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.

  6. Variegated Meadowhawk, Sympetrum corruptum,
  7. White-Faced Ibis, Plegadis chihi,

Return to the Ibis Rookery, 07-06-18

There was an overcast which kept the temperatures down a little bit, but also made things very humid. It was kind of yucky.

One good thing about the overcast, though, was that it made early-morning photo taking at the bis Rookery a little easier (because I wasn’t fighting the sun and harsh shadows). I went there again this morning before going to the office…

I am surprised by how quickly some of the Ibis chicks are growing. I saw some that were getting their feathers in, and others that were nearly fully fledged and trying to stretch their wings. At this stage, their flight is more like falling down with their wings out, but they’re working on it. Hah!

I also got to see some American Avocets today, and some Common Gallinules (adults and fledglings). It’s hard for me to tell the baby Gallinules from the baby Coots – unless I can see their legs and feet; then it’s easy. Coots have bluish-green legs and feet with lobed toes, and Gallinules have multicolored legs (yellow, orange and green) with super-long toes.

There was a trio of baby Gallinules sitting together on the shore of the pond, napping, waiting for mom to come and feed them. Every once in a while, one of them would get up, run into the shallow water to drink or bath, and then run back to its siblings. So cute.

I hung around there for about an hour and then headed in to the office.

Ibis Rookery at the Water Plant, 07-03-18

The dog and I headed out right away to go into Woodland and look for the water treatment plant before going into the office. One of my naturalist course graduates, Sonjia, had told me there was an Ibis rookery there, so I had to go see it!

Luckily the main gate was open.  I overshot the pond area and had to turn around, then went down the gravel road, and took photos from my car and the adjacent field. The air quality was horrible this morning, with all of the wildfires burning around the valley, so everything was tinged an extra shade of red-orange.

At first, I only saw flocks of White-Faced Ibis, Black Necked Stilts and a few other shorebirds, but as I watched I could pick out other individual birds like Tricolored Blackbirds and Yellow-Headed Blackbirds, Killdeer, Mallards, Pied-Billed Grebes, Canada Geese and Great-Tailed Grackles.  Some of the grackles were posturing and “dancing” along the side of the road. One of them kept stepping on the tail feathers of the others to mess them up. Hah!  I also found some damselflies who weren’t warm enough to go anywhere yet, so they clung to the stems of the star thistle, sometimes several of them on the same plant. Lots of photo ops… but I felt rushed because I had to get to the office by 7:00 am.

A little further along the gravel road was the rookery area itself, with Ibis practically piled on top of one another in their twiggy nests.  Because it was so early in the morning, most of the adults on the nests weren’t quite awake yet, but in some of the nests, parents were busy feeding hungry hatchlings. If I come back again later in the week, I’ll come a little bit later in the morning when more of the birds are awake.

I was able to see some of the unhatched eggs in nests; they’re a beautiful turquoise blue color. Both parents help to keep the eggs warm. Some evidence seems to indicate that the males sit on the eggs during the day, and females sit on the eggs in the evening, but they can also switch shifts. Both parents also feed the babies (by regurgitation). While I was watching one nest, I saw mom feeding the kids. Then dad flew in, gave mom his breakfast, and flew off again… and mom fed what dad brought to the kids. Lots of barfing and re-barfing going on in that exchange. Eeew! Hah!

The pairs of adults are supposed to be monogamous, but I don’t know if that’s for life or just for the breeding season.  I saw several pairs, some of them interacting very gently with one another. “Allopreening” (mates preening one another) is supposed to reinforce the pair bond.

The baby Ibises have black and white striped beaks and bald heads. They’re so funny looking! And they grab at the parent’s beak to try to get them to open their mouths. Pushy, fussy babies.

In some spots, the female Great-Tailed Grackles were poking around the Ibis’ nests and harassing them. One of them poked its head right in under a mama Ibis who was sitting on the nest, causing her to jump up and turn on it.  It’s not unusual for the grackles to be predatory and try to steal eggs from the nests, but this one was awfully bold!  (I wonder if the Black-Crowned Night Herons come by in the evening to steal babies and eat them… They’re notorious in this area for stealing and killing local Wood Duck ducklings; sometimes killing for no reason and leaving the ducklings bodies lying around.)

I was out there for about an hour and then had to head off to the office, but that was cool way to start my day.
