At the Ibis Rookery Again, 06-26-19

It was kind of a whirlwind trip today: left the house at 9:15 am, got to Woodland around 10:15, went to the White-Faced Ibis rookery at 10:30, and left the rookery around 12:30 pm.  Phew!  The weather did cooperate. There’s no shade at the rookery and I was worried it would be too hot there, but it was in the 70’s with a stiff breeze blowing, so temperature-wise it was nice.  The wind kind of played havoc with my birding scope, though, and threatened to knock it over a few times, so I had to put it back into the car.

 I was joined at the rookery by my naturalist graduates Karlyn, Kristie and her husband Joe (and their son-in-law Zak) and three of my current students Alison, Linda and Gina. They had never been there before and were surprised by the number of birds they were seeing right there in the middle of town.

The water in the pond where the ibises were actually seemed HIGHER today than it was the last time I was there and some of the established nests were already underwater.  You’d think the people who control the pond would take that into consideration. I saw several eggs abandoned and floating in the water. So sad.

Along with the large gathering of ibises – talking to each other, gathering nesting material, sitting on their nests, flying back and forth – we also saw a few American Coots (one sitting on a nest and a few with babies), some Killdeer, a female Great-Tailed Grackle, some turtles (but we couldn’t tell if they were the native species or not), Black Saddlebags and Variegated Meadowhawk dragonflies and Familiar Bluet damselflies, including a pair “in wheel” (mating).

Watching the ibises pull nesting material from the bank I was surprised to see that they didn’t go for the dried grass. Instead, they drew up soggy grass from under the water at the edge of the pond and yanked it out by the beakful.

At the rookery, we also talked a little bit about the floating nests made by the ibises, grebes and American Coots. According to The Earthlife Web: “Coots build nests which though surrounded by water have a foundation of vegetation, which reaches the ground below. Interestingly the Horned Coot, Fulica cornuta, which breeds on mountain lakes in the Andes where water weed is scarce, build a foundation of stones nearly to water level before building the actual nest. More adventurous are various grebes. Grebes build the nests in shallow water, and though they are often anchored at one or two points they are basically floating on the water. This is necessary because grebes which are primarily water birds are very clumsy on land and find life works better if they can swim right onto the nest.”

I really suspect that the Coot there had actually commandeered the ibises’ nests rather than building their own. Hah!

The students all seemed to enjoy themselves. One of them, Alison, actually did some quick watercolor paintings of the birds while we were there.  A couple of the students also complimented me on the classes and said I was “a natural teacher”.  It was such a nice outing.

Lots of Springtime Insects, 04-20-19

I got up around 6:30 this morning and headed out to the American River Bend Park. It was overcast and in the 50’s when I went out, but by the time I got back home, around noon, the clouds were breaking up, and it was sunny and breezy for the rest of the day. Just lovely.

I wanted to see if I could find butterfly eggs at the park, and I was able to find some, but only on my way out. So, it was a long wait for the pay off, but I found a pipevine with several groupings of eggs on it. Actually, my photos turned into a kind of unintentional “study of pipevines” with pictures of the leaves, twining vines, seed pods, etc. It’s such a cool-looking plant.  In Victorian Era gardens it was all the rage; now people don’t plant it much anymore – and I think that’s partly because everything but the vines themselves die off each year, so it just looks “ropey” for half of the year.  It’s a boon to the Pipevine Swallowtail butterflies, though, who literally can’t live without it.

While I was there, I saw a European Starling come out of her nesting cavity, so I waited by the tree to see if I could get a photo of her when she came back. Smart bird, though, she flew in behind me, making me turn as she went by, and went back into her cavity with an angry grumble.

I also saw some Wild Turkeys, including a leucistic female, and while I was watching them a bonded pair of Mallards came flying in and landed right near my feet. There was also a bonded pair of Common Mergansers on the bank of the river. These ducks are sometimes referred to as “Sawbills” because their bills have a serrated edge, which helps them hold onto the fish they catch. (They’re fish-eating diving ducks, as opposed to filter-feeding dabbling ducks like the Mallards.)

Saw lots of Craneflies (Mosquito Hawks) all over the place and Elder Moth caterpillars in the elderberry leaves. There were also a lot of Tussock Moth caterpillars, little nests of earwigs, some micromoths, and a mayfly that had just shed and was hanging next to its exuvia. This time of the year is soooooooooooooo interesting! I was surprised to see the earwigs snuggled in the tops of mugwort plants. I thought mugwort was a kind of natural insect repellent. I guess no one told the earwigs.

There were a lot of still-green Oak Apple galls in the trees, but I was really happy to come across some second-generation galls from the Live Oak Gall Wasp.  The first-generation galls are really obvious and visible: round balls covered in spines.  The second-generation galls are tiny and sit on the back of the leaves; they look like upside down volcanoes. Finding them is difficult, so I’m always excited when I get to see them.  The first generation of this wasp is comprised of all females that reproduce asexually, and the second generation is comprised of males and females that reproduce sexually. Cool, huh?

And while I was watching a male House Wren, I saw him look down below him. There was female down there with a feather in her beak. I’m assuming they had a nesting cavity near there somewhere and she was literally feathering her nest. Awwww!

I overdid it again today – because there’s so frigging much to see – and didn’t get back home until around 11:30. Four-and-a-half hours of walking; my body was really mad at me for the rest of the day.

Deer Jousting and Turkeys Mating Today, 03-12-19

I went out to the Effie Yeaw Nature Preserve and got there around 8:00 am. I was joined there by fellow volunteer trail-walker, Mary M. (The-Other-Mary), and we walked for a little over 3 hours. It was a very interesting walk!

Very early into the walk, we came across a Red-Shouldered Hawk who then joined another one… flew into a nearby tree and did their mating thing right in front of us. Around that same area, I could see a European Starling flitting and hopping through the branches of another tree with a large feather in its beak. It was a gift intended for a female Starling, but the male fumbled with the feather, it fell out of his beak and floated to the ground. D’oh! I kind of felt sorry for the little guy. He was trying so hard to make a big impression and failed epically.

The Wild Turkeys gave us a lot of photos ops today, too. We saw two leucistic turkeys, one a male and the other a female. I’d seen a couple of the females around before, but I had never seen the male until today.  Leucistic animals have a depletion of melanin that washes out most of their coloring, but they’re not pure white like albinos.  On the female turkey, her leucism made her look black and white; but on the male it made him look blond, light brown and white. I thought they were both soooo interesting looking. I took a lot of photos of them.

CLICK HERE for the album of photos.

While The-Other-Mary and I were watching one small flock of turkeys, we saw another group running across the lawns straight toward them… and then we saw the coyote running right on their heals! He jumped at a few of them but couldn’t catch any of them. and while this is all going on The-Other-Mary and I are trying to get our cameras to focus on the coyote and follow the action. It was my turn for an epic fail; I didn’t get a single image of the coyote. Dang it!

In another area, we’d stopped to watch some of the male turkeys strutting for a handful of females… and then one of the females approached a male, did a circle dance with him, and eventually let him mount her. The-Other-Mary and I are snapping photos as some other people walked up to see what was going on.  So, I got the chance to do my naturalist thing… I identified the males and females for them, told them about how the males strut, about their snoods, and about what attracts a female to the male. When the female turkey bowed down to the ground, I told them about her posture, how the male will “tread” on her, and how, if she’s aroused, she’ll raise her tail for the male… And while I’m talking, the birds are performing as though on queue.  We actually got to see two matings while we were there. During the second one, an Asian lady came up (who didn’t speak much English) and asked if we could take her photo with the birds in the background.  The-Other-Mary obliged her, but it was right when the male mounted the female, so this poor lady now has a photo of herself with turkeys doing the nasty behind her… It will probably turn into internet gold. Hah!

Further along the trail, we came across a pair of Canada Geese in the tree tops.  I’m not certain, but I think with was the same mama and offspring I’d seen a couple of weeks ago. It looks like the younger one can’t fly very well; only in short bursts.  So, they travel from tree-to-tree, then go down to the river, then go back tree-to-tree into the preserve or onto the lawns.

The other cool thing we got to see was a herd of about 15 or 20 Columbian Black-Tailed Deer, including some bucks that still have their antlers. The big 5-pointer was out there, and he started jousting with another older buck. At one point, when they “locked horns” the younger one pushed hard enough to force the older down to the ground. The older one recovered quickly, but he really had to push back HARD to get himself onto all four feet again.

When we were done with the walk, we went into the nature center to record our hours (we get volunteer hour credit for each hour we’re on the trail), and I got to meet Tova, the gal who oversees The Acorn publication. She thanked me for the article I’d written and sent to her on Red-Shouldered Hawks and appreciated that I was able to include photos I’d taken right there at Effie Yeaw. It’s always nice to put a face to a name…

As The-Other-Mary and I left the building, I had to stop to watch one of their snakes (on display) devouring a mouse. The-Other-Mary didn’t want to see that; and I thought that was funny because she’s ex-military and an avid hunter. Hah! So, we left before the snake finished its meal.

The-Other-Mary was very excited about the walk and said it was “one for the books”. We’re hoping to be able to meet up again soon.
