An Overcast Day at the Preserve, 02-28-19

Date: Thursday, 02-28-19
Time: 7:30 am to 10:30 am
Location: Effie Yeaw Nature Center, 2850 San Lorenzo Way, Carmichael, CA 95608
Habitat: Oak Woodland and riparian boundary
Weather: Overcast, 43° to 46°

Narrative: I headed out to the Effie Yeaw Nature Preserve for my trail walking right after I fed the dog his breakfast. I arrived about 7:30 am and it was 43° at the river. The first thing I saw when I got into the preserve was a Red-Shouldered Hawk just sitting on the lawn. It hadn’t caught anything (that I could see) and stood there, looking around for a short while, so I was able to get some photos and a video snippet of it before it flew off into the trees.

CLICK HERE for the album of photos.

After going down the wooden steps onto the Bluff Trail, I caught sight of a Western Gray Squirrel running along the trail with a mouth full of grass and twigs, so I followed it… and found where it was constructing its “drey” (squirrel nest). Dreys are different from other squirrel nests because they’re formed on the outside of a tree or cavity and built where several branches come together. ((If the squirrel’s nest is inside a tree or cavity, it’s called a “den”.)) If it continues to build there, walkers should be able to get some good views of the squirrel and its babies.

Lots of deer were out, including several small herds of does and their yearling fawns. I hung around one group for a while just watching a doe grooming her fawn. They’re so tender with their babies; it’s so relaxing to watch them. I also came across a couple of bucks, into two younger ones who were sparring for a little while. One or two of the does seem to be showing their pregnancies already. ((The gestation period is 7 months long so around 203 days.))

At one point along the trail, I saw two odd shapes in the top of a bare-branched tree. Because the sky was overcast, looking up into the branches everything was backlit, so it took a while for me to figure out what I was looking at: a pair of Wood Ducks (a male and female) looking for a place to nest.

I also came across more fungi today than I did on my walk with my naturalist student the other day. Puffball fungus, mushrooms, Elfin Saddles, and three different kinds of jelly fungus, including the nicest specimen of Witches Butter I’ve ever seen. I found a nice specimen of Trametes betulina, a kind of fungus that looks like Turkey Tail fungus (Trametes versicolor), but it has gills! It’s sometimes called the Multicolored Gilled Polypore or Mazegill. This is the first time I’ve seen it live and in such wonderful color. (I usually see it in its later stages when it’s just a bunch of hard weird gills.) Very cool.

Because it was early and overcast and a weekday, I didn’t see a lot of people, but had short interactions with those I did see: got to talk to one lady about Black-Tailed Jackrabbits and another about jelly fungi.

I walked for about 3 hours and headed back home.

A Walk with My Naturalist Students, 02-18-19

Date: Monday, February 18, 2019
Time: 7:30 am to 11:30 am
Temperature: 31° to 53°
Weather: Sunny, clear, breezy, cool
Location: Effie Yeaw Nature Center, 2850 San Lorenzo Way, Carmichael, CA 95608
Lat/Log: 38.6174656, -121.3115716

Narrative:  This walk was an impromptu walk for the Tuleyome CalNat course which I led.  We had 16 people, along with my co-worker Nate, Eric Ross (a former Tuleyome naturalist graduate, who’s now working to become a docent at Effie Yeaw), Mary Messenger (a volunteer “trail walker” at Effie Yeaw) and about a dozen students. One of the students also brought along a friend to participate in the walk. It was good group.

The first thing we saw when we entered the preserve was a trio of Eastern Fox Squirrels doing a ménage à trois thing right out there in front of God and everybody. Everyone joked that during the walk we witnessed instances of fornication, urination, evacuation, and mastication. Hah!

We saw lots of different fungi, identified quite a few plants and trees, saw several species of birds, and saw a lot of Columbian Black-Tailed Deer, including does and several bucks (including a spike buck, split-prong buck with only one antler, and some 4- and 5-pointer bucks. We got to see one of the larger bucks performing the “Flehmen Sniff” while he followed after a female. CLICK HERE for an article I wrote about the bucks and the sniff. CLICK HERE for the full album of the photos I took today. (When I’m leading a hike, I take far fewer photos than when I’m walking alone, but I get more”people” shots in the mix.)

We walked for about 4 hours and covered about 2½ miles.
