Safari West

April 15, 2022
9:30 to 13:30

Today, I took Vertebrate Biology on our annual visit to Safari West, and it was fantastic as usual! In addition to the collection animals, I saw a respectable amount of native wildlife, as well. In this post, I’ll focus first on the wildlife, and at the end I’ll share some of my favorite photos of captive animals.

Fairfield Osborn Preserve

4/1/2022
10:00 – 13:00
Distance traveled: 1.5 km

Today, I took my Vertebrate Biology students up to the university’s Fairfield Osborn Preserve to survey part of the preserve’s network of coverboards, and to explore the creek with SSU alumna Julie Wittmann, who is now the Community Naturalist Program Coordinator for the preserve. The coverboards weren’t particularly productive, but by the end of our visit, I don’t think anyone left disappointed.

Sears Point Trail

March 28, 2022
09:30 to 11:30

Today, the Sonoma Land Trust hosted my Restoration Ecology class in a field trip to view the various phases of salt marsh restoration at Sears Point. It was a gorgeous day, and we learned a lot about the history and ecology of this place as we walked to the end of the levee and back. I another little surprise: one of our trip leaders, Neal Ramus, was an undergrad at SSU at same time I was, and it was good to reconnect.

Ellis Creek, Petaluma

March 4, 2022
09:30 to 11:30

This Vertebrate Biology field trip was designed to expose students to some of the basics of birding, and get experience identifying some common local bird species. We arrived at 9:30 a.m. to find the weather overcast (but not quite raining),and some landscapers using noisy equipment near the ponds. We spent about two hours walking the paths around some of the ponds, a total distance of 1.5 km.

Great Horned Owl (Bubo virginianus)
Procreate

For many years, a large Great Horned Owl lived in the eucalyptus tree in the empty field across the street from the house where I grew up. Although I often played in that field, and even climbed that tree, I didn’t see the owl very often, although there were a number of occasions where I did, including at least two times on Halloween. On this particular Halloween (1971 or 72), I was trick-or-treating with some neighborhood children when the owl flew down right in front of us, and landed in the middle of the Holzer’s front yard. How could I forget an event like that! One of my earliest “birding” experiences, and one which definitely made an impact on my young psyche, probably predisposing me to my current fascination with birds.
