The Naturalist Course is at Class 8 of 10, 03-29-19

We’re already in week 8 of the 10-week Certified California Naturalist course. Wow!  Next week is the final exam, and the week after that is graduation. Seems like the time just flew by!

The speaker today was Christy Berger who did a presentation on Crows and Other Corvids.  She’s with the Heron and Egret Rescue but has a live rescued crow and does speaking engagements on corvids throughout the area, so we’re having her do her crow thing today and then come back for the summer class to talk about the herons and egrets (because that’s when those birds are nesting and having babies.) she brought her crow Onyx with her. Onyx has an eye condition he’s had since birth so there’s a white film over his eyes all the time, and he’s very sensitive to different kinds of light. Christy gave her talk with a PowerPoint presentation, then had us turn on the room lights and turn off the projector before she brought Onyx out for us to see.  He spent most of the time trying to get his jesses off. Hah!

Christy’s talk focused mostly on crows and ravens, but also included a smattering of facts about different kinds of native corvids such as the endemic Yellow-Billed Magpie and California Scrub Jay.  She talked for about 2 hours, and then the class took a break.

When everyone came back from the break three of the students presented their capstone projects. Michele Sheehan did one on the interpretive signs she created for the Heather Farm Park in Walnut Creek, CA.  Then Fran Bowman did a presentation on the upgrade of an exhibit she’s doing for the Cache Creek Nature Preserve. They have a mastodon fossil (part of a pelvis and a tusk) and she’s updating the interpretive information on it.  Lastly, Rebecca Rubio-Aliaga did a presentation on the monitoring of Bluebird Boxes she’s doing for Napa-Solano Audubon… They were incredible.  I am so proud of the work they’re doing outside of class!

We also took a moment to thank Roxanne (who had brought candy, grapes and mandarin oranges to share with the class) for all the help she’s given us during the classes and field trips.  We gave her the plaque I’d made and a small felted fox.  She was very touched by the gesture.

Then Bill did his presentation on the last chapter of our textbook, one on “Energy and Global Environmental Issues”. We call it the “sad chapter” because it talks about all of the yucky stuff the environment has to deal with: air and water pollution, fragmentation, fracking, habitat degradation, neo-nic and Round-Up poisons, etc. Bill tried to rush through, hoping we’d get in some species ID time, but he finished right at 4:00 pm. Class over.  As I mentioned, next week is the final exam and the week after that is graduation. The students all decided they’d like to do a potluck for that day, so that should be fun!  #CalNat

A New CalNat Course is Finally in the Works

I finally got word from the board president at Tuleyome that they have approved my going forward with piloting a Certified California Naturalist (CalNat) course for them!  Woot!  I’ve been wanting to do this for about 2 years now.

The board president wrote: “…Last night the board unanimously decided to move forward with the naturalist program…  There was agreement that is would be great for the organization, both now and after the nature center is completed in Woodland, that it would be good for the organization as being seen as a leader in naturalist training, and that is would be good for you in your enjoyment and enthusiasm for your job!”

Another board member chimed in with: “…The Board approved in moving forward in concept… Great!  Cheers…”

I’m so excited to be finally moving forward on this.

Bats and Herps at my Naturalist Class

Tonight we had two critter lectures, went out into the field for about an hour, and then had another hour of general lecture, so it was a busy night.  We heard first from Sam Bachinni who’s a self-taught herpetologist (snakes, reptiles, etc.) and botanist.  He showed us photos and told us about the different kinds of reptiles, amphibians, turtles and tortoises we could find in the surrounding area.  I now have a whole checklist of new critters I want to go searching for, hah!  He told us that the best time to go look for amphibians, for example, is in the winter and spring months before it gets too hot, in areas where there’s fresh water that doesn’t have a lot of fish in it… And for the best viewing go out on full moon mornings because that’s when the Tiger Salamanders are out and about.  Get up above 800 feet in elevations, too, or pickings are slim. Now, see, THAT’S the kind of information I need!

Sam also said that the easiest way to tell a turtle from a tortoise is to look at its hind legs.  Tortoises have “elephant legs” in the back – short stumpy legs with a flat bottom – whereas turtles have more splayed feet that turn out to the sides.  I didn’t know what.

When Sam was finished with his presentation, we heard from Dan Neil.  He’s a bat expert, who is also into wild flower identification, insects and mycology.  He was a far more engaging and interesting speaker than Sam, but was pressed for time – our instructor John wanted to get us out into the field, and Sam had talked a bit longer than expected – so he whizzed through his presentation.  His talk included information on “megabats” (large bats, like fruitbats, that have small ears, large eyes, and don’t use echolocation) and “microbats” (which are the small ones we most often think of as classic bats with large ears that do use echolocation..  The bats most commonly found in our region include: Big Brown Bats (which have a lot of complex vocalizations), Great Mastiff Bats (who’s echolocation sonar is actually audible to human ears…”chip, chip, chip!”), Pallid Bats (light colored guys that roost in crevices), Hoary Bats (large furry bats with silver tips that are usually solitary and like to hang out in foliage), Western Red Bats (that look like winged pug dogs and live in riparian habitat), Mexican Free-Tailed Bats (that live in huge colonies under the Yolo Bypass and under the franklin Road bridge; their tails aren’t connected to their wings by webbing like most other bats), and Canyon Bats (that look like Siamese cats: blonde body and a black face).  More critters to add to me “I want to see these” list!

Things to look for when you’re searching for bats, Neil says, (besides guano) are urine stains on trees or buildings/construction and “pissicles” (really, that’s what they’re called) which are stalactites of crystalized urine.  Also look for “exfoliating trees”, trees where the bark is loose and shedding off, because bats like to climb in under the bark to roost.  When we went out into the field after the talks, we found several exfoliating trees on the nature preserve grounds, and checked out one of their bat boxes… no bats, though.  Sam said the best way to tell birds from bats in the low-light of dusk and dawn is that bats flaps their wings constantly and birds flap-and-glide.  “If it’s gliding, it’s not a bat.”  Good to know.

As an aside, I have the opportunity to go to a bat rehabilitation training in Placer County on June 6th.  Even though I don’t have any experience in it – and can’t handle the bats because I don’t have a pre-exposure rabies vaccination – I think I’d like to go just for the learning experience.  It only costs $10 to attend, but it’s about a 2-hour drive one way to the rehab center.  I’ll have to think about, but it sounds like a kewl thing to watch.

Anyway, during our field exercise for the night, we also went to another small made-made pond on the preserve surrounded by rushes, grasses, sedges and other vegetation, and learned a children’s poem to help tell them apart:  Sedges have edges… Rushes are round… and grasses, like asses, have holes.  Hah-ha-ha-ha-ha! Along the route we also came across a large deer skeleton.  It still had some of the hide on it, but all of the meat and organs were gone.  I took a few photos, and some video of Sam speaking and our teacher John trying to see if there was an owl in a tree (there wasn’t.)  He also has an app on his cellphone with bird calls on it, and he held his phone up and played a Screech Owl call… and a dog in an adjacent yard started barking in response.  D’oh!

Then it was back to the nature center for a short lecture on producers, consumers, and decomposers in the animal kingdom before we headed home for the night.

Naturalist Class Tuesday, May 19th

I  left the office early today and headed out to my weekly Certified Naturalist class for the evening.  Tonight’s class was on Forests and Woodland Resources and the guest speaker was Zarah Wyly of the Sacramento Tree Foundation.  I’d met her previously at last year’s acorn-gathering class at the nature center.  She’s a funny and engaging speaker, as well as very knowledgeable, so it’s always nice to spend time listening to her.  She identified all of the species of trees and shrubs within an hour or so walking distance from the nature center, so it was a great learning experience for those of us who don’t know a lot about the regional trees.

Before the class, I scouted around a little bit and got photos and video of a California Ground Squirrel doing its “alert call” for several minutes, several White-Breasted Nuthatches flitting from tree to tree – sometimes in groups and it made me wonder if they were adults with fledglings –a Scrub Jay picking berries from an Elderberry bush, and what I think was a Purple Finch (more colorful than the House Finches I’ve seen) singing in another Elderberry bush.

During the field study part of the class, we also saw a variety of birds along the way, and some Cottontail Rabbits, and a California Alligator Lizard.  You know, those lizards that were all over southern California when we were kids?  Well, now they’re considered “rare”.  I didn’t know that – although I was suddenly aware of the fact that, yeah, I hadn’t seen any of them for decades.  I see the Western Fence Lizards everywhere (the “blue bellied” ones that do push-ups), but I haven’t seen an Alligator Lizard in… forever.  I got photos and some video of the instructor, John, sneaking up behind it so he could catch it and show it to us.  He got it on the first grab.

I learned that Interior Live Oaks are the only ones in California that stay evergreen… that the “sycamore trees” along the riverside are actually London Planetrees… that Cottonwood trees are “beaver candy” (they’re the first trees beavers go for when they move into an area)… and that there is this totally weird-looking hybrid oak close to the nature center.  (Zarah thinks it’s a cross between a Blue Oak and a Valley Oak.  She said, “It’s kind of on the Valley side of Blue.”

We also learned about “mast years” for acorns.  I had heard about them – they’re the years when the oak trees produce massive amounts of acorns – but I had no idea that the phenomenon was statewide.  That is, ALL of the oak trees all over the state synch up and ALL of them produce an over-abundance of acorns at the same time.  Then the mast year is followed by a year where there is a glut of mule deer, squirrels and mice; and the year after that there’s a massive glut of ticks everywhere; and the year after that there’s a massive population explosion of snakes…  Kewl, huh?

There was also a brief discussion about Oracle Oaks, which are a recognized species of hybrid oak, a cross between the Black Oak and the interior live oak… and there are individuals of these trees along the American River Parkway.  They’re more common further north though.  You can read more about them if you want at: http://sierrafoothillgarden.com/2010/11/06/discovering-and-identifying-the-oracle-oak/.

As an aside: we learned that the mating pair of coyotes had their pups several weeks ago, and the pups are now out on the preserve… but no one will say WHERE exactly because the nature center doesn’t want the public tracking the babies down and annoying (or harming) them.  Mama coyote had FIVE pups.  In the class, they passed around a photo one of the on-site naturalists had taken of them… All five of them huddled together, heads up, curious, looking straight at the camera.  A classic shot.  And those babies are soooo cute!

Oh, and the nature staff gathered four Monarch butterfly chrysalises from the small stand of showy milkweed they have out in the front of the nature center, and one of the butterflies matured yesterday, and they were able to release it…  So growing milkweed in your yard DOES work.  FEED those Monarchs!

Training Workshop in Coloma, Ca in July.

I got word that the next Northern California UC California Naturalist Program Instructor/Partner Workshops are going to be held in Placer County in July (about an hour or so from the house in Sacramento).  This is the next step in the process that Tuleyome needs to take to get the organization onboard to actually TEACH the naturalist classes.  I asked Sara if I could sign up for it and she said, sure!  So I’m booked for the workshops.  It’s a 2-day thing over a Tuesday and Wednesday, so I’ll drive up on Monday night, stay in Placerville and then go to the workshops from there.

The first day covers all the necessities of building and executing the classes, the volunteer portal, iNaturlaist, homework and capstone projects; the CalNat system and partnering organizations; how to put a teaching team together; a week-by-week walkthrough of the classes required; and then techniques to market the classes you set up.  The second day is a “play” day and includes a tour of the Marshall Gold Discovery State Historic Park and journaling in the field.  Should be interesting stuff!  These workshops come right on the heels of a 4-day weekend during which I’ll be going up to Mount Shasta for two days of dragonfly classes.  I should be thoroughly exhausted by the end of that week!
