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.

Mostly Pheasants and Marsh Wrens, 03-21-19

I got up a little before 6:00 am and headed out with the dog to the Sacramento National Wildlife Refuge.  I hadn’t been out there in a few months, so I was anxious to see what it was looking like.  I arrived there around 8:00 am and it was about 44° outside; when I left around noon, it was about to about 63°.  For the first half of my drive, the full moon was out, and all I could think was: I bet the Tiger Salamanders in Dunnigan are up and running around.  Hah!  Too much of a naturalist.

There “wasn’t much” to see at the preserve. Most of the large flocks of birds have moved on, and the summering birds haven’t arrived yet. What there was to see was mostly Ring-Necked Pheasants and Marsh Wrens… But there were other species as well, most of them too far away to get a decent photo of them. So, the day was a little frustrating for me. I did get to see some Black Phoebes building their nests under an overhang on the sign at the first park-and-stretch site, a pair of male pheasants squaring off against one another (although they were more interested in breakfast than in fighting), and a Great Egret fishing for crawdads in one of the sloughs.  One of the male Ring-Necked Pheasants jumped up onto a fallen log and “crowed”, then jumped back down and walked along the edge of a shallow levy to show off in the morning sun. He was unusually cooperative, so I got quite a few photos of him.  I saw a few Red-Tailed Hawks and some Northern Harriers (in flight); no eagles out today.

CLICK HERE for the album of photos.

Not a lot of wildflowers are out yet; it’s been too chilly for them. But I did see some Fiddleneck, and the pink Squirreltail Barley was all over the place.

I saw a small herd of deer cutting across one part of the wetlands, and one of the does looked VERY pregnant. Her belly was almost halfway down to her “knees”.

The Pool 2 Extension Loop was open, which was a nice surprise.  They’ve “manicured” some of the banks of the pool, though, knocking down and bending over some of the tules – which gives you a better view of the water, but means there are fewer hiding places for the birds (like the Bitterns), so you don’t get to see them. Can’t win.

The one thing that was out in abundance was the midges; they were everywhere, some of them in deep warming balls. Lots of food for the insectivores!

I drove around the auto tour route for about 4 hours and then headed home, getting there around 1:30 pm or 2:00.
