I got up around 5:30 this morning so I could get over to the Effie Yeaw Nature Preserve and begin my monitoring of my milkweed plot there for evidence of Monarch Butterflies. I finished that (with the help of my friend and co-naturalist Roxanne Moger) around 8:30.
It was still relatively cool outside, so Roxanne and I
decided to put our tools back into our car and walk for a little while. We came across some cooperative squirrels and
a Desert Cottontail rabbit, and also checked out the tree where I’d seen the
feral beehive earlier. There were about
three times as many bees at the spot, so I’m assuming the queen has decided to
set up shop there.
The surprise sighting was coming across another doe – with twin fawns! She was keeping them well-hidden in the shade and tall grass, but we were able to catch glimpses of them. And we couldn’t help but chuckle when the babies went stotting through the grass with mom chasing after them. They’re so tiny but soooo active! They’re the first fawns I’ve seen this year and that’s always exciting.
As we were leaving the preserve, I could hear a Ground Squirrel’s alarm call and looked around to see if I could spot what the trouble might be. I saw movement overhead and spotted an adult Red-Shouldered Hawk fly overhead. It landed in a nearby tree and then sat there for quite a while, so we were able to get quite a few photos of it. So, even though our walk was only a single loop, we got to see quite a bit… which is always fun.
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.
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.

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,
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
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.
