The 1st Summer 2019 Naturalist Field Trip, 06-15-19

I got up at 4:00 this morning, got the dog fed and outside to pee, and then headed out to Woodland for our first field trip for the summer naturalist class.  I got to the Woodland Library around 5:45 am and waited for my coworker Bill and the students arrive. The weather was VERY cooperative today. I was worried that the summer heat would make our field trips unbearable in the summer, but today it was nice.  It was in the low 60’s when we headed out, and only about 78° when we came back, so that was great.  There was also a slight breeze which helped, too.

When everyone got to the library and had signed in, we all headed out to the Sacramento National Wildlife Refuge.  I left my car in the parking lot and went with Bill in his van along with our student, Jeanette, who is a middle school teacher.

  • Locate and identify at least fifteen (15) animal species (birds, amphibians, reptiles)
  • Locate and identify at least ten (10) plant species
  • Locate and identify at least ten (10) insect species

While we were walking around the nature center, I think they all got the majority of those requirements!  The insects were probably the most difficult for everyone, but we’ll see on Friday (at class) how well everyone did. 

Near the nature center, we came across a large fat weevil sitting on the top of the flowering head of a tule.  Bill rapped on the weevil a couple of times and figured it was dead, but when I stroked it, its feet moved, so we all inferred that the weevil was in a state of torpor, waiting for the sun to get a little higher in the sky so it could warm up more and start moving around. 

Everyone took photos of it and tried to identify it using the iNaturalist app we’d told them about in class on Friday.  It came up as a Billbug Weevil from the genus Sphenophorus. If you look at the map in iNaturalist, though, you’ll see that Billbug Weevils have been sighted all over the globe. So, calling this a Billbug Weevil is somewhat accurate, but for a more precise ID, I wanted the students to try get down to the species level on the weevil when they got home. Insects can be especially hard to ID because there are literally millions of them, and you have to deal with taxon levels that include superfamilies, tribes and subtribes before you can get close to the species. It will be interesting to see how far the students are able to get.

We also found a buckwheat plant that I didn’t recognize as buckwheat at all because its shape wasn’t like any buckwheat plant I’d seen before.  The signage by the plant said it was California Buckwheat, Eriogonum fasciculatum, as did iNaturalist, but that didn’t quite look right to me. The leaves were the wrong shape.  So, I did a little more research, and I believe it was actually St. Catherine’s Lace, Eriogonum giganteum, a kind of wild buckwheat that usually only grows in Southern California. When we were studying the plant, two of the students (Jeanette and Edna) also observed that some of the flowers still had their pink pollen balls and others did not… and we inferred that those that didn’t have their pollen balls anymore had already been pollinated.

When it came time to drive the auto-tour route, I drove Bill’s van so he could do more observations, and Jeanette and another student, Mica, a retired farmer, came along with us. Bill was able to open up both sides of his van, so the gals could get an unobstructed view of what was out on the preserve. Although everyone was able to go at their own pace along the route, we stopped at two of the park-and-stretch areas so we could compare notes and get a closer look at things.  At the first stop, the students Ken and Alison, who are already expert birders, were helping the students spot and identify bird species and also explained what they meant when they talked about the birds’ GISS.

GISS stands for “General Impression, Shape, and Size” (originally a military term). Birders often use the bird’s GISS as a way to do a preliminary or in-field identification of a bird when it’s backlit (only seen in silhouette) or is too far away to see any details of its coloring. So, Alison and Kent were able to distinguish a pair of Northern Harriers flying over our heads from the Red-Tailed Hawk that was flying near them by nothing but their GISS. Very cool.  I’m nowhere near being that kind of an expert. 

At the second park-and-stretch spot, students relaxed with their lunches for a little while, and I was able to find a couple of examples of a specific kind of gall to tell them about, a Cottonwood Petiole Gall and is created by the aphid, Pemphigus populitransversus. The wingless female aphid called a “stem mother” chews at the leaf petiole (the stalk that joins a leaf to a stem) until it swells and then she climbs inside the swelling and has her babies inside of it. The baby aphids are born live and can be in either a winged form (called an “alate”) or without wings.

While the students were resting and checking up on their notes, one of them, Alison, let us see what she’d put into her field journal for the morning. She’s an artist, and she uses fountain pens and watercolors to write and decorate her entries. It was beautiful. I can hardly wait for Friday when all the students share their journals, so I can take photos and let you see what they’re doing…

I also overheard a couple of students talking about how much they enjoyed the class, how much they’ve learned already (in just two sessions) and how many resources we’ve introduced them to that they didn’t even know existed before now.  That is so gratifying!

One more learning moment: On the eucalyptus trees along the end auto-tour route on Saturday, I also stopped to pull a leaf off of an obliging eucalyptus tree, so I could show the students in our vehicle the white teepee-like formation on it that some folks mistake for galls.  The formations are actually called “lerps” and they’re created by a tiny insect called the Red Gum Lerp Psyllid, Glycaspis brimblecombei. These insects spin little white houses for themselves made of sugars and wax pulled from the leaves. They’re often very sticky with the honeydew produced by the insects.             

When we were done with the tour, everyone went their separate ways.

Trying to Beat the Heat on 06-05-19

I got up around 5:00 am this morning so I could get out to the Effie Yeaw Nature Preserve before it got too hot outside. The predicted high for today was 100°. When I got to the preserve, it was already about 67° outside.

Just seconds after I arrived, my CalNat graduate/friend, Roxanne M., showed up to join me and so did “The Other Mary”, Mary M., another volunteer trail walker at Effie Yeaw.  She brought a small bag for me filled with blackberries from her yard. I thought that was so nice of her.

The three of us walked for about 3 hours, but we cut out walk short because it was humid and hot at the river. When we left, it was already about 80°– and it was only a little after 9 o’clock. Pleh!

We weren’t expecting to see a lot, because nature is kind of in a transition period right now. We’re waiting for mammal babies to be born and insects to start showing themselves.  And, we didn’t see a whole lot, but Roxanne and I can always find something to look at and focus on.

Roxanne is doing a seed-collecting thing right now for the naturalist class, and so she stops at different plants to see what kind of seeds they have on them and how the seeds might be disbursed.  She took on this project on all by herself and is volunteering all the time it’s taking her to collect specimens and ID the plants.  I’m so proud of her!

CLICK HERE for the album of photos.

On our walk we saw a group of about four deer including a young buck in his velvet and a very pregnant doe. And later on, we also saw a bunch of baby rusty-headed Common Mergansers zooming down the riverside with their mom. It was so cute to see some of the babies swimming with their face down in the water, like the adults do, looking for things to eat.  Roxanne, The Other Mary and I all tried to get photos of them, but they moved so-so fast, it was really hard!

I also stopped to get some video of a hive of Common Black Ants (yeah, they’re really called that) carrying their larvae from one nest to another — most likely because the old nest was compromised in some way (infested with fungus, collapsing, etc.).

Moving the eggs and babies around can be really risky because they make for tasty treats for other insects and some birds, so the workers who carry them (very gently in their jaws) have to move really fast and know right where they’re going.

Queen ants are pretty awesome. They control the sex of all of their offspring (only creating males when it’s time for nuptial flights; ost ants you see are females); they can live for up to 15 (some say 30) years, and only mate during their nuptial flights… which means they can mate with several males during that short-term flight period, and then hang onto the sperm for the rest of their entire lives.

On our way out of the preserve we noticed leaves with circular cutouts on them. They’re made by Leafcutting Bees (Megachile sp.), a kind of native bee that lives in cavities. They use the bits they cut out of the leaves to line their tube-like nests and build a neat row of individual compartments, in each of which they’ll form a small doughy mound of pollen and nectar. On top of each of these mounds, the bee will lay a single egg.

Mother leafcutters can control the gender of their offspring, and often lay the eggs of their female offspring in the back of the tube-nest and the males in the front. This way, if the nest is invaded by a bird or other insects, it’s the males that will die first, leaving the females protected.

Although they’re solitary bees and don’t produce a lot of offspring, leafcutters are great pollinators. You can encourage them to pollinate your garden by building nesting boxes, called “bee condos”, for them in your yard. Here is a guide from the Xerces Society on how to do that: http://ow.ly/MhVf50uygX1.

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.

A Somewhat Disappointing Excursion, 05-23-19

Feeling tired and stressed, I decided to try making the drive to the Sacramento National Wildlife Refuge. Rather than being a therapeutic and relaxing time, however, I was faced with irritation after irritation, so the drive actually left me feeling more stressed and exhausted than I was before I started. *Heavy sigh*

CLICK HERE for the album of photos.

Traffic wasn’t too terribly terrible, but it seemed like I hit every freaking red light there was, and the monster semi’s on the highway were “always” in front of me like giant snails. When I got to the refuge, I could see Bank Swallows collecting mud in the slough near the front gate, so I stopped to take some photos – and, of course, the birds wouldn’t cooperate, and two employees pulled up in their cars behind me and honked at me. Grrrrr. The rest of the day kind of went like that: I saw Gallinules, but they ducked into the tules before I could get a photo; I could hear Bitterns giving their “pumperlunk” calls close by, but couldn’t see them; it was windy, so most of the birds were hunkered down near the ground or deep in the trees; where there would normally be dozens of Marsh Wrens around, I saw only two deep in the tules; the dragonflies hadn’t come up from the water yet; what damselflies there were around were the tiniest ones that are like trying to photograph a strand of hair; there weren’t any of the Clark’s or Western Grebes that I was expecting to be out there by now; I couldn’t even get shots of ground squirrels… It was just one frustration after another. By the time I left, I had a splitting headache and just wanted to ram someone with my car. ((I didn’t though.)) *Heavy sigh-2*

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.

Checking Out the Spider’s Den and Other Stuff, 05-18-19

I got up a little before 6 o’clock this morning and headed out to the Effie Yeaw Nature Preserve for a walk by myself.  I was trying to beat the rain – and was also on the lookout for slime molds.  I did beat the rain (it didn’t show up until around 3:00 pm), but I zeroed out on the slime molds. I think they need one more sunny day between the rainstorms to wake up.

It was nice and quiet on my walk, although I did come across a few other people. I was able to identify some birds to a couple who I think was visiting the place for the first time, and also directed a photographer to some good spots for photo opportunities. Doing my trail-walker thing.

CLICK HERE for the album of photos.

I saw a lot of the usual suspects: deer, turkeys, Starlings, House Wrens. I saw several bucks in their velvet, including the one with wonky antlers (one long and one short) and a torn ear. He should be easy to recognize from here on out.  And I also saw a doe with one ear that seemed really droopy. I don’t know what might have been bothering that ear; It didn’t look damaged or infected, at least as far I could tell.

A nice find was a male California Quail and one of his brides. I hear the quail at the preserve all the time, but they’re very fast and secretive, so I hardly ever get to actually see them.  This pair were pretty far away from me, across a meadow, but I was still able to get some shots. At one point, the male jumped up on a pile of brush so I could see him. They crack me up; their chubby little bodies look like light bulbs.

I also got to see quite a few female Common Mergansers going up into the cottonwood tree the Wood Ducks were in the last time. There were maybe three or four of the Mergansers, each flying around the tree and landing on different parts of it, quacking in low voices all the while. I don’t know if they were scouting out a nesting spot or were attracted to something else. I got some interesting-angle shots of them.

I was greeted by a pair of Western Bluebirds on another part of the trail. First the female flew in and then the male. They’re such bright, cheery-looking little birds. I always like seeing them.

And there was a very chubby California Ground Squirrel who popped up from her burrow to look around. I think she was pregnant based on her body mass. Their gestation lasts about a month, and then its another 6 to8 weeks before the babies emerge from the burrows. So, we won’t see them until sometime in July, most likely.

By the pond at the end of the Pond Trail were was some very fresh otter scat, so I’m guessing the otter was around there earlier this morning.  I’ve seen otters in that pond occasionally, but they usually wait until there are more crawdads around… The leeches in that pond might deter them, though.

I’m always curious when I find folded leaves or sealed leaf tents on plants, but I recognized what one was before I opened it when I found it on a mugwort plant. I handled it gingerly, and put it back where I found it afterwards.  Inside was, as I suspected, a mama American Yellow Sac Spider, Cheiracanthium inclusum, and her egg sac.

I was careful about how I opened it and handled it, because theses spider can pack a very painful bite (and are believed to bite more people than any other spider). The bite is said to burn like a wasp’s sting (and for sensitive people it can make them sick). The mother spider seals herself inside her rolled leaf tent with her egg mass, which can have as many as 100 eggs in it (although less is typical). She stays with the mass until the spiderlings hatch. After her babies hatch, she’ll stay with them until they’ve all gone through one molt (usually around 2 weeks).  As I mentioned, I set her and her tent back where I found them. She’ll spin new web to close her tent up again. ((Investigating leaf-rolls can be very interesting and rewarding for a naturalist, but just be careful.  You never know what might be inside of them.))

The young coyote showed up again today, in between two deer who didn’t seem to be aware that it was there.  It’s a very young coyote – gangly and thin, a teenager – but is hunting on its own, which I think is kind of unusual.  It moves too quickly, so I can’t tell if it’s a male or a female, but I did manage to get a few better photos of it today and a video snippet.

I got so preoccupied with my photo-taking that I lost track of time, and didn’t get back to the car until 11:30 am… So, I’d been on my feet for five hours. My ankles were killing me during the drive back to the house.
