he returned to his doe.  As beautiful as the deer are, I have to remind myself that they’re still wild animals and will do whatever their instincts tell them to do – even in a nature park.

I heard and caught glimpses of several Nuttall’s Woodpeckers on my walk, but never got enough of a look at one to take its picture. Those birds enjoy teasing people, I swear. They’re really loud about announcing themselves in flight, but then hide from you once they land.

The wild plum and elderberry bushes are all getting their ripened fruit now. I saw birds eating some of the berries and came across an Eastern Fox Squirrel breakfasting on the plums.

Along the river, there was a small flock of Canada Geese feeding (bottoms-up in the shallow water) with a female Common Merganser fishing among them. They eat different things, so the geese were stirring up the water plants and the Merganser would grab any small fish that appeared. Unintentional mutualism.  While I was watching them, I saw something else in the water, swimming against the current and realized it was a beaver! 

I went down as close to the shore as I could – (It’s hard for me to clamber over the rocks.) – and tried to get some photos of it. Photo-taking was difficult because the beaver stayed close to shore and was obscured by the tules and other riverside plants and scrubby trees. When it got into less cluttered spots, in was in the shade, and my camera had trouble focusing between the dark and the reflections on the water.  So, I walked ahead of where I thought the beaver was heading to a sunnier spot and waited for it… and waited for it… and then I heard a splash and realized it had swum under the water right past me and came up in the river behind me.  Hah!  Sneaky Pete!  

I walked for about 4 hours and then headed back home.

Lots of Snowy Egrets, 05-31-19

I got up about 5:30 this morning, fed the dog his breakfast and then headed out to the Cosumnes River Preserve for a walk.

There was little to no water in the “wetland” areas, so not a lot of birds or dragonflies. I walked along the slough on the side of the road, and then walked through the oak woodland to the nature center, and then back to the car.  Along the slough, I saw Tree Swallows, a pair of Western Kingbirds, and a trio of Brown-Headed Cowbirds doing their bowing thing. They were on the top of a tree, so bowing was difficult, and they kept rolling off their twiggy branches. Eventually, they gave up and flew off.

Further along, I came across a small flock of Snowy Egrets who were feeling for things in the water with their feet.  As I was watching them and taking pictures, a Great Egret flew in and joined them. Seeing the great Egret and the Snowy Egrets side-by-side really exemplifies their size difference. It looked like a mama bird with lots of babies around her.  Some of the Snowy Egrets were flashing their top knots at one another. I got the sense that it was a more an aggressive, territorial thing than a romance thing. None of the birds had their long, trailing feathers in; and none of them were sporting the pink blush in the face the Snowies get when their breeding.

Beyond the regular Oak Apple galls, there weren’t a lot of other ones out yet. I saw some Red Cones just starting to grow – looking like tiny red pimples on the leaves of some of the Valley Oaks.  I did see the curling leaf galls and “flower” galls on the ash trees, but not as much as I’m used to seeing.

As I was walking through the oak woodland, I was surprised to see a large flock of American White Pelicans fly overhead. By the time I got my camera up and focused, though, they were gone. It’s always so neat to see those big birds flying.  They don’t look like they should be able to stay aloft, but they’re so graceful in the sky.

I also got a glimpse of a Green Heron when he flew out from the rushes around the bridge area, and up into a willow tree.  There were so many twiggy branches around him, though, it was hard to get any decent shots of him.

Near the nature center, I saw some House Finches, Anna’s Hummingbirds, and a baby cottontail rabbit. The baby was a surprise; my brain couldn’t get itself around how small it was at first, and I just stared at it. I did come to enough to get a few shots of the bunny before it scrambled away, though.

Even going down to the boat launch area, I was surprised by the lack of insects. I was hoping to see dragonflies, damselflies and spiders there, but… nothing.

I walked for about three hours and then started to head home.  My insides were starting to complain, and I hurried to the restroom near the boardwalk area where my car was parked – only to find that the thing was locked shut. Seriously?! Guh! I hate it when that happens.

Bugs and Birds Mostly, 05-29-19

I got up at 5:30 this morning. I would have slept in a tiny bit more, but Sergeant Margie needed to get outside to pee. Since I was up, I decided to stay up and head over to the Effie Yeaw Nature Preserve for a walk. It was about 55° when I got there, and almost 70° when I left.

I saw a lot of the usual suspects at the preserve. Still very few deer around; the boys are off getting their antlers and the girls are off getting ready to give birth to their fawns.

CLICK HERE to see the album of photos.

I did get to see another pair of Mourning Doves working on their nest. I saw the male first, along the trail picking up twigs and bits of dried grass and flying them over to the female. She was sitting in the back of a half-fallen branch of a tree, tucked in a broken bit of bark. Smart girl!

Later on, along the trail, while I was watching a young Fox Squirrel, a California Ground Squirrel showed up, and then a Scrub Jay landed nearby with a green plum in its beak. Wow, lots of photos just within a few feet of one another. I love moments like that.

I walked for about four hours and then headed home.
