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.

Lots of Fledglings and Other Critters Today, 06-30-19

I got up around 5:30 this morning and immediately headed out to the Effie Yeaw Nature Preserve for my weekly volunteer trail walking thing.  It was cool, around 55°, when I got there, but as soon as the sun got up a little higher in the sky it started to heat up.  It ended up around 75° by the time I left the preserve.  There were some latent clouds overhead which meant it was humid, too. Not my favorite.

Along with the usual suspects – deer, Acorn Woodpeckers and Wild Turkeys – I got to see quite a few fledgling birds out today.  The fledglings are fully feathered and the same size as the adults, but not quite adept at flying yet, so they spend a lot of time around ground level begging their parents to feed them.  They’re so bossy!  I watched one little House Wren fledgling sitting on top of a pile of old tree limbs.  For a while, he tried posturing like the adults do with his little tail standing straight up behind him, but then he got tired and just sat and dozed… until he saw or heard one of his parents flying by. Then he’d perk up and open his mouth wide expecting food to be dropped into it. Hah!  Although I could see the parents flitting around where he was, they also had other fledglings in the nearby shrubbery (which I could hear buzzing away), and because I was standing between the shrubs and the baby on the woodpile, they wouldn’t go near him. After getting quite a few photos of the little guy, I decided I’d better move on or he wouldn’t get fed at all.

I also came across two fledgling California Towhees.  Now, the California Towhees usually look kind of obese and drab to me, but the babies… they were soooo scrabbly looking; total bed-heads!  They were sitting close to one another with their feathers all fluffed out, so they looked extra fat and messy. Made me chuckle.  One was content to sit and wait for their parents to bring breakfast, but the other one was extra hungry, I guess, and kept tugging at the dead grass near them trying to get something out of it. Can’t get milk out of a stick, son. Sorry.

Further on along the trail I could hear a parent and fledgling Red-Shouldered Hawk calling to one another.  The fledgling was very loud and persistent, demanding to be fed, and the parent would call back him as if to say, “Shut up! I’m working on it!”  I eventually came across the fledgling sitting up in the bare branches of a tree. (He was so loud he was announcing to everyone exactly where he was.)  He saw me and tried to scramble away to other branches but was still unsure of how to make his wings work, so he looked pretty clumsy.  He stuck to the shadows as much as he could then, but I was still able to get a few photos of him.  (And I’m assuming he was a male based on his coloring; females are usually larger and have less vivid colors.) 

I also found one of the parents, sitting quietly now in the low branches of another tree right along the side of the trail, just above eye-level, ignoring the fledgling. Totally habituated to people, it didn’t move from its perch, but kept its eye on me as a passed by and stopped to take some photos. I think they’re such handsome birds.

CLICK HERE for the full album of photos.

Among the other things I found today were a few Pumpkin Galls on the leaves of a Live Oak tree. It’s kind of early in the season for those, so I was surprised to see them.  They’re super-tiny galls, and if you don’t know where or how they develop you’d completely miss them. Right now, they’re pale green, but come fall they’ll turn dark orange and fall off the leaves onto the ground were the little larvae will pupate through the winter.

I found a few Eastern Fox Squirrels and some California Ground Squirrels.  I was surprised to see one of the Fox Squirrels climbing through poison oak and eating the berries! Yikes!  I mean, I knew that the toxin in poison oak don’t generally harm wildlife, but I’d never actually seen any of the animals eating the stuff before.  I also saw a Fox Squirrel eating the husk off of a black walnut and watched a Ground Squirrel eating the tops off of some other plants.  (I think that gal was blind on one side, but once she saw me she moved too fact for me to get photos of her blind side.)

The other cool thing I spotted along the trail was that feral honeybees have found the tree along the Pond Trail again and seem to be setting up house there.  I saw them last year (I think it was) checking out the big opening in the side of the tree, but they left the site after a few weeks.  I guess the queen didn’t like it.  Now the opening is more covered with plants, so maybe it will feel more “protected” to them and they’ll stay there this time.  I let the gals in the nature center know they were there, so hopefully they can discourage hikers from walking off the trail to see the bees. We’ll see.

Only the Vulture Seemed Cooperative, 06-27-19

I got up around 5:00 am, let the dog out to go potty and fed him his breakfast. Then I headed over to the Effie Yeaw Nature Preserve for a walk.  I was joined by fellow volunteer trail walker, Mary Messenger (“The Other Mary”).  The weather today was beautiful, cool, breezy, sunny… in the 70’s. Just gorgeous.  I was able to keep the bedroom window open for most of the day to let the fresh air in.

At the preserve today the sightings were few and far between, and Nature was playing keep-away (we’d see something, but it was gone before we could get any decent photos of it). It took quite a while before we spotted a single deer, and I’m hoping that’s because a lot of the does are off having their babies right now.  Among the deer, I did see a couple of bucks in their velvet, including the one with the wonky antlers (long on one side, stunted on the other). 

And I came across a male Wild Turkey that I assumed was sick. It was hunkered down on the ground and breathing in short breaths, as though it might have been in pain.  It let me get to within touching distance of it and made no effort to get up or get moving.  My brain goes to the two most pervasive threats to the turkeys: rat poison and West Nile virus.  The turkeys in the preserve are surrounded by a huge residential area… and those nasty poison-pellets folks put out for rats look like food to the birds.  And we’re in the middle of the mosquito season, so West Nile can be a factor for many animals.  There’s no way to know what was affecting this papa, though, unless he can be caught and examined.

I took a photo of the turkey with some of the landscape markers so it would be easier to locate him at a later date/time if necessary.

According to the National Wild Turkey Federation, other things can also impact on Wild Turkeys, such as avian pox (which can result in the lesions in the esophagus and make breathing difficult for the birds) and several different kinds of equine encephalitis. (Usually, though, the birds are carriers of the equine diseases and don’t succumb to them themselves.)  Avian influenza and Mycoplasmosis can also be problematic, but they usually only affect domestic turkeys kept in small confined areas where they’re breathing each other’s crap for days on end. Poor babies. 

On a happier note, we did come across a very cooperative Turkey Vulture who was preening himself on the end of a large barren branch in a tree… and on that same branch was an Eastern Fox Squirrel preening, too.  So, we got quite a few photos of both of them.

The Other Mary had to cut her walk short because she had a lunch date with an old friend, but I kept walking for another hour or so after she left, so I put in about 4 hours of walking before heading home again.

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.

Lots of Nesting Birds, 04-30-19

I got up around 5:30 and was out the door by about 6:15 am to go to the Effie Yeaw Nature Preserve for my regular Tuesday trail-walking gig. The weather was beautiful: about 53° when I got to the preserve and about 70° when I left. Sunny and a little bit windy.

I saw LOTS of birds’ nests: European Starlings bringing some twigs for the nesting cavity and some bugs and worms for the hatchlings. (I could hear the babies squawking inside the tree); Phoebes bringing bugs for their babies; an Oak Titmouse carrying fecal sacs out of her nest; a male House Wren showing a nesting cavity to a female, even going to far as to get into the cavity himself, stick his head out and sing to her. Hah!

CLICK HERE for the album of photos.

Saw lots of squirrels, especially young Fox Squirrels who were running around, jumping, and putting just about everything they could into their mouths.  Generally, acting “squirrely”. Hah!

I found some caterpillars I’d never noticed before on the Redbud trees. They were pale green and had folded themselves inside the soft leaves of the tree.  You’ll never guess what they’re called…  Redbud Leaf-folder Moth caterpillars. Sometimes the names are like, “Duh!”, obvious.

I also found caterpillars on the leaves of the blackberry bushes, and these guys were tricky. They had an escape hatch, so if I touched the front of their silk “nest”, they would zip out the back and fall onto the leaf below them. Some of them had black faces and some of them had reddish-tan faces. I haven’t really ID-ed them yet.

And, of course, there were Tussock Moth caterpillars everywhere.  Here’s a video snippet of an active guy on the top of one of the water stanchions at the preserve: https://youtu.be/Bj9nZiy_EmI

I think I’d mentioned before about the fact that I was finding tiny dirt-clod turrets on the trail.  They look like “hoodoos”; y’know like the big stone ones at Bryce Canyon, but on a tiny-tiny scale.  I couldn’t figure out what was making them, so I put my naturalist students on the hunt for information. Naturalist graduate Deborah Dash sent me some photos of the Diadasia bees and the turrets they make, but all of the photos were from the top of the turrets not the side, so I couldn’t really compare them to the photos I had.  But, that tip led me to look up other Diadasia bees, and I think I found the right one.  I now believe these are the turrets of the “aggregate nests” of the solitary, native Mallow-Loving Digger Bee, Diadasia sp., subgenus Coquillettapis, This website shows how the turrets are created. So neat! (http://nathistoc.bio.uci.edu/hymenopt/Diadasia%20Coquillettapis.htm)

Near the end of my walk, I couldn’t understand why I was so frigging tired. Then I looked at the time and realized I’d been walking for FIVE HOURS!  Yikes!  I get so wrapped up in what I’m seeing on the trail that I lose track of time.

It was “Buggy” Out There Today, 04-27-19

I got up a little before 6:00 am and headed out to the Effie Yeaw Nature Preserve for a walk.  I wanted to get there by 6:30 so I could beat the heat for today.  Actually, the weather was rather pleasant all day, but anything over 70° is uncomfortable for me when I’m outside.

When I got there, The-Other-Mary, Mary Messenger, another volunteer trail-walker at Effie Yeaw, was there wanting to join me, and my friend/naturalist/volunteer Roxanne Moger also showed up. So, we had a nice time looking at all the little stuff that was around us.

CLICK HERE for the full album of photos.

Roxanne and I were more focused on bugs and galls this time around than the larger animals, so we were moving really slowly, investigating the leaves of plants and using the macro-settings on our cameras.  I actually like the quality of the macro-photos better on my cell phone than on my camera (it can get in tighter and more clearly), so I was using that a lot.  The best finds of the day were made by Roxanne who discovered a Tiger Swallowtail butterfly in a tree and a California Alligator Lizard hiding in some clover.  The alligator lizards are super-common in Southern California, but we don’t see them much here, so finding one is always fun.

We located a Black Phoebe nest, found out where an Oak titmouse was hiding out in a tree (that was guarded at the moment we saw it by a Western Fence Lizard), and also saw a Starling leave her nesting cavity with a white glob in her beak. She threw the glob down in a field and kept on flying.  I’m assuming she was doing housekeeping and tossed the babies’ fecal sacs.

We saw a few deer, including a pair of bucks in their velvet. One of the bucks decided to do a head-scratching maneuver that, at the same time, flashed his junk at us.  Hah!  How rude!  I also came across a doe who was having a sneezing fit.  I don’t know if she snuffled up something while she was browsing or what, but she was loud!

The elderberry bushes are just starting to flower-out, as are the Buckeye chestnut trees. The few plum trees in the preserve already have plums on them, and some were starting to turn purple.

On the walk, we came across both Oak Apple wasp galls and Live Oak wasp galls.  And, as for the insects, I saw Pipevine Swallowtail caterpillars and butterflies, Painted Lady caterpillars and butterflies, some Tussock Moth caterpillars, Craneflies, some bumble bees, hover flies, damselflies (including a male and female Pacific Forktail), Soldier Beetles, ladybugs, aphids and some Spittle Bug spit and other critters. There are so many teeny-tinies around.

By this time of the spring, some of the butterflies are already looking pretty ragged. I saw several of them with tears in their wings and frayed edges.  I think some of the damage is done by the grasses that grow up around the flowers and plants the butterflies utilize. The razor-edges of the grass can cut human skin, so I can only imagine how quickly they can damage the fragile wings of the butterflies.

I walked for about 4 hours and then headed home.
