Lots of Snowy Egrets, 05-31-19

I got up about 5:30 this morning, fed the dog his breakfast and then headed out to the Cosumnes River Preserve for a walk.

There was little to no water in the “wetland” areas, so not a lot of birds or dragonflies. I walked along the slough on the side of the road, and then walked through the oak woodland to the nature center, and then back to the car.  Along the slough, I saw Tree Swallows, a pair of Western Kingbirds, and a trio of Brown-Headed Cowbirds doing their bowing thing. They were on the top of a tree, so bowing was difficult, and they kept rolling off their twiggy branches. Eventually, they gave up and flew off.

Further along, I came across a small flock of Snowy Egrets who were feeling for things in the water with their feet.  As I was watching them and taking pictures, a Great Egret flew in and joined them. Seeing the great Egret and the Snowy Egrets side-by-side really exemplifies their size difference. It looked like a mama bird with lots of babies around her.  Some of the Snowy Egrets were flashing their top knots at one another. I got the sense that it was a more an aggressive, territorial thing than a romance thing. None of the birds had their long, trailing feathers in; and none of them were sporting the pink blush in the face the Snowies get when their breeding.

Beyond the regular Oak Apple galls, there weren’t a lot of other ones out yet. I saw some Red Cones just starting to grow – looking like tiny red pimples on the leaves of some of the Valley Oaks.  I did see the curling leaf galls and “flower” galls on the ash trees, but not as much as I’m used to seeing.

As I was walking through the oak woodland, I was surprised to see a large flock of American White Pelicans fly overhead. By the time I got my camera up and focused, though, they were gone. It’s always so neat to see those big birds flying.  They don’t look like they should be able to stay aloft, but they’re so graceful in the sky.

I also got a glimpse of a Green Heron when he flew out from the rushes around the bridge area, and up into a willow tree.  There were so many twiggy branches around him, though, it was hard to get any decent shots of him.

Near the nature center, I saw some House Finches, Anna’s Hummingbirds, and a baby cottontail rabbit. The baby was a surprise; my brain couldn’t get itself around how small it was at first, and I just stared at it. I did come to enough to get a few shots of the bunny before it scrambled away, though.

Even going down to the boat launch area, I was surprised by the lack of insects. I was hoping to see dragonflies, damselflies and spiders there, but… nothing.

I walked for about three hours and then started to head home.  My insides were starting to complain, and I hurried to the restroom near the boardwalk area where my car was parked – only to find that the thing was locked shut. Seriously?! Guh! I hate it when that happens.

Bugs and Birds Mostly, 05-29-19

I got up at 5:30 this morning. I would have slept in a tiny bit more, but Sergeant Margie needed to get outside to pee. Since I was up, I decided to stay up and head over to the Effie Yeaw Nature Preserve for a walk. It was about 55° when I got there, and almost 70° when I left.

I saw a lot of the usual suspects at the preserve. Still very few deer around; the boys are off getting their antlers and the girls are off getting ready to give birth to their fawns.

CLICK HERE to see the album of photos.

I did get to see another pair of Mourning Doves working on their nest. I saw the male first, along the trail picking up twigs and bits of dried grass and flying them over to the female. She was sitting in the back of a half-fallen branch of a tree, tucked in a broken bit of bark. Smart girl!

Later on, along the trail, while I was watching a young Fox Squirrel, a California Ground Squirrel showed up, and then a Scrub Jay landed nearby with a green plum in its beak. Wow, lots of photos just within a few feet of one another. I love moments like that.

I walked for about four hours and then headed home.

Cooper’s Hawk Catches a Woodpecker, 09-21-18

I headed over to the Effie Yeaw Nature Preserve for my walk. It was mostly the usual suspects out: deer, birds, lizards, squirrels… But I got to see a Cooper’s Hawk knock a young Acorn Woodpecker out of a tree, tackle it on the ground on the trail in front of me, and then fly off with it! I was able to find it a few seconds later in a tree overhead and got some photos. Those things move so fast when they’re on the wing, I hardly had time to get my camera up before the hawk grabbed its breakfast and flew off with it again. Amazing.

CLICK HERE for the album of photos.

I also saw a Gray Hairstreak Butterfly. They’re tiny things, but so cute… and this seemed like such an odd time of year for one to be out that I had to try to get a photo of it.

I walked for about 3 ½ hours and then headed back home.

Yellow-Billed Magpies and Other Critters, 06-24-18

I headed out to the Effie Yeaw Nature Preserve. It was 68º when I left the house, and 75º when I got back home a little after 9:00 am.

The first thing I saw when I got to the preserve was a huge flock of Yellow-Billed Magpies foraging for bugs and seeds on the lawns near the payment kiosk. I parked in the little parking lot there and took a lot of photos. The magpies hardly ever sit still, so it’s always neat when I can get some decent shots of them. Most of them seemed to have yellow patches around their eyes. That’s not uncommon, especially if they’re molting.

CLICK HERE to see the full album of photos.

There were more deer out this time than there were the past several times I’d gone to the preserve. Mamas are now showing up with their babies. I saw one doe with a fawn that was maybe four to six months old; out of its spots but still snack-sized.

And in another spot, I saw a mom with a newborn, but she was hiding him really well and I couldn’t get any good photos of him. She was down in a shallow gully between two hills and in the shade. Smart mama.

There were lots of California Ground Squirrels out and about. I saw one, though, who looked like it had a broken left rear leg… and whatever injury there was, was being harassed by flies. I couldn’t tell for sure, but it looked like part of the bone was poking through the skin, and the leg and foot were badly swollen. There were other wounds on its body; spots where the fur had been rubbed off or torn out. I wonder if it had been grabbed by hawk or Coyote and then freed itself – at the cost of its leg. I could tell it was in pain by the way it moved, but it was very stoic – no squeaking or crying. Poor squirrel; I wish I could have caught it and taken it to a vet or something.

I could hear the Red-Shouldered Hawks in the preserve screaming at each other, but only caught glimpses of them in flight. No photos of those guys today.

I came across a very small Velvet Ant, all fuzzy and golden. There are hundreds of species of Velvet Ants, so identifying them can be hard. Although they’re called “ants”, they’re actually a kind of wingless wasp – and they carry a very painful sting. According to one article: “In some areas, velvet ants are known colloquially as ‘cow killers’ because their venom packs a painful punch. In addition, their ‘sting’ – the scientific term for what many of us refer to as a ‘stinger’ – is agile and half as long as the wasp itself. This enables the insect to inject venom into a predator from varied angles and free itself.” So, look but don’t touch.

There were also signs along the trails warning hikers about the high-danger of rattlesnakes this time of year, and also a spot where some Yellow-Jacket Wasps had built a nest in the ground. Nature can be tough in the summer!

As I was leaving the preserve, I saw an Acorn Woodpecker drinking out of the water fountain by the nature center. Hah! Smart bird!

As an aside: I read a blog by Ron Dudley every day. He’s a fantastic nature photographer. His most recent post included information about a long-term Citizen Science project headed by Doug Tallamy, PhD, of the University of Delaware that’s been going on since about 2013. He’s trying to determine what birds eat, most specifically what invertebrates they eat, so he’s asking for people to send him photos of birds with insects and other such critters in their beaks. I’d recently taken quite a few of those — including one today of a Spotted Towhee — so I sent them off to him and also gave him a link to my Flickr account, saying he could use any of the photos there in his study if he wanted to. Citizen collect the data (in this case, the photos and forward it on to the scientist for study… that’s what Citizen Science is all about. (http://www.whatdobirdseat.com/)

Lots of Nesting Birds, 04-15-18

I was up around 6:00 this morning.  It was supposed to rain here today, so I thought I’d better get out early if I wanted to get a nature walk in before the clouds got organized. I went over to the American River Bend Park because it’s close by (no long-distance driving) and I wanted to check on mama Great Horned Owl again.

Mama Great Horned Owl was still in her nest with her three owlets. The owlets are now starting to get their primary wing feathers in and they’re very itchy.  I saw mom helping her oldest owlet preen a bit and give him bite-kisses all over his head and neck. So cute!  I notice that when mom is around her babies, she often holds her plumicorns back against her head.  I wonder if that’s a communication thing…

After I walked around for a while, I went back to check on the nest and mom was gone. She must’ve been out hunting…

CLICK HERE for an album of today’s photos.

In a green area across the trail from the owls’ nest, I watched a House Wren singing from on top of an old snag… and then followed him as he flew over to where the nest was.  I got some photos of the wrens poking their heads out of the nesting cavity, and while I was doing that, I noticed that to my right, there were some Tree Swallows in an adjacent tree where they, too, were setting up house in a tree cavity. They were trying to line the cavity with twigs and stuff, but kept getting interrupted by a pair of Nutthall’s Woodpeckers who, apparently, wanted the same cavity the Tree Swallows had. So, just in that small area, I got to see three different species of birds AND their nests.  In the same area, a few yards away, was a second Tree Swallow nest… and I got some photos of that one, too.

While I was doing that, I was near enough to my car to lean on it and rest a little bit… and saw something flash to the ground to my right. I looked over there and saw that there was some hair fluff – like someone had brushed out their dog and left all of the undercoat hair there. There was a tiny White-Breasted Nuthatch grabbing up mouthfuls of the hair and flying off with it to feather its nest. I tried to see where it flew off to, but lost it in the tangle of branches. It came back several more times for the fluff, so I was able to get photos and a little video snippet of it in action.

A few minutes later, when I moved to step away from my car, I could hear a hummingbird nattering away, and saw it collecting bugs from the side of a tree. I followed after it, and was just barely able to make out its tiny nest in a scraggly tree on the other side of the trail. The nest was covered in lichen and blended right into the lichen-covered bark of the tree, but I still managed to get a few shots.

In one area, there were quite a few Scarab-Hunter wasps flying low to the ground. They have special heat-sensors in their abdomens that allow them to detect the body-heat of grubs under the surface of the dirt. When they find a grub, they land, and stick their ovipositor down through the dirt into the grub and lay their eggs in it. Cool, huh?

There were also quite a few Pipevine Swallowtail butterflies around (mostly males today), and one of them landed on the front of my jacket. I was worried he’d get squished by the shoulder strap of my carry bag, so I set him on my shoulder (on the side opposite the strap) and he stayed there for quite a while, hitching a ride while I walked. He even climbed up onto my head for a bit before taking off to sun himself in the grass. I also found more butterfly eggs today, but no caterpillars yet…

I got a pretty good shot of an orb-weaver spider’s web, and also noted that the Oak Apple gall wasps are starting to lay their eggs on the Valley Oaks. New fat, round, green galls are appearing on the trees…

At another point during my walk, I could hear a California Quail shouting out his “Chi-ca-go!” call, and looked all over for him. I finally caught sight of him off the side of the trail and down on the sandy shore of the river. He was pretty far away, but I still managed to get a photos of him before he scurried off into a tangled bit of shrub.

There were a lot of Fox Squirrels around today, “barking” at me from trees almost everywhere I walked. They’re so funny. They’re teeny, but they bark at something as big as me expecting me to be intimidated by their sound. They’re like the Chihuahuas of the Forest.

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

Deer, Goslings and Acorn Woodpeckers, 05-16-17

DAY 11 OF MY VACATION. I got up around 5:30 this morning and headed over to the Effie Yeaw Nature Preserve… It was cool and overcast all day today, and never got over 65º outside.  All of this beautiful weather we’ve been having is on its way out, though. When I got back to work next week, it’s supposed to be over 100º every day… Pleh!

I was hoping to see the baby hawks again today at the preserve, but it was dark and chilly outside, and they weren’t awake yet.  I got a tiny bit of video of one of them rustling around the nest, but no good shots.  I could hear their mom and dad screeching at one another across the preserve, but didn’t see either of them go to the nest… I did get to see quite a few deer, and lots of geese and their goslings, though.

CLICK HERE for the full album of photos and videos.

The first deer I saw was a female – who looked very pregnant – standing in the overgrown native flowers bed near the nature center building. She was eating all the tender leaves on the plants, and some of the flower heads.  Surprisingly, she let me get quite close to her – maybe within 8 feet– and never startled.  She was so calm, I watched her graze for several minutes before moving on.  All of the other deer I saw were also casually grazing… and I saw one buck in his velvet hobbling though the long grass.  It looked like he was favoring his right front leg, but I couldn’t tell what was wrong because the grass came up almost to his shoulders.  I couldn’t see any swelling in the joints that I could see; and nothing looked broken.  Maybe he has an injury to his hoof…

I found some areas where the thistles were thick… and many of them had Painted Lady Butterfly caterpillars stretched out along them, covered with a thin web of silk (which they spin while they’re feeding)… It’s hard to get photos of them when they’re in their webs because the camera keeps trying to focus on the webbing instead of the caterpillars, and the prickles on the thistles stab me in the hands.  I got a few, though.

I also came across a small flock of female Wild Turkeys, and next to them was a group of males, all showing off, fanning their tails, dropping their wings, and snorting through their snoods.  The gals were not impressed and didn’t even look at the guys. I got some video of one of the gobblers and in it you can his snood contract and expand on his face.  On the video you can hear me “chew!”-ing at him, mimicking the noise the male turkeys made when they snort out blasts of air from under their snood.  It made the male turn and look at me, so I could get some good head-on footage of him…

Just seconds after I left the group of turkeys behind to get some shots of another doe in a nearby field, I heard the turkeys all scrambling and gobbling and shrieking frantically, I looked back to see a coyote chasing one of them down.  I ran – Yeah, me, running. Try not to laugh out loud. – after the coyote but lost it in the over-growth.  I couldn’t tell if it got a turkey or not, but as I turned back to the trail, I saw a second coyote running up from the riverside.  He must’ve heard the breakfast call.  It all happened so fast all I got through the camera was a few-second glimpse of the second coyote as it ran through the overgrowth. Got my heart going, I can tell you.

After that I headed to the river bank to see how far up the water was there.  It was up higher than it normally is, but wasn’t “flooding” like it had been earlier. There were quite a few pairs of Canada Geese close to the water, and each pair had a handful of goslings.  It seemed like each group had babies of different ages, from little golden fuzzies to gray-and-black ones that were just starting to fledge.

Now, a lot of times several groups of dominant parents will work collectively to oversee, feed and protect a large crèche of babies, but these pairs weren’t intermingling, and sometimes showed aggression toward one another.  So I was surprised by how close the parents let me get to their kids; some came to within about a foot of me – and the parents didn’t attack or hiss at me.  I was the only person on the shore, so maybe they didn’t think I was much of a threat… One of the parents, though, got mad at another parent’s fledgling that got too close to its fuzzies, and it bit the fledging in the butt and chased it into the water. For the rest of the time I was there, that one fledgling stayed in the water, whining for its parents to come get it… Poor baby. When his mom finally came back to him, he fussed and fussed at her, as though scolding her for leaving him behind.  Hah!

I also saw a lot of Acorn Woodpeckers who were out and about, squawking and “ratchet-ing!” at each other. One pair was in the process of excavating a new nesting cavity in the side of a dead tree near the nature center that had been denuded of limbs and topped off (so it wouldn’t fall on anyone). It amazed me how perfectly round the cavity’s doorway was; like they had used a drill or a awl or something rather than their face.  Amazing.

I walked for about 4 ½ hours, and then headed home. On the way there, I stopped to get the few groceries I had forgotten to put on the list for delivery this afternoon, and got back to the house around 11:30 am. My ankles were killing me, but I think the exercise is good for me…

I relaxed with the dogs for a few hours, and then Safeway delivered the rest of the groceries to the house.  I unpacked those, and then crashed for the rest of the day.
