Naturalists at the Conaway Ranch, 03-10-19

I headed out to Woodland around 8:30 am to help my co-worker Bill with his recon outing at Conaway Ranch.  He has about twenty outings slated for that venue over the next months or two; he takes school children out there to tell them about food chains, rice growing and harvesting, wildlife, etc. There’s a slough that runs through one part of the property and it acts like a mini-riparian habitat that attracts otters, opossums, birds, snakes and small critters.  Today, he just really wanted to look at the state of the property after all of the rains and see what there was around to tell the kids about.

I was expecting some of our current naturalist students to join Bill out there, but instead, we had four of our former students (now certified naturalists themselves) come out –Susan Sallocks, Barbara Meierhenry, Bob Ream and Donna Moyer – all offering to help Bill with his future outings. All of them greeted me, some hugged me or wished me well in my ongoing fight against The Children of Wilson, and a couple of them said how much they had enjoyed the naturalist class and how I’d changed their lives for the better… It was all so unexpected and lovely, it almost made me cry. What a sweet way to begin our day.

We spent about three hours walking along the slough, checking out tracks, trying to identify the birds around and in the air overhead, looking at the different plant species starting to emerge everywhere.

The first thing I saw when I got to the spot was a medium sized garter snake curled up along the side of the road. It was limp and cold, and it wasn’t moving. But I couldn’t tell if it was truly dead or just in a deep torpor because it was so cold outside (in the high 40’s).  Its eyes were still clear, it didn’t look like any part of it had been run over by a car, and it was limp, not stiff with rigor mortis. I took some photos of it and then put it back down the way I’d found it. At the end of our walk, it was still there, so I guess it was dead. It’ll make a good meal for some critter.

Bill showed us some of the props he uses for the outings with the kids including one about the water cycle and how rice grows. Very cool and informative. We didn’t see any live crayfish, but we did find several skeletons and their mud chimneys in the burned rice field.

There was a team from the University out on the property checking on and upgrading the solar-powered electronic boxes on the Wood Duck boxes they have lined up along the slough. They stopped to talk with us for a little bit and then went on ahead of us.

As far as wildlife went, we didn’t see a whole lot, but did get to see crows, bullfrogs and Pacific Tree frogs, flocks of Greater White-Fronted Geese and Sandhill Cranes flying overhead, some Marsh Wrens, Red-Winged Blackbirds, Northern Mockingbirds, a Say’s Phoebe, and a Great-Horned Owl.  We heard a Belted Kingfisher but couldn’t see it. As the weather warms up, there will be a lot more to see there.

A Very Conspicuous Great-Tailed Grackle, 05-26-18

I got up at 5:00 today, even though it’s the weekend, because I wanted to get back to the Sacramento National Wildlife Refuge for a longer trip around the auto-tour there.  It was overcast and drizzling all morning, and the sun didn’t come out until just about when I was ready to leave the refuge.  I stopped off at the Colusa National Wildlife Refuge and spent about an hour there before heading onto the Sacramento refuge.

At the Colusa refuge, I was surprised to see a large flock of sheep near the front gate. Sheep and goats are often brought in to help clear the landscape of overgrowth and noxious weeds – because they eat anything. I saw several American Bitterns there, many of them on the ground among the tules. They were too far away to get really photos of them, but I managed to get a few so-so shots.

Most of the ground at the Colusa refuge are dry – no standing water – so it can be difficult to see much of anything.  I did get to see a lot of Great Egrets, Snowy Egrets and Great Blue Herons there, along with several crayfish chimneys, pheasants and a young Pied-Billed Grebe that was still sporting its striped face. The neatest sighting was that of a young coyote loping across the fields.

At the Sacramento refuge I was first inundated by sightings of Black-Tailed Jackrabbits, Desert Cottontails and California Ground Squirrels, and I thought that was all I was going to be able to see there today. Eventually, the place “opened up” to me and I was able to get photos of other critters, too. What was really nice was that I literally had the place all to myself. Didn’t see any other vehicles (besides the rangers’) until just before I was ready to leave. So, everything was nice and quiet, and I didn’t feel rushed.

Of the ground squirrels, I saw, I came across one that exhibited a behavior I’d never seen before. It raised itself up on its hind legs, into a standing position, and then rubbed its head and face against a twig. I don’t know if it was transferring scent or just had an itch (it looked a bit mangy), but it was neat to see.

At one point, I stopped because I saw something “odd” on one side of a slough. I couldn’t get a good look at it, even with the telephoto it was sitting on the bank closest to the road, among the tules, with its back toward me. I kept an eye on it, and eventually it dipped down into the water in the slough… a muskrat! It played “keep away” for quite a while, ducking under the surface of the water just as I got the camera focused on it. After a while I tried to anticipate where it might show up next and was rewarded with some video footage of it. Phew!

The other cool find of the day was seeing a male Great Tailed Grackle walking along the rails of a wooden fence.  It was calling and posturing all along the way. I got some video footage (so you can hear the sounds it made) and some fairly good still shots… and I got to see some male Ring-Necked Pheasants sitting a tree. I’d never seen them in tree before; I usually sot them on the ground. They’re large colorful birds, so when they’re up in a tree they’re very “exposed”. There must’ve been something on the ground that scared them.

When I stopped to get some photos of a large bullfrog in the water, I saw something else beside it that I couldn’t identify at the time. I took photos and video of it and when I got home, I looked at it over and over again trying to figure out what I was looking at. I finally decided it was a pair of freshwater snails or whelks laying eggs on a rock… So weird…

I left the refuge around noon and was back home around 2:00 pm.
