Warm Springs Fish Hatchery, Vertebrate Biology

February 24, 2023
10:00 – 12:30 
40° F, foggy, overcast, and snow on the ground (later, rain)

My Vertebrate Biology students and I had a wonderful tour of the Warm Spring Fish Hatchery, led by Bryan Freele. We were able to see the operations inside and out, from when a fish enters the hatchery, through the process of fertilization and raising the fry, until they’re just about ready to be released.

Vertebrate Biology visit to Ellis Creek

February 17, 2023
9:30 a.m. to 12:00 p.m.

Our first off-campus trip of the semester was a visit to the Ellis Creek Water Treatment Facility in Petaluma. My students (I think 18 of them were in attendance) met me in the parking lot at 9:30 a.m., and spent about 2.5 hours walking the trails around the finishing ponds (total distance traveled: 2.6 km). The weather was clear and cool (but not cold). By the time we’d done about half of our hike, it was too warm for the fleece jacket I’d put on earlier in the day.

We had an amazing day, with a total of 47 species across all observers (although I didn’t personally see all of them; I saw or heard 43 species). Below are my own observations for the day.

Vertebrate Biology Campus Walk

February 10, 2023
11:30 to 12:45, sunny and cool

I took my Vertebrate Biology students on a brief (45-minute) campus walk before lunch, to practice our spotting and identification skills. We left out of the western end of Darwin Hall, and walked north, past Carson Hall to Copeland Creek. Along the way, lots of birds were seen and heard, including Northern Raven, Anna’s Hummingbird, American Robin and California Towhee. At least one Western Gray Squirrel was hanging around the lawn and trees south of the Art Building.

2022 Species Accounts: Non-Avian

Amphibians and Reptiles

Western Pond Turtle
Actinemys marmorata

  • 3/11: Sonoma State University. Several were seen in the water, and basking on the edges of the Commencement Lake.
  • 5/2: San Geronimo Creek, Marin County. This was the most exciting moment of the day. Right as we were returning to the vans to head home from Roy’s Riffles, some students found a tiny baby western pond turtle on the path. It must have just emerged from its nest, and was heading to the pond for the first time. OMG SO CUTE AND TINY! I’d forgotten just how small they are. The students who were able to see the turtle absolutely LOVED it (and so did I). I think it’s also spectacularly good news that this relatively young restoration site has nesting pond turtles. I’m not sure everyone else understood quite how exciting this is. (Although me kind of literally squealing about it might have been a clue).
  • 5/20: Sonoma State Vertebrate Biology BioBlitz

Steller’s Jay

Done during a Drawtober challenge, to the prompt “Camping.” Steller’s Jays always remind me of the field work I did throughout grad school. I spent most of every June camping near my field site, and most mornings I was awoken by the dulcet cries of these birds in the tree just above my tent.

Tidepooling at Campbell Cove

June 2 and 3, 2022
06:30

While staying at the Bodega Marine Laboratory for a workshop, and knowing that low tide would happen around 8 in the morning, a group of us decided to wake up early enough to do some tidepooling before breakfast. Well worth the effort. Campbell Cove was just a couple minutes’ drive from the dorms, and we arrived just after 6:30 to find a large expanse of beach exposed, along with the rocks that form the jetty.

Vertebrate Biology BioBlitz!

May 20, 2022
09:00 to 11:30

In lieu of a final exam on the last day of the semester, I host a BioBlitz on campus for my Vertebrate Biology class. On this day, we spent 90 minutes on campus identifying as many species as possible, and then went back to the classroom to formalize our lists. The students are able to work in teams of up to 3 people, and all teams are competing not just against one another, but also against me, using a point system to determine the score. We can use any and all identification guides, and both visual and auditory identifications are acceptable.

Desert Tortoise Sanctuary

May 15, 2022
12:30 to 2:00 p.m.

On the way home from Zzyzx, the folks in my van decided to make a stop part of the way home, to see if we could find some desert tortoises at the sanctuary in California City. It was a bit of a drive off the highway that took us away from anything resembling civilization. When we arrived at the preserve, the facilities consisted of two trailers (one for the naturalist, and the other was the giftshop). The naturalist was super friendly, and eager to give us some tips about where we might be able to find tortoises (although she hadn’t seen one in the recent past). It was quite warm – probably around 100° F – so we covered up and stocked up on water, and headed out into the desert landscape.

Desert Studies Center Pitfall Traps

May 15, 2022
07:00

Our last morning in the desert, several of us got up early to check a series of pitfall traps that had been set the night before. A few very cool animals found their way into the traps, and we were able to get some great photos before releasing them to go on their way. The traps were set up in transects, and I think we ended up checking 40 or 50 traps. Most of them were empty, but here are the things that we did see.
