A morning at Cane Creek Reservoir

The Orange County water authority maintains two recreational areas where it manages water supplies for our area’s drinking and sewage water. One is the Cane Creek Reservoir, where people can boat, fish, bird and relax. When my morning began yesterday with a distressing family situation, for which I would need to wait for news, I decided to visit the reservoir since getting out into nature always helps me handle stress. My foray was rewarding, both in terms of handling the emotional tension and appreciating the marvelous diversity that nature offers for our appreciation.

The marbled orbweaver (Araneus marmoreus) was in the process of building a web, climbing up and down and leaving new silken strands behind as they emerged from the spinneret.

The walking path also held evidence of the passing of a young white-tailed fawn (Odocoileus virginianus). A Carolina satyr butterfly (Hermeuptychia sosybius) was moving from grass blade to grass stem as I proceeded up a hill.

Eastern bluebird DK7A5392© Maria de BruynFirst birds of the day as I left the woods — a pair of Eastern bluebirds (Sialia sialis) that were roosting on a wire. When a pine warbler (Setophaga pinus) wanted to join them, he was given to understand that his proximity was not appreciated.

Next, I caught sight of a Northern mockingbird (Mimus polyglottos polyglottos), very busy grooming near the top of a small tree.

Southern magnolia DK7A5439© Maria de Bruyn resA nearby Southern magnolia (Magnolia grandiflora) was mostly laden with rose-colored fruit but one large bloom was still vibrant and visited by smaller and larger bees.

A number of birds were singing but I didn’t recognize their calls and I saw some birds flit from one tree to another but then I caught sight of one that was dipping into the grass to pick up insects and then sitting still on a branch for a while. It was a lovely Eastern phoebe (Sayornis phoebe), a type of flycatcher with a yellow hue.

This bird flew around a bit, perching in trees, on ropes and barbed wire, providing some nice views of its lovely self.

A blue-gray gnatcatcher (Polioptila caerulea), busy as these small birds always seem to be, was gleaning insects from twigs and branches.

Coming up on the shoreline of the reservoir, I first spotted some least sandpipers (Calidris minutilla) foraging at the water’s edge. This is the smallest species of sandpiper and they are also the smallest shorebirds in North America. They looked very pretty in flight.

The sandpipers landed near some killdeer (Charadrius vociferous), who looked very large next to them.

red-spotted purple DK7A6143© Maria de Bruyn resA red-spotted purple butterfly (Limenitis arthemis astyanax) was mud-puddling on the shore, as was a Sachem skipper butterfly (Atalopedes campestris). A trio of American goldfinches (Spinus tristis) also dropped onto the wet mud for a brief time.

Several flocks of Canada geese (Branta canadensis) came in to the little lake. One group surprised me by suddenly veering in my direction and flying right in front of me, so close that they more than filled the screen of my zoom lens.

Near the end of my visit, a fellow birder kindly pointed out two green herons (Butorides virescens) to me. (Having binoculars is a definite advantage for this pursuit!). One was rather far away but another within walking distance so I snuck up on it in stages.

In the left-hand photo, you can imagine the dinosaur ancestor of this stalker.

At one point, the bird stretched and stared at the sky, moving its head from side to side obviously watching something – it turned out to be a juvenile red-tailed hawk (Buteo jamaicensis).

My sneaking ever closer to the heron was rewarded when I saw the short bird catch and eat a rather large frog for its brunch. It was sad for the frog, but that is the cycle of life.

And when I returned home a short while later, I learned that the family emergency had been handled for the time being. Like the fauna, our own cycles of life are also unpredictable.

New bird generations emerge in my yard!

This spring and summer, I’ve had the pleasure of watching various species of birds in my yard care for new offspring until they have fledged (left the nest). My most recent observations came today as I watched three hatchlings jump bravely into their wide new world. This blog will introduce you to some of my new neighbors; two blogs to follow will go back in time to spring and early summer to describe some nesting I witnessed in local parks and reserves.

I discovered it was there because the parents suddenly began yelling at me loudly whenever I left the carport to walk into the yard and then a bird bander who was visiting managed to locate the nest, which was about 8 feet up so I couldn’t see the eggs in it.

I kept an eye on the shrub and saw the parents were flying in with insects and emerging empty-beaked, so I knew the eggs had hatched. One day, I ventured close and peered through the privet branches and saw a couple little heads sticking up above the nest.

A short time later, the baby birds hopped out of the nest and they stayed in the large shrub for several days as their parents continued bringing them a variety of insects.  As I mentioned in a previous blog, the parents were good providers, sometimes bringing more than one type of insect home in their beaks.

Eastern bluebird IMG_3881© Maria de Bruyn resA pair of Eastern bluebirds (Sialia sialis) laid five eggs in a nest box in my front yard and I was able to record when all the eggs had been laid. Information provided online about time to hatching (12 to 14 days) alerted me as to when I might see newborns.  Only four of the five eggs hatched; the fifth one was broken. I also checked how long it takes for hatchlings to develop until they leave the nest – that can take 16-21 days but usually 17-18 days.

The bluebird parents were diligent about bringing food, mostly caterpillars and insects but supplemented by wild raspberries and dried meal worms that I had made available. It turned out this brood wasn’t too interested in the meal worms; I found a layer of them in the nest when the babies fledged.

Eastern bluebird DK7A3137© Maria de Bruyn RESClose to fledging, the parents began showing protective behavior – chasing squirrels out of the large tree in front of the nest box, flying at other birds that came too close, keeping an eye on me as I sat near the box. Mama and papa removed fecal sacs frequently, flying off with them to a considerable distance from the nest. Only once did I see a parent actually swallow the fecal sac.

 

Eastern bluebird DK7A3081© Maria de Bruyn resMama investigated something odd at the edge of the box one day, flying down to look closely at the gap between the box wall and door. When I looked, I didn’t see anything. She also would occasionally hover in front of the nest box opening, as if she was demonstrating to the babies what they had to do.

I was lucky enough to see all four babies leave the nest. Two of them were definitely stronger than the other two, who couldn’t fly as well and who didn’t seem to have feathers that were so well developed. When I moved close to take photos, the cautious parents dive-bombed me and the young eventually moved across the street. I never saw the young ones at my feeders.

These past few weeks, some bluebirds raised a second brood in my backyard. This nest had some history. First, three eggs were laid, with a pair of bluebirds visiting the nest occasionally. Unfortunately, one day I saw a Cooper’s hawk (Accipiter cooperii) swoop in and it looked like the raptor had caught one of the bluebirds. In any event, the eggs were abandoned. After a few weeks, I had just decided to clean out the nest with eggs when I suddenly saw another pair of bluebirds building a new nest on top of the old one. They, Eastern bluebird DK7A7145© Maria de Bruyn restoo, laid three eggs.

Using the guidance given to me by the Smithsonian Institute’s Backyard Nestwatch Project, I checked the box every three days until the eggs hatched and then every two days to check on the nestlings’ well-being.

I was surprised that the mother was not sitting on the eggs much of the time, but the local Audubon chapter president told me that when the weather is very hot, the parent will not brood because it could become too warm inside the box.

The parents were quite diligent in bringing food to the hungry babies. They occasionally visited my mealworm and suet feeders but mostly just to feed themselves. They appeared to be feeding their babies an exclusive diet of caterpillars and insects and a little bit of suet – no mealworms though.

They were busy removing fecal sacs as well and I discovered that the baby birds actually present the sac to the parent by sticking up their behinds so the parent can pull out the sac. That made for a couple unusual photos!

Eastern bluebird DK7A8316© Maria de Bruyn resI had calculated that today or tomorrow would likely be fledging day so after a doctor’s appointment and grocery shopping, I settled into a canopy chair to observe the box. The parents were very busy bringing food but also taking time to sit in the crepe myrtle tree across from the box to call to their little ones. The nestlings were now sticking their heads out of the box so I figured that fledging was imminent.

As I watched the parents and nestlings for an hour, I also looked around at the other bird activity in the yard. Suddenly, I saw an immature red-bellied woodpecker (Melanerpes carolinus) take interest in the nestlings and it swooped over to the box. I feared for the little ones but one of the parents descended on the larger bird to drive it away from their temporary home.

Eastern bluebird DK7A8532© Maria de BruynAfter a while, I thought bird No. 1 was going to jump but at the last minute s/he crawled back inside. I was occasionally turning my head to observe other birds at feeders and just as I turned my head again, action erupted.

Eastern bluebird DK7A8660© Maria de Bruyn resI was warned because the bluebird parents swooped down from the crepe myrtle tree to fly straight at my head under the canopy of my chair – they were not taking any chances! It turned out that bird No. 1 had flown by me and landed on the side of my screened-in porch, which was where I had been looking.

The parents continued to fly at me, perhaps 6 or 7 times coming very close to my face, so I went on the porch so that they could calm down. Then they began chasing other birds as their young one had flown from the porch to a tree. While they were occupied, I went back to the chair and was able to see babies 2 and 3 jump from the nest box.

It was a partly cloudy, partly sunny morning for the fledging today and then a few hours after the bluebird young flew, the rain began. There has only been a little thunder and no lightning so perhaps this will just be a nice steady rain that we can use and not severe weather. I do feel a little sorry for the new members of our local bluebird society, however, as they have to face getting sodden on their first day outdoors. The parents are visiting the mealworm feeder now; I hope I get to see the babies at my feeders the coming days. In any event, they made my morning very enjoyable indeed and I have a third nesting report to add to Backyard Nestwatch!
