The Cows Were More Obvious Today, 10-20-18

I had decided to just rest up over this weekend, but I couldn’t resist heading out to the Cosumnes River Preserve in the early morning. The preserve had posted that 90% of their wetland areas had water in them, so I wanted to see what it was like out there.

Uh. If what I saw out there was indeed 90%, then there are huge areas that the public can never see. The slough and some of the rice fields adjacent to the preserve were full of water, but there was no water in the wetland areas around the boardwalk or Desmond Road (which is where the public is allowed to do viewing). So, I was super disappointed as I felt the public had been lied to by the preserve.  Apparently, quite a few other people had also been duped by the announcement; there were cars cruising up and down Desmond and Bruceville Roads looking for birds.

The lack of water also meant a distinct lack of wildlife viewing. I did get to see COWS in some of the fields, and some Sandhill Cranes in other fields (but too far away for my camera to get any good shots of them). *Sigh* There was one Red-Tailed Hawk that was hunting near the boardwalk area and sat on the top of a short tree, so she could see what was around her. I saw her go to ground at one point, but don’t think she caught anything. The only other birds I saw were the common Canada Geese, Greater White-fronted Geese, Mallards, Brewer’s and Red-Winged Blackbirds, and some Bushtits and White-Crowned Sparrows. Nothing special.

I saw a few tiny damselflies that I think were Paiute Dancers, and also came across two large praying mantises, gravid females looking like they were ready to lay their eggs.

But overall, I felt the trip was a bust.

Nature Walk on a Lovely Day, 09-14-18

I went on a photo walk with my coworker, Nate, and one of Tuleyome’s donors/volunteers, Sami, to Lake Solano Park this morning.

The weather was extraordinarily lovely today. It was in the 50’s at the park and got up to about 75º by the late afternoon. There was slight breeze and the sky was filled with cirrus clouds. Gorgeous.

Sami is an avid birder – she logged 300 species last year! – and she was able to point out birds to us that we might have otherwise missed. Many of them – including a juvenile Golden Eagle – were on the fly and moving fast so I wasn’t able to get photos of them. But it was still cool to see them.

And Nate is a total nature nerd, like me, so it’s always fun to go out into the field with him. We get excited by things like bugs and fungus and otter scat… so, we enjoyed locating and identifying galls on the trees in the park, hah! We even found a gall I had never seen before. (Or at least didn’t recognize. It turned out to be an early stage of the Round Gall.)

The stand outs for the day for me, though, besides the lovely scenery at the park (which sits right along Putah Creek), were the peahens and their babies, a sleepy Western Screech Owl, a juvenile Great Blue Heron (who startled us by “appearing” on the shore right next to the path we were walking on), and an American White Pelican who was sitting in the middle of the creek, preening, sunning, and doing a little fishing.

We walked for about 3 hours, and then headed our separate ways.

Insects at the Wetlands, 09-09-18

I headed out to the Cosumnes River Preserve to see how things looked there.

On the way to the preserve, I counted 15 hawks along the highway (not including two that had been hit by cars), and that seemed to bode well, but at the preserve itself it’s still pretty bleak. They’re just now starting to pump water into the wetland areas, but today there was only a puddle at the far end of the boardwalk. Not enough to support many birds; and what birds were there flew off as soon as they saw me.

There is also no water along Desmond Road, so nothing to see there either. I DID get to see a handsome juvenile Red-Tailed Hawk along the also-empty slew. It had landed on the cracked and dried bed of the slough… but was then chased off by a very brave ground squirrel. The hawk flew up into the naked branches of a nearby tree, and I was able to get quite a few photos of it before it took off again.

Since there wasn’t much else to see, I pulled by focus in tighter and started combing the few surrounding trees and shrubs with my eyes for any sight of galls, insects and other stuff like that. It took a little time, but I was rewarded for my patience.

I found single specimens of three different species of dragonfly: Easter Forktail, Green Darner and Blue Dasher. All of them were in the trees, not moving, trying to warm themselves up in the morning sun. I also found several Praying Mantises (mostly boys and one girl), and a fat adult Katydid. I got some of them, including the Katydid, to walk on my hands. I also spotted some Trashline Spider webs but couldn’t see the spiders themselves.

Along the road I found a large bird’s nest that had fallen out of a tree, and, sadly, some road kill including an opossum and *waah! a Black-Tailed deer fawn. The fawn was smashed flat, so it must’ve been hit by a semi or something. I can’t imagine how traumatic that must have been to its mother. The fawn was a newborn, still in its spots…

As for the galls, I also found several different kinds: Spiny Turbans, Club Galls, Round Galls, Oak Apple galls, and every some “Woolybear” galls (Sphaeroteras trimaculosum). There were also the galls of the Ash Flower mite on an ash tree.

My sister Monica had asked what “galls” were specifically… Galls are malformations caused by the interaction between a plant and an insect (like a wasp or midge or mite), a plant and a fungus (like rust fungus), or a plant and another plant (like mistletoe). To protect itself from the insect, fungus or other plant, the host plant (or tree) forms a protective layer of material over the intruder, and that protective layer is the gall. Galls can be in the leaves, in the bark, on the branches, or on the flowers, seeds, catkins or acorns.

The Woolybear galls I saw today, for example, are formed on the backside of oak leaves when a cynipid wasp lays its egg on the leaf. A chemical in the egg tells the tree “grow something here”, and also gives it a blueprint of what to grow. So, what you’re seeing in the photos is actually fuzzy plant material that the oak tree grew to protect itself from the developing critter inside the egg. The wasp larva grows inside the gall and then exits when its mature. Each wasp species has its own unique gall (and some have two different ones in the same year).

Anyway… I walked for about 2 hours and then headed back home.
