Summer 2019 CalNat Class #6, 07-12-19

Around 11 o’clock, my co-instructor Bill Grabert and I took all of our stuff over to the library to set up for the Certified California Naturalist class, and our guest speaker arrived around the same time: Jenny Papka of Native Bird Connections.  She’d done a lecture for our winter class earlier this year so she kind of knew the drill. She set up her bird stuff while we finished setting up the classroom.

Jenny brought a Peregrine Falcon, a Swainson’s Hawk and her Eurasian Eagle Owl with her this time. Since she was ready to go when the students arrived, we just let her go first and did our announcements when she was finished. We also to a break when she was done, so the students could get photos of the owl and the props Jenny had brought with her.

 About halfway through Jenny’s presentation, our volunteer Roxanne Moger arrived with a box of bird’s nests she’d gotten from a retired teacher, and a HUGE live sphinx moth caterpillar in a jar. She’d been cutting down some grape vines for her neighbor and found the caterpillar on them.  Super cool.

It kind of looked like a tomato hornworm, but was gray instead of green and had a eye-spot on its rump. I’m not sure but I think it’s the caterpillar of an Achemon Sphinx Moth (Eumorpha achemon).  They’re the kind of caterpillar that pupates underground, though, so Roxanne will have to put a couple of inches of dirt in the bottom of the jar, so the caterpillar can bury itself when it’s ready.  It might overwinter under the dirt, so we may not be able to see it until next year…            

After the break, Bill did the chapter on forest management, and I did a module on bird species identification.

Summer 2019 CalNat Class #5, 07-05-19

Because it was a holiday weekend, only about half of the students in our Certified California Naturalist program showed up for this class, and we didn’t have a guest speaker.  So, it was a more “intimate” group, and we got to do a lot of species identification stuff and showed the students how to use the various facets of Calflora.org and CalScape.org for plant species identification.

This particular class focused on plants, so our volunteer/fellow naturalist Roxanne Moger, brought in her display of a variety of different seeds.  The students took time to go through them and tried to figure out the mechanism the plant might use to disperse its seeds.  

 Nate also helped to augment the class with a “spot the critters” exercise. He was showing the class images from the field cameras we have set up at the Silver Spur Ranch, and how he has to go through the photos carefully in order to see what’s actually being recorded. ((This is the project being funded in part by the grants I got from the Sacramento Zoo.))

Our 2nd Naturalist Class for the Summer, 06-14-19

Today’s class focused on collaboration and interpretation, data gathering, field journaling, how to record volunteer hours, and how to use online websites and cellphone apps to correctly identify species. Students were provided with practical learning opportunities by the class instructor, Bill Grabert, and our volunteer, Roxanne Moger.

Roxanne had brought in her collection of plant samples and seeds (which were gorgeously presented in clear boxes, some with magnifying boxes inside to show off the seeds). While the students signed into iNaturalist, Roxanne showed them how to identify the samples through the app.

Our guest speaker today was Our speaker, Nancy Ullrey, the Executive Director of the Cache Creek Conservancy.
