Blue Oak Galls and Other Stuff, 07-09-19

I headed out to the Effie Yeaw Nature Preserve.  It was about 56° when I got there, but it was up to around 75° when I left.  When I got there, I was happy to see my friend and fellow-naturalist Roxanne there, too. She’s helping me out with the Monarch monitoring facet of my volunteer work at the preserve. I really appreciate her help, too, because it makes the somewhat tedious process of looking over each milkweed plant go more quickly. 

Still no sign of Monarch eggs or caterpillars, and what was odd was we didn’t see much in the way of other insects either.  We did find some spiders (including a White Crab Spider and a little Jumping Spider), some aphids, a single praying mantis, and a couple of beetles but that was it.  The lack of critters was rather surprising and made me wonder if the area had been sprayed or something.  We worked on the plants for about 90 minutes and then went for a short walk through the preserve.

 Although we heard a lot of different birds, we didn’t see any Wild Turkeys today, which was very unusual. They’re normally all over the place. We came across two bucks but no does and no fawns. Both bucks were in their velvet.  One was a nervous youngster who was just getting his first antlers (a “spike buck”), and the other was a laid-back 3-pointer who was just lying in the grass on the side of the trail.  He kept an eye on us but didn’t move from his spot. I guess he figured we were no match for him, so we weren’t much of a threat.  He was gorgeous. And because he was so still, we were able to get quite a few good photos of him.

The most exciting thing to me that we came across on our walk was sighting a few different species on a Blue Oak tree (Quercus douglasii) along the River Trail.  It had both Saucer Galls (Andricus gigas) and newly budding Crystalline Galls (Andricus crystallinus). The saucers start out flat and then form cups (some with smooth edges and some with serrated edges). The Crystalline Galls start out like tiny dark-pink urns and then swell up and get their sparkly spines. We hadn’t seen any galls at all on the “Frankenstein” hybrid tree further up the trail, so finding the galls on the Blue Oak by the river was rewarding. 

It was nice to see that this particular Blue Oak was also getting acorns on it. These oaks don’t produce acorns in drought years, and when they do produce acorns, they’ll produce a lot one year (a “mast” year) and then produce far fewer for the next two or three years.  So, as I said, it was nice to see this one with acorns all over it.  (The acorns usually take a year to develop.) Blue Oaks are also endemic to California, which means they’re found here and nowhere else on the planet.  It’s also one of the oak trees that is immune to the fungus that causes Sudden Oak Death.  Very cool trees.

Oh, and we found a Treehopper – but it jumped away before I could get a photo of it.  Those things are sooooooo weird-looking with their hunched backs. The one we saw was a Buffalo Treehopper (Stictocephala bisonia): mostly green with some burnished gold edges on it.

We walked the trails for about 2 hours.

Poults and a Snake, 07-04-19

Happy 4th of July.  Up at 5:30 am, and out the door before 6:00 to go to the American River Bend Park for a walk.  It was about 59°when I got there with a slight breeze blowing, so it was nice.  I was expecting the place to be crawling with people for the holiday, but nope. I had the trails almost to myself all the while I was out there. 

The very first thing I saw when I drove in was a doe crossing the road in front of me.  She stopped and looked behind her, and then I saw her fawn come out after her and scurry across the road, too.  I tried to get photos, but I had to shoot through the windshield so… nuthin’.  Dang it!  But the park was otherwise pretty kind, giving me two other surprises with better photo ops.

CLICK HERE to see the full album of photos.

The first of those two was getting the chance to see some Rio Grande Wild Turkey poults (Meleagris gallopavo intermedia). I hardly ever get to see them because the moms are so good at keeping them hidden. This was a group of three adults and five poults. The poults were all fledged in their first feathers but still too small to fly.  Among the adults was the leucistic (black and white) female I see often in the park. She was following after the other two, so I inferred that she was “learning” from them. She mimicked a lot of what they did, and also seemed to be helping out with protecting the babies.

At one point, one of the adults jumped up into an elderberry bush and started pulling berries off and dropping them to the ground so the babies could get them. A few seconds later, one of the poults got up into the bush, as well, but couldn’t reach the berries and jumped down again. So cute.  I think that little guy was blind on one side. It kept on eye shut all the time, and the lid looked “flat” in the socket (instead of rounded out by an eyeball).

I walked with the small flock for a while, but the adults were really good about keeping the kids out of the sunlight, for the most part, and keeping themselves between the babies and me. Who says turkeys are stupid?

The second surprise came when I walked down near the shore of the American River because there was a Buttonbush down there in full bloom and I think the flowers are so cool-looking. Anyway, while I was taking pictures of the flowers, I caught a glimpse of something moving past my foot and going behind me, so I turned around and saw a spotted snaky form slipping through the rocks.  At first I thought it was a gopher snake because they’re really common in the park, but then I caught a glimpse of the head. Not a gopher snake.

It was a young RATTLESNAKE. It was about as long as my forearm, so not too-too big, but still large enough to pack a good supply of venom. What was weird was: when I first saw it, it was in diffused light so all of the light parts on it looked pale blue and all of the spots on it looked kind of orangey. Very odd.

I followed after it a little bit to try to get more photos — which is hard for me on the shore because it’s all rocks there and my feet don’t work well on unstable cobbly ground.  I stopped when the snake got pissed off at me and wound itself into a striking position. Uh, yikes! I took just a few more photos and then let it be.

I also came across a small family of crows: a parent and two fledglings, I think. I saw the parent hand off a rock to the kids – which they weren’t interested in — and then pick up some seeds from along the shore.  The fledglings were very loud and fussy, demanding that mom feed them (even though they were large enough to fly and forage by themselves.) Huge mouths!  They cracked me up.            

Walking through the rocks on the shore, and then having to climb back up an incline to get to the trail pretty much did me in, though. The bones in my feet are “welding together” like Mom’s did from arthritis, so my feet don’t bend and flex like they should, which is why walking on uneven ground is hard for me these days.  Still, I was able to walk for about three hours total before heading back to the house.

Lots of Critters… and a Beaver, 06-20-19

Up at 5:00 am again. I let the dog out to go potty and fed him his breakfast then headed over to the Effie Yeaw Nature Preserve for my weekly volunteer Trail-Walking gig.  It was a gorgeous 58° when I got to the preserve and was overcast, so it never got over about 68° while I was there.  Perfect walking weather.

CLICK HERE for the full album of photos.

One of the first things I saw was a Red-Shouldered Hawk carrying nesting materials. First she flew over my head, then she landed on a tree to get a better grip on the grasses she was holding before taking off again. These hawks only have one brood a year, but often work on the nest throughout the year to keep it clean.  It’s no uncommon for them to use the same nest over several season if the first nest is successful.  Later in my walk, I went by where I knew one of the hawks’ nest was and found a juvenile (fledgling) sitting out beside it squawking for its parents to come feed it. It was capable of feeding itself, but some of these young’uns milk the I’m-just-a-baby thing for quite a while. While it was near the nest, it was hard to get photos of it because it was backlit, but later it flew out and I was able to get a few better photos of it when it landed in a nearby tree.

There were a lot of deer out today, but I didn’t see any fawns. I DID see a couple of bucks, though, both of them still in their velvet, a 2-pointer and one with wonky antlers (one super-long one and one stumpy one). The 2-pointer was walking with a doe, and when I stood on the trail to take photos of them, he decided he didn’t like that.  He stepped right out toward me with a very determined look on his face. (Bucks can get real possessive of “their” does.) I knew he wouldn’t rush me and try to gore me because he was still in his velvet.  In that state, the antlers are super-sensitive to touch, and if he rammed me, he’d actually hurt himself.  But, he could still outrun me mash me with his hooves if he had a mind to, so I put my head down and back away.  That seemed to be enough of a submissive posture to him, and he returned to his doe.  As beautiful as the deer are, I have to remind myself that they’re still wild animals and will do whatever their instincts tell them to do – even in a nature park.

I heard and caught glimpses of several Nuttall’s Woodpeckers on my walk, but never got enough of a look at one to take its picture. Those birds enjoy teasing people, I swear. They’re really loud about announcing themselves in flight, but then hide from you once they land.

The wild plum and elderberry bushes are all getting their ripened fruit now. I saw birds eating some of the berries and came across an Eastern Fox Squirrel breakfasting on the plums.

Along the river, there was a small flock of Canada Geese feeding (bottoms-up in the shallow water) with a female Common Merganser fishing among them. They eat different things, so the geese were stirring up the water plants and the Merganser would grab any small fish that appeared. Unintentional mutualism.  While I was watching them, I saw something else in the water, swimming against the current and realized it was a beaver! 

I went down as close to the shore as I could – (It’s hard for me to clamber over the rocks.) – and tried to get some photos of it. Photo-taking was difficult because the beaver stayed close to shore and was obscured by the tules and other riverside plants and scrubby trees. When it got into less cluttered spots, in was in the shade, and my camera had trouble focusing between the dark and the reflections on the water.  So, I walked ahead of where I thought the beaver was heading to a sunnier spot and waited for it… and waited for it… and then I heard a splash and realized it had swum under the water right past me and came up in the river behind me.  Hah!  Sneaky Pete!  

I walked for about 4 hours and then headed back home.
