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.

A Few Birds at the Cosumnes Preserve, 03-24-19

I got up around 6:30 and headed over to the Cosumnes River Preserve to see how things are shakin’ there.  It was about 44° when I headed out.

I was actually kind of disappointed. Even through a 4-hour walk which really taxed my body, I didn’t see as much stuff as I was hoping to. The ponds near the boardwalk parking lot were virtually empty. Handfuls of birds here and there; most of them out of range of my camera. Along the river trail I startled a Cottontail who, if he had been still, I would have passed by completely. But he decided to make a dash for it, then stopped out in the open. Must’ve been a young one; the adults know better than that.

I also got to see a Black Phoebe mining mud, I guess, from UNDER the boardwalk (I guess all of the other mud in the place wasn’t good enough for her). When she flew in under the boards, her wings and tail dipped in the water, and Phoebe feathers aren’t waterproof so she was kind of endangering herself with every dip.

Now, I assumed she was pulling mud OUT of there, but she may also have been creating a nest under the boards – although that seems really weird to me. If she was constructing her nest under the boards, it could be ruined if the water level in the ponds rises again (or the place gets flooded again). Phoebe nests are made primarily of mud, so if one got wet it would disintegrate, and the eggs or nestlings would drown.

I wished I could’ve gotten a camera under there to see what was really going on.

There also seemed to be an inordinate number of Audubon’s Warblers all over the property… and the Tree Swallows were vying for nesting spots in the bird boxes and the trees. But otherwise, I felt the trip was kind of a bust.

Eagles, Ravens and More, 01-28-19

I wanted to get up a little early today so I could head out to the Sacramento National Wildlife Refuge… The drive to the refuge is a long one: 2 hours there, 2 hours back, and about 4 hours of driving around the auto tour route. That’s a LOT of car time, sitting in a folded-up position. I haven’t done it since just before my surgery and didn’t know if my core could handle that yet. Well, I found out. It can’t right now.

I was okay on the drive there, but halfway through the auto tour route, I started to ache, and by the time I got back to the house I was in pain. Dang it! I thought I was doing so well. Gotta work more on the exercise and core stuff I guess.

Anyway, after putting gas in the car and stopping to pick up something for my own breakfast, the dog and I got to the refuge around 7:00 am. The sun was just coming up, so I got some red-sky photos. Because the light was so “low” and there was some cloud cover, the camera gave me fits all day. The cloud-glare bounced off the water and played havoc with the light meter/auto focus dealie, and I struggled to get the photos I wanted, sometimes failing miserably which was very frustrating. So, rather than relaxing me, I was kind of stressed out periodically throughout the drive.

Still, I did manage to get SOME halfway decent images. CLICK HERE to see the full album.

The standouts for the day were the Bald Eagles and Ravens. I saw about 5 eagles, including a bonded pair and a juvenile (maybe 2 or 2 ½ years old). One of the eagles was sitting what I generally call “the eagle tree” because you can often find one sitting in it.

It’s sometimes hard to get photos of the birds in that tree because it’s a tall one that sits on the right-hand side of the road. You either have to lay down in the front seat and shoot out the passenger-side window or turn the car at an angle that puts your driver’s-side window to the tree (and blocks the whole road). There were no other cars on the road at the time, so I chose to block it. (Didn’t think my core could handle my lying down in the seat and twisting to shoot out and up into the tree.) I was surprised to find that in that tree, on a few branches below the eagle, there was also a Cooper’s Hawk. You don’t really realize just how truly big the eagles are until you see one beside a hawk. Wow!

The rest of the eagles were near the end of the auto-tour route. The bonded pair were in a distant tree, sitting near the top of it, near the last park-and-stretch area. Because they were so far away it was hard to get any good close-ups of them with my camera. And because of the cloud-glare, their white heads tended to vanish against the white sky, so finessing the camera’s iris was tricky. I liked watching the pair, though. They sat side by side, surveying the surrounding wetlands, periodically touched beaks like they were kissing and groomed one another.

The last two eagles, an adult and the juvenile, were sitting up in the eucalyptus trees along the exit route. The juvenile, which was much more visible than the adult because it was sitting out near the end of some branches, at first looked like a mottled shadow against the twiggy branches, but then seemed to reveal itself as I got closer to it. So cool!

I also got to see three ravens. Two were of a pair that landed together in a tree near the end of the auto tour route. One was kind of bedraggled-looking; some of its feathers were on inside out. And the other flew up with it, offering it a treat I couldn’t quite make out. The treat-bearing one flew off again, and the bedraggled-looking one stayed behind, cawing loudly in the direction in which the other had left.

Even though I wrestled with the camera all day, I was still able to see over 30 different species of birds and animals while I was out there, so I still chalk it up as a “good” viewing day.
