Checking out the “Reverend Mother” tree, 07-31-20

I got up around 5:30 this morning and after giving Esteban his breakfast and letting him out for potty, I headed over to the William B. Pond Park along the American River to do a kind of recon on the galls there.

There are several oak trees on the manicured lawn that often provide an abundance of specimens, and then, of course, there’s what I call the “Reverend Mother” tree: a particular Valley Oak that I go to every year.  It sits at an intersection of different parts of the trail near the river, and sports a wide variety of galls throughout the late summer.  I wanted to see what was out there before I brought my friend Roxanne over there on a gall hunt; to make sure that there was something there to see.

The galls are still just starting to emerge, but I did see several different species, including a beautiful Rosette gall (on the Reverend Mother tree).

There were also a couple of oak apple galls that were oozing black goo.  I cut one open and found the wasp larva inside, but couldn’t see any indication of other insect that was causing the rot. So, I figured they had some kind of fungal infection.  I couldn’t find any information on that in my research yet, though, so I’m not sure.

The honeydew galls aren’t big enough or engorged enough to start dripping, but I did see some Yellow Jackets hanging around the tree, looking for them.

While I was checking out some Round Galls, I saw a tiny red nymph, shaped kind of like a cigar, with black coloring at both ends.  I was surprised that it was relatively easy to figure out it was the nymph of some kind of Tube-Tailed Trip.  (Thank you, BugGuide.net)  But I’m still not seeing the number of insects I’d expect to find in the summer by the water.  I only saw one damselfly, some kind of Dancer.

Oddly enough, I didn’t see or hear many birds along the river, either, but I did come across some California Quail and a Bewick’s Wren. 

I walked for about 3 hours and then headed back home.

Seeing with a naturalist’s eye: so much life among the leaves.

And the Galls are Showing Up at the EYNC, 07-29-20

Up at 5:30 this morning and out the door by 6:00 am to go with my friend and fellow naturalist Roxanne to the Effie Yeaw Nature Center. I’m starting my Trail Walker duties there again after several months off.  I still need a neon orange reflective vest to wear (it was due today) to look more “official”, and I’ll wear that next time.  I can also wear the khaki vest my naturalist students bought for me, but it’s heavier material and I think it’ll be too warm to wear in the summer months.  So, today, I was just in shirt-sleeves – no vest. 

It was about 61° when we got there, and warmed up quickly. The high today was around 100°.

Rox and I were most focused on finding galls, and checked out some of the Valley oaks, Blue oaks and Live Oak trees scattered around the preserve. It’s still a little bit early in the season, but we saw quite a few different species.  On the Blue oaks, we found some small specimens of Crystalline galls, Plate galls, Saucer galls, and Urchin galls.  On the Valley Oaks we found Red Cones, Fimbriate galls, a Yellow Wig, and Spiny Turbans. 

And I was really happy to find lots of the spiny first-generation galls of the wasp Callirhytis quercuspomiformis.  I hadn’t seen them there yet (since the trees were trimmed), and was so happy that they had re-established themselves.  When they’re new and bright green, they feel spongy, but as the galls age, they firm up and turn tannish-brown.

We saw a few deer, including a pair of bucks in their velvet: a four-pointer and a three-pointer. (The eye guards don’t count.)  When their antlers are growing, they’re very sensitive to touch, so there was no head-butting… just a deep long stare from the older buck telling the younger one to back off.            

Columbian Black-Tailed Deer, Odocoileus hemionus columbianus. Two bucks in their velvet.

Here’s an article I wrote about the deer and their antlers in July of last year.

We also saw a couple of females, one near the nature center and one out by the river. They were by themselves and we speculated that they were either young does that didn’t have fawns this year.  July is the fawning season at the preserve, but we didn’t see any babies during this trip.

When we were heading out of the preserve after about 3 hours, we came across Rachael,the volunteer coordinator, who was helping to woman the docent table outside of the nature center building with some of the other volunteers.  She told us that earlier that morning, some of the docents had seen “tiny baby” coyote pups along the River Trail at the preserve!  Oooooo, how cool! I’d love to be able to see those little guys. I’ll have to keep an eye out for them the next time I’m out there.

She also said that later this summer, the river front near the preserve will be re-groomed to provide more spawning space for salmon.  Last year similar work was done along the Sailor Bar portion of the river, and this year will be the Effie Yeaw area’s turn.  The refit and reconstruction of salmon-friendly habitat will include dredging and reforming some of the river bed, and laying down tons of gravel that’s of the right size and consistency for the salmons’ “redds” (nests).  If the gravel is too big or too little, the salmon won’t lay their eggs on it.  The work at Sailor Bar was first done in 2009 and during that year about 1000 redds were spotted in the area.  Last year, there were ZERO because the majority of the finer gravel had washed away.

It’ll be interesting to watch the work progress in the river near the Effie Yeaw Nature Center/Preserve, and fun to see if lots of salmon can be spotted from the shore in the fall and winter months.

A parting view. As we left, we saw several Rio Grande Wild Turkeys, Meleagris gallopavo intermedia, stopping to take a drink from the pond.

Two Spots in Woodland, 07-26-20

Up at 5:30 am and out the door with my friend Roxanne to head out to the city of Woodland by 6:00 am. It was about 61° already that early in the day, and it got up to 100° by the late afternoon.

We wanted to visit the East Regional Pond and Ibis Rookery in Woodland.  Both of them are just off Road 102, and pretty close to one another.  We’d let Greg Ira (the statewide director for the University of California’s Certified California Naturalist program) know we were coming, so he met us at the East Regional Pond after we stopped at Dutch Brothers for some much-needed coffee.  I’d never been to the pond before, so it was a fun first for me. 

The pond is a large water retention pond right across the street from the turn out to Farmer’s Central Road in the city of Woodland, CA. It’s surrounded on three sides by private property and protected nature areas. Because these areas are screened off by fences, you cannot walk all the way around the pond. There is a wide gravel trail, however, and three viewing platforms from which you can view and photograph wildlife. 

This time of year, there isn’t a lot of water in the pond, but I could definitely see the potential for future outings in the winter and spring when the rains come and the weather cools off. I really enjoyed being able to see the place.

We got to see Showy Egrets, Great Egrets, American Avocets, Black-Necked Stilts, Greater Yellowlegs, Spotted Sandpipers, White-Faced Ibises, pelicans and other birds.  Many of them were in the far side of the pond, but as we walked from one viewing platform to another a handful of them sort of followed us around. 

There were little cottontail rabbits bounding all over the place.  Sometimes we’d see two or three together, running this way and that, chasing each other, stopping to munch a little bit on the vegetation. They were constant conversation interrupters.

Desert Cottontail Rabbits, Sylvilagus audubonii

We also saw about four or five Pacific Pond Turtles in the shallows of one part of the pond. They were all poking their heads up above the surface.  And when they moved around, they left a trail of mud floating behind them in the water.

Although there were gnats and midges in the air, we didn’t encounter many insects, and saw only one or two dragonflies. But we did find a large Paper Wasp nest. These wasps are usually pretty mellow, so I was able to tilt the nest up to get some better photos of it.

Paper Wasp, European Paper Wasp, Polistes dominula

The queen builds all the first cells and rears all the first offspring by herself. After that, her daughters do all the work, and she just lays the eggs. In this nest, we could see that the larvae were developing in their cells at different stages, and that some of the cells had already been sealed off. Inside the sealed cells, the larvae pupate, and then emerge as adult wasps. Here is an article I wrote about them in 2017.

After about an hour or so, we headed over to the ibis rookery.  I was assuming there would be a lot of juveniles out there by now, and I was right. There were a handful of the ibises still sitting on eggs, but most of the nests had trilling, begging, head-bobbing youngsters in them.  With their striped bills, they’re very striking.            

We also saw some Coots paddling through the water with their own youngsters behind and around them.  I hope they won’t hate me for saying it, but I think their babies are the goofiest, funniest, ugliest little things I’ve ever seen.  “Ugly Baby Judges You.”  They’re partially bald with red faces and yellow pokey-out feathers are called “ornaments”. The more ornaments a baby has, the more attention and food she’ll get from the parents.  Bling matters, apparently. Here’s an article I wrote about them in 2018.

Back to Mather Lake, 07-24-20

Up at 5:00 am again, to head out to Mather Lake Regional Park at 6:00 with Roxanne. We wanted to check out the side of the lake opposite of where we were earlier in the week.  [[For some reason, my hair is doing this humorous pokey-out thing on one side of my head, so the left side looks “startled” and the right side looks “bored”. Hah!  I must have slept on it weird.]]

Not a ton of bird sightings today; mostly just the usual suspects.  We did catch a glimpse of some Belted Kingfishers when we first arrived, but they’re shy and moving very quickly, so getting a photo of one of them is really difficult.  We could HEAR they chattering on both sides of the lake, but couldn’t get into a position to see them clearly. 

A very bad photo of a Belted Kingfisher

There was one young Canada Goose fledgling that we spotted “doing yoga”, standing on one leg, on the lawn area.  It wasn’t until it moved that we realized it was missing a foot.  Everything below the knee was gone on one leg, so when the bird walked it had a very bad very distinct limp.  I presumed that it may have gotten its leg tangled in fishing line which eventually amputated the bottom part of the leg, but there’s no way to be sure.  It must have had that injury happen very early, when it was still a gosling, because the stumpy leg seemed totally healed, and the bird had seemingly adapted well to its “defect”.

Crippled Canada Goose fledgling

We were surprised to see a hawk flying around where we were looking at galls.  It was being harassed by small birds, and took sanctuary among the leaves of the trees, but always kept itself just out of sight, so we never got a really clear view of it.  By the mottling on the chest, I assumed it was a young bird, maybe a juvenile Cooper’s Hawk or Merlin, but the head just didn’t look right. I loaded the sighting into iNaturalist, and it came up as possibly a Sharp-Shined Hawk, but I’m not sure.  Let’s see if anyone can give me a better ID.

Cooper’s or Sharp-Shinned?

We saw quite a few galls on the oak trees (and willow trees), but most of them are still in their early development stages so they’re not very large yet.  In another two weeks or so, they should be out and looking quite beautiful.  I think we saw about 20 different species, which was great. 

Among them, we saw some unusually huge examples of the round, spiny first generation Live Oak Gall Wasp galls. I was happy to see them because I hadn’t seen ANY yet this year and was worried they weren’t going to make it out. These first generation galls contain a dozen or more parthenogenetic female larvae that reproduce asexually.  (The second generation has it’s own special gall and contains both male and female larvae that reproduce sexually.)

Live Oak Gall Wasp, 1st Generation, Callirhytis quercuspomiformis. This specimen was huge and could have contained 20 or more larvae.

On the Live Oak trees there seemed to be a LOT of acorns this year.  We also found one example of “drippy nut”, an acorn that was oozing clear sticky discharged caused by a bacteria called Brenneria quercina.  It gets into the acorn when the acorn is pieced by the ovipositor of a wasp or otherwise breached (by some other bug or a bird pecking into it).  The exudation is super-sticky. I got a little of it on my thumb and it took almost an hour to work it off of my skin.

Drippy Nut, Brenneria quercina, AKA Lonsdalea quercina [a bacterium that infects wounds in oak tissue/acorns]

As we were leaving, we spotted some juvenile California Ground Squirrels.  Some were playing, and one was digging in the dirt. As we watched the one that was digging, we saw it lift a large flat rock with its mouth and moved it out of the way so it could get at whatever underneath it.  I got a video snippet of that one.
