At the Ibis Rookery, 06-19-19

This was a busy day, but in a fun way.  I got up at 5:00 am and headed out to Woodland to go to the ibis rookery at the Woodland-Davis Clean Water Agency facility off of Road 102 and East Gibson Road. Then I headed out to the WPA Rock Garden, and later in the day, I attended a Monarch monitoring training. Phew!

 Last year when I went to the rookery, the water was a lot lower in the settling ponds. This year, the water is a lot higher, so all of the scrubby trees and tules the ibises were able to nest in before are now under water, and there was no real shore for them to rest on. All of the birds were clambering to get into the high branches of the few trees that weren’t submerged, and I saw some pretty brutal fights over nesting spots. I also watched as several of the birds pulled dried grasses up from the edges of the pond and flew them over to line their nests.

Some of the ibises, though, had already settled in, and a few of them already had eggs laid in their nests. The eggs are a bright neon-turquoise color so they’re easy to spot even at a distance. 

A mated pair of ibises near their nest.

Amid the ibises there were also Great-Tailed Grackles, American Coots (and a few babies), Killdeer, Black-Necked Stilts, Western Kingbirds and Western Meadowlarks. I also saw quite a few Black-Tailed Jackrabbits and Desert Cottontails. I saw Coot courtship behavior, which I’d never seen before. (I’d read about it but never saw it “live”.) The male and female chased after one another with their wings arched up and their tiny tail fanned out to show of the white patches on it.  They’re kind of dorky-looking birds to begin with, so seeing them hunched up trying to look sexy was a hoot. Hah!

CLICK HERE to see the album of photos. You can also CLICK HERE to access the feature article I wrote about the rookery in 2018 as published in the Lake County News online newspaper.

I took quite a few photos, but because the sun was coming up behind the birds, a lot of the stuff was in silhouette and I had to force the iris of the camera open to let more light in on the subjects.  I might go in again before class one morning to get different light. The area where you view the ibises is relatively small, so I was able to cover it in about an hour or so.

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.

Pemphigus populitransversus

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.

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.

CLICK HERE for the album of photos.

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.

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*

At the Sacramento and Colusa Wildlife Refuges, 05-06-19

Certified California Naturalist, Roxanne Moger and I went out to the Sacramento National Wildlife Refuge around 6:00 am this morning. The weather was beautiful today, but there wasn’t a lot to see at the preserve. We’re kind of in between seasons, so the large flocks of birds have all left, but the insects (like dragonflies, damselflies, and orb-weaver spiders) haven’t arrived yet. We did see swarms of Painted Lady butterflies and some Cabbage White, but none of the other species normally seen there in the late spring/early summer.

Roxanne did all the driving, but we stopped a couple of time to get out of the car and walk parts of the trail or explore the boundaries of the park-and-stretch areas. Some of the vernal pools on the site were in bloom: all golden yellow and purple with Goldfields and Downingia. Just beautiful.

Although the species list at the end of the day wasn’t as long or as varied as I’d like, I did like the fact that I saw a few things I’d never seen before and learned more about some species than I’d known before. That’s what really makes these outings fun.

A large fly landed on the passenger side mirror of the car partway through the auto-tour and at first I thought it was a Robber Fly (those guys are pretty big). We were both intrigued by the fly’s huge goggle-like eyes and his tenaciousness.  He held onto that mirror for quite a long time.

When I got home, I looked up the fly to see if I could find its scientific name and found that it was actually a male Striped (or Lined) Horsefly, Tabanus lineola. I’d never seen one before. And, of course, once I find something new to me, I have to research it more.  Never having encountered a Horsefly before, I was surprised to learn that although the males drink nectar, the females drink blood (usually from large mammals like livestock). She had scissor-like mouth parts that slice into the skin so she can get to the blood. This species is usually found along the east coast and Gulf of Mexico, so it was something of a surprise to find it here… assuming I got the ID correct.

We also got to see a male Red-Winged Blackbird flaring his epaulets at a female, and a pair of Brown-Headed Cowbirds performing what we thought was courtship behavior.  The two birds sat across from one another, then one ruffled its feathers, opened its wings a bit and bowed down at the other, and the other responded in kind.

Roxanne and I inferred the behavior was “courtship” but, from what I read, after I got home, what we were seeing was actually two males trying to outdo one another in a machismo contest.  Apparently, the females don’t respond well to the males’ bows, which they see as aggressive, so the males only bow to one another. (You can read more here.)  The males open their wings to one another, and to females, to show how mature they are. Juveniles have pale markings on the inside of the wings.

You can see the video snippet I took of the birds HERE.

And we found a couple of Black Phoebe nests, one stuffed full of babies who were almost fully fledged. They were stacked up, one on top of the other, with their tails sticking out over the edge of the nest. And toward the end of the auto tour route we came across a dead tree where there was a Western Meadowlark, a Red-Winged Blackbird and a tiny Song Sparrow all singing their respective songs.

We caught glimpses of American Goldfinches and Bullock’s Orioles, and hear Bitterns, but didn’t see any. One oddity was sighting a Mute Swan in the permanent wetlands area. That was odd because swans hardly ever go into the refuge, and Mute Swans are actually an invasive species. Unlike the Tundra Swans, the Mute Swans are super-aggressive and destroy the habitat they live in by ripping up water-plants from the roots.

When we were done at the Sacramento refuge, we decided to go over to the Colusa National Wildlife Refuge to show Roxanne the day-roost of the Black-Crowned Night Herons at the end of the auto-tour there. We were astonished to discover that the auto-tour there was roped off so no one could get to it… but the rope and signage was only visible AFTER you entered the refuge and started driving down the route. Stupid. They should have put the signs on the front gate or in the parking area.  A “manager” who showed up a little while after did, said that the auto-route was shut down because they were short handed and couldn’t patrol it well enough. Sad.

So, we didn’t do that tour and instead walked around a little bit in the native flower garden they have near the restroom facility.  Along part of a path near the garden, Roxanne found some galls we’d never seen before: the gall of the Elm Balloon-Gall Aphid, Eriosoma lanuginosum.

According to what I’ve read, the galls are initiated by a “fundatrix”, a parthenogenetic female aphid whose presence causes an extreme enlargement of the soft cell tissue on one side of the leaf. The galls are hollow and feel rubbery. They start out green and are covered with fine white hairs (which we saw) and turn brown as they age.

Inside the gall the fundatrix has her babies which are wingless and yellow until they mature. There can also be second generation aphids, called “alates” (usually winged individuals) which are dark green to black and wax powdered. Not all of the adults grow wings, however, and wing-growth seemed to be associated to crowding inside the galls, a short supply of food, and/or changes in the environment. Nature is so cool!

After walking around a bit, we headed back home to Sacramento and got there around 3:00 pm.
