A Killdeer Baby Hunts for Worms, 07-29-18

I went over to the Cosumnes River Preserve hoping to see better examples of wasp galls there and was very disappointed. I found a few, but not nearly as many as I feel there should be this time of year. With 99% of the water gone from the preserve, there wasn’t a lot of anything to see…

There was still a bit of still a bit of shallow muddy water in the slough that ran alongside the road, and around there I was able to find a Killdeer mama and her two chicks. The babies were hunting for bugs and pulling worms up out of the water while mama stood guard. Some of the worms the babies found were longer than the chicks were tall, so the babies would yank them up as far as they could and then gobble the worms up before they had a chance to escape underground again. At one point, both babies rushed over to mom and snuggled under her feathers to warm themselves up a bit before they went scavenging again.

I also saw some tiny jumpy frogs and several crayfish interacting with one another in their slow-moving way. It looked like some of the crayfish had tried building chimneys in the mud, but it was too wet, so the structures collapsed in on themselves.

Even in crappy-looking habitat, Nature seeks to survive.

More Photos from the Sacramento Refuge

Here are some more photos from the Sacramento National Wildlife Refuge.  CLICK HERE to see the album.

I got a video snippet of a muskrat.  It waddled up onto the auto-tour road, grabbed some green vegetation and went back into the tules.  I wonder if it’s setting up a “nest” there.  Where they’re able to, muskrats will burrow into the bank and set up a nesting hole in the ground (with an entrance to the water). If they can’t do that, then they’ll create a structure called a “push-up” made of reeds, vegetation and mud… There are heaps of dead tules in places along the edges of the wetland areas at the refuge, including several of them along the auto-tour route, which I think might make building a push-up really easy for the muskrats…

I saw some Great Horned Owls dozing in a tree, but they were so obscured by branches and twiglets that the camera couldn’t figure out what to focus on, so I couldn’t get any decent photos of them.  And I saw a Killdeer running and squawking along the edges of a slough.  At first I didn’t know what it was excited about, but then I could see it had some babies with it. One of the youngsters was loitering along the water’s edge, and mom was having a fit because it wouldn’t follow her.  Hah!

I also came across a pair of Double-Crested Cormorants (on the little island they often share with the pelicans and ducks), and watched while one of them did a jumping and barking kind of dance around the other before it took off and landed in the water behind the island. I’d never seen that behavior before, so I looked it up.

“…Ritualized agonistic displays are associated with takeoff and landing in both sexes. Before takeoff, individual stretches neck in direction it wishes to go, inflates head and neck and gives t-t-t-t-t call through almost-closed bill. Before landing, often calls urgurgurg and gives Kink-Throat Display, which is given also during working of nest material; lowers hyoid apparatus, making orange pouch conspicuous. Immediately after landing, gives characteristic post-landing display in which it holds head horizontally and slightly below arched and inflated neck. These displays also precede and follow a hop, which functions as symbolic or reduced flight, and occurs in various social contexts…” (https://birdsna.org/Species-Account/bna/species/doccor/behavior) Hah!  How interesting!

The one thing I saw a lot of out there today was insects: lots of butterflies, dragonflies and spiders.  I was happy to see one beautiful Anise Swallowtail, and I also saw some Monarchs, but none of them sat still long enough for me to get photos of them. Among the other insects spotted today were: Variegated Meadowhawks, Garden Orb Weavers, Widow Skimmers, Common Buckeyes, West Coast Ladies, Cabbage Whites and Sulphurs, a Meadow Katydid nymph, Crescent butterflies, Painted Ladies, Pipevine Swallowtails and Yellow-Faced Bumble Bees.  I also found a dead Green Darner dragonfly that was pretty well desiccated by the heat. It’s always sad to find them dead, but the find gave me the opportunity to get some close-ups of the dragonfly’s head and eyes…

It was Hit and Miss at the Refuges on Saturday

I was going to sleep in today, but the dogs got me up a little before 5:00 am, and then I couldn’t get back to sleep. So, I just got up and headed over to the Sacramento National Wildlife Refuge for the day.

When I drove into the refuge I saw a Turkey Vulture sitting on the edge of the sign at the mouth of the auto-tour. It let me walk up pretty close to get photos of it before it flew away. I think those are the coolest birds… I heard some Bitterns “pumper-lunking” but only saw a few in flight, and didn’t get any photos. The bullfrogs were doing their ninja thing, too: I could hear their deep cello-calls, but couldn’t see or photograph any of them…

I did get some good photos of Clark’s Grebes and a few other birds, though.

There was a male Great Tailed Grackle in the tules around the permanent wetlands that was performing for the females. He went through a variety of different calls including its high-pitched “peep”, deep-throated “clap!” and loud echoing “yeeeeeeeeeeeeeep!” I got some video of him, but was interrupted a few times by other drivers along the trail who crept or rushed past my car. One lady parked right next to my car and yelled through the open window, “Did you see the owl?!” Uh, yes… but I’m trying to film a grackle right now… Guh!

I also came across a family group of otters, a mom and dad and two babies. They were one of the permanent ponds but moved so quickly, it was really difficult to get any clear shots of them. I did manage to get a little bit of video, though… until dad saw me, snorted loudly and turned his family around.

When I was done at the Sacramento refuge, I headed over to the Colusa one. I hadn’t been there in quite a while because they took the brunt of the flooding earlier in the year, and were closed to the public for months. It was kind of a waste to go there today, though, because now they’ve drained off a lot of the water (so the surrounding rice fields can have it), and most of it is just a big dirt hole with flowers growing here and there.

One pond was filled with dead carp – stinking bodies everywhere – and others that were slowly dying as the pond evaporates. The carp come up with the flood waters, and when the flood recedes, they get caught in-land and can’t get out. I was surprised that the refuge allows them to suffer slow deaths like that; surely there must be some way to collect them and relocate them.

Where there were spots in the refuge that still had water in them, the water was shallow, and the banks were overrun with water primrose… One interesting thing, though, was that in some of the waterless ponds there were crayfish chimneys, structures the crayfish make by piling up little balls of mud. The bottom of the chimney opens into water (when there is water), and the top opens to the air. They use them to hide in when they’re breeding and getting ready to lay their eggs…

My visit to the Colusa refuge was also kind of ruined because there was a biplane from one of the neighboring rice fields flying around. He’d circle over the refuge, fly down really low, and dump seeds and pesticides on the fields next door. The noise was horrible… You can’t “relax and enjoy nature” when there’s some guy buzz-bombing the place every few minutes. It was ugly… I won’t need to go back there at all for the rest of the year…

A Baby Hawk! And Other Stuff, 05-11-17

DAY 6 OF MY VACATION. I got up around 6:30 this morning and headed out to the Effie Yeaw Nature Preserve for my walk.  It was another gorgeous day, weatherwise – I’m lucking out so far on this vacation with great weather – 55º when I headed out, and up to 70º by the late afternoon.

CLICK HERE for the full album of photos and video snippets.

The first thing I saw when I went into the preserve was a Yellow-Billed Magpie bopping along a lawn area. They’re endemic to the Central Valley (found here and nowhere else on Earth), so it’s always fun to see one… Then I saw a mama mule deer with a yearling, a little boy just starting to get his antlers.  He was very skittish, and ran off behind some brush, but mom was calm and just stood her ground while I walked past her.  She looked pregnant  — it’s that time of year.

I came across several House Wren nests, and watched as one pair of parents double-teamed to get their babies fed. Dad would bring them bugs then fly off, mom would bring them bugs then fly off, dad would sing in a nearby tree and the babies would answer him with creaky little croaking calls, mom would bring them more bugs, dad would fly into the nest to grab the fecal sacs and dump them outside the nest…  I think I stood there for almost 20 minutes just watching the parents fly back and forth…

At another nest, the Wren parents were having a fit because a Fox Squirrel had figured out which tree cavity their nest was in, and was trying to rip into it to get to the eggs.  The entrance to the next was on the underside of a branch that was hanging low near the ground.  I tried to get video of it, but there were weeds in the way, so it’s hard to see anything.  The squirrel wasn’t successful in getting at the eggs – at least nit while I was watching it… You normally think of squirrels as nut- or seed-eaters, but their diet is very varied and often includes birds’ eggs, fruit, and insects…

The one thing I was hoping to see at the preserve was the Red-Shouldered Hawks who have a nest near the nature center there, but when I started out on my walk, I couldn’t see the birds (or the babies I was hoping they had).  Last year, they had two babies.  On my way out of the preserve, though, I looked up and could see the fluffy white head of a baby poking up from the edge of the nest.

I walked around until I could get a better view of the nest, and was awarded with a view of the baby – starting to fledge – as it stood up and walked across the nest.  Then mama flew in to check on him… and I could hear papa screeching from somewhere nearby.  As I continued to watch the nest, I realized there were TWO chicks in the nest not just one… So the parents had twins again!  That was a nice way to end the walk!
