Lots of Behaviors – and Fawns, 07-30-19

I got up about 5:00 am this morning and immediately headed out to the Effie Yeaw Nature Preserve for my Monarch Larvae Monitoring Project and Trail Walking volunteer work. My friend and fellow naturalist, Roxanne, came along. It was about 60° when we got there and was around 77° when we left.  A relatively mild morning for summer, weatherwise.

I know it’s a productive trail walking day when I come home with over 1100 photos in my camera. So much to see today! 

Well, we didn’t see actually anything worth reporting on our milkweed plot (except that is smelled like something had urinated there), but on some of the plants in the other plots we found lots and lots of Green Lacewing eggs, a large spider, some Ladybeetles and lot of Oleander Aphids.  We also found a katydid nymph who was in her “teenage” instar.  Her wings weren’t fully developed yet, and she was missing a hopper leg, so she was kind of clumsy on the plant. 

We knew it was a female by its pronounced tan-colored ovipositor on the end of its abdomen.  The adult females lay eggs in rows, one stacked against the other and sort of glues them down onto rough twigs to secure them in place.  All of the katydids we’re seeing now will only live for the season and will probably all be dead by October, so they have to work fast.  And just a fun fact about these little critters: both the males and the females can make sounds with their wings and legs, and they “hear” through tympanic membranes in the knees of their front legs!

When we were working on the milkweed plants, we could hear the wild Turkeys “complaining” from a nearby hillside.  We never did figure out what they were fussing about, but we were able to get a few photos of them when they walked by.

Later on, we found a group of female turkeys scratching in the dirt and leaves under a tree, just like chickens do, looking for seeds and bugs.  And a little further along the trail, we also came across a group of males who were bullying one another.  One seemed to be taking a lot of crap from another one, and a third one would join in now and then to bite them on the heads.          

Major face wrestling. Sometimes they’d get their opponent’s whole head in their mouths. In this photo, both birds have their nictitating membranes shut over their eyes to protect them from getting scratched.  These are immature male Rio Grande Wild Turkey, Meleagris gallopavo intermedia

The two main competitors were “face-wrestling”, biting on another on the face or neck and wrapping their necks around one another, each one trying to get the other to submit.  We watched them for quite a while, and then a second pair started wrestling, too.  One hiker came by to watch with us for a little bit and take some video of them. 

When we left the turkeys to look for some galls, we could hear a hiker behind us yelling at the turkeys, “Hey, break it up, you guys!”  Hah!  And when we walked back that way, we found them still fighting. 

I walked right up to them in the hopes of getting some super-close-up photos of the fight (and in part in hopes of breaking them up so they could rest for at least a minute), but they ignored me. When I got too close, too, the bigger bully would drag the other one away from me by his face or by pulling on the skin on its neck.  It didn’t look like they were biting hard, no one was bleeding profusely, and no one had ripped anyone else’s snood off, but they looked like their beaks were pinching hard enough to abrade and bruise each other. They must have been exhausted, but neither one wanted to give up. 

We could tell they were all immature males by their feathering (short and incomplete tail feather, and unfinished wing tips), and by the fact that their spurs weren’t developed yet. Some females walked by but were totally unimpressed with the “little boys” and just kept walking. 

As we were coming around the side of the nature center building, we saw the first of FOUR fawns and their moms for the day.  The fawn’s mom was keeping her baby pretty well hidden in the tall grass and stickery shrubs around, but Roxanne and I did manage to get a few photos of it.  I think this first fawn was a female, based on the shape of its face and eyes.  (We can never see enough of the babies’ undercarriages to tell their sex for sure.)  I got one photo of this little girl with her mouth open, showing just her bottom teeth, and then another photo where it looks like she’s grinning, and you can see all of her front teeth.  So cute!

Fawn #1 by the nature center. I think this one is a girl. I love her little “smile”. Columbian Black-Tailed Deer, Mule deer, Odocoileus hemionus columbianus

“Actually, we were kind of on
cuteness overload through the whole walk,
as more fawns crossed our path.”

Fawn #2 was with its mom along the Pond Trail, browsing in the grass with her. I think this one was a little boy. At one point a squirrel jumped out of a nearby tree and startled the little guy. He jumped straight up in the air… looked at us, and then walked over to his mom as though to say, “I meant to do that. I wasn’t really scared.” Hahahaha!

Fawns #3 and #4 were close together.  We’d stopped to look at Fawn #3 who was browsing along the Meadow Trail with its mom, when from behind us Fawn #4 arrived with his mom.  Fawn #4 looked like he was right out of the box, he was sooooooo tiny.  He wasn’t a newborn, I could tell, because the tips of his ears weren’t curled back, but I bet he was no more than a week old.  I got one photo of the two fawns side-by-side and the tiny one is about HALF the size of the other one.

All of the does we came across only had one fawn with them even though it’s “normal” for the Black-Tailed deer to have twins.  All of the does were very calm, even when we approached them on the trail, so I inferred that they were all experienced moms who had had babies before and were accustomed to having humans around them (to a degree).  No flighty or neglectful ladies in this group.

We also saw two bucks in their velvet, a two-pointer, and the three-pointer with the really tall antlers.  “Tall Boy” knows he’s handsome, so he came right down near the trail and walked right past us, showing himself off.  Such a he-man. It looked like the boys were shedding their summer coats and starting to get their winter coats in.  The winter coats are more gray, whereas the summer coats are more tan.

We saw quite a few different galls today including Live Oak Gall Wasp galls (2nd Generation), Pumpkin Galls, Saucer Galls, Two-Horned Galls, Kernel Galls, Urchin Galls, and some Clustered Galls (the first of these that I’ve seen for this season).  Roxanne and I tried to remember the trees the best ones were on so we could show them to the naturalist students this coming Saturday on the field trip. 

We also stopped at the “bee tree” on the Pond Trail to see if the feral colony of honeybees was still there, and they were.  Lots of them were clustered around the opening to the hive.  I don’t know if they were just torpid form the early morning chill, or if they were getting ready to fan the queen to keep her cool when the sun came up a little further in the sky.

 At one spot, we saw a family of Oak Titmice chasing off a Bewick’s Wren that got too close to “their” tree, and at another spot we saw a Northern Mockingbird dive-bombing an adult Red-Shouldered Hawk who was sitting in “its” tree.  Lots of fussy neighbors.  A little earlier, we’d seen what I thought at first glance was a juvenile Red-Shouldered Hawk, but when I got the photos home and looked at them, I discovered it was actually a juvenile Cooper’s Hawk.  (It was pretty far away, and I only got one or two photos before it flew off.)

And, of course, we saw quite a few squirrels including Eastern Fox Squirrels and California Ground Squirrels. The Fox Squirrels were in the trees scraping the husks off of black walnuts: scritch- scritch- scritch- scritch.            

It was so nice outside, and we were having so much fun that we walked for about 4 hours!

Just a Few Before-the-Meeting Photos, 07-24-19

Around 8:15 am I headed over to the Effie Yeaw preserve again for a media / communications committee meeting there. I didn’t know how long it would last, so I took some fruit along with me. It was about 70° when I got there, but it went up to 102° today. Pleh!

Before the meeting, I walked around the nature center building and got to see a Nuttall’s Woodpecker, a Desert Cottontail rabbit, the mama and fawn that we saw yesterday, and a couple of squirrels, including a California Ground Squirrel who was inside a pile of blackberry vines. I was able to get a few photos, but not as many as I would’ve liked.

On the positive side: I didn’t need the food I’d brought along with me and was pleased that the meeting was a relatively quick and productive one.

  1. California Ground Squirrel, Otospermophilus beecheyi
  2. Columbian Black-Tailed Deer, Mule deer, Odocoileus hemionus columbianus

My Article on Oaks Was Published

It was so nice to see my article on Interior Live Oak trees appear online with the Davis Enterprise newspaper today.

You can read it HERE.

It was nice to see the article mentioned in the University of California’s #CalNat program’s Facebook feed (even though my name was spelled wrong. It’s “Hanson”, not “Hansen”. Norwegian.)

Galls and a Fawn, 07-23-19

I headed out to the Effie Yeaw Nature Preserve to do my volunteer work there on the Monarch Larvae Monitoring Project and my trail-walking gig.  It’s supposed to get up to 100° today, so I wanted to get out there as soon as the sun came up to beat the heat.  It was 63° when I got to the preserve around 6:00 am and was already up to 80° by 9:30 am when I left.  I think it would have been hotter except that there was some cloud cover along the river that held off the sunlight for an extra hours or so.

I’m still not seeing any evidence of Monarchs in my plot, but no one else is recording any either, so I’m figuring they’re just not around. My friend and fellow-naturalist Roxanne showed up around 6:30 and we finished up the Monarch work very quickly. We found quite a few different spiders, including a pair of Yellow Sac Spiders and a Western Spotted Orbweaver, along with a couple of katydid nymphs and lots of Oleander Aphids.

We then went for a short walk and came across quite a few different galls including some Erineum Mite Galls on the Black Walnut trees, Two-Horned and Kernel galls on the Live Oak trees, and Saucer and Crystalline galls on the Blue Oaks.  I’m bringing the naturalist class to the preserve next weekend, so we tried to remember which trees had the best galls on them so we could show them to the students.

The big moment of the walk, though, was coming across a doe and her fawn.  Mama was pulling down leaves from the trees for the fawn to eat, and at one point, he looked up, right at us, while he was chewing on a stem.  So cute! His mom was trying really hard to keep him safe and sheltered, so we didn’t get to see him for very long before she took him into deeper brush in the shade.  Still, I was able to get a few photos.

Summer 2019 CalNat Class #7, 07-19-19

We had a great naturalist class today.  Nate got us through half of the chapter on animals, our student Joan Sullivan talked briefly about the trip to Africa (!) from which she’d just returned, and Nate shared some new Black Bear photos from the Silver Spur Ranch.

Adult Black Bear, Ursus americanus, at the Silver Spur Ranch in Lake County.

And we tested the students’ deductive abilities with our “Coyote CSI” activity.  We do this for each class and the students seem to really enjoy it.  We present them with the skeleton of a young coyote and ask them to try to figure out how it died.  Lots of good guesses from this group including: it died of a rattlesnake bite; it died from being poisoned by bad water; it died of a neurological disorder… (It actually died of starvation, but the guesses were excellent.)  We also had samples of deer and elk antlers and showed them the differences between them and how they grow.

A Good Day for Squirrel Photos, 07-18-19

I headed out to the Effie Yeaw Nature Preserve for a walk around 6:00 am.  It was supposed to be cooler outside today, but it was actually warmer at the preserve today than it was on Tuesday.  About 65° when I got there… and it felt humid again.  So, I only walked for about 3 hours before calling it quits.

On my walk I saw a few deer, including the 3-pointer buck with the really tall antlers (which are still in their velvet). I passed by a male photographer who said he’d gotten pictures of a doe and a fawn earlier in the morning, but I didn’t see them.

I could hear the Red-Tailed Hawks talking to each other from different trees throughout the place, and got a glimpse of one of the juveniles, and some good shots of an adult who landed in a tree right next to the trail.

A male Red-Shouldered Hawk, Buteo lineatus

I watched a small flock of male Rio Grande Wild Turkeys jumping up and down under a wild plum tree.  One of them was able to get enough oomph to actually reach the low-hanging fruit and pull it off the tree.  Greedy-greedy. Hah!

And it was a good day for squirrel photos.  I came across several different California Ground Squirrels, including a mama Ground Squirrel who was giving out an alarm call.  She was half-standing on a log with her paws resting on some of the broken branches and twigs coming off of it.  It seemed like such a “human” pose… it made me smile.
