My nature muse and a delightful experience

Dear unseen spirit,

You are a muse for me who permeates the air and leaves and water and earth that form the sphere in which I feel so at home, at rest yet invigorated, excited, awed, happy and amazed in turn and sometimes simultaneously, in a welter of positive emotion and feeling.

Yesterday, you brought me one of those moments. A smallish, perhaps teenaged, painted turtle (Chrysemys picta), with a smooth ebony carapace with some iron oxide-like highlights, was busy laying her eggs. My friend Lucretia and I stopped to watch.

Lucretia had discovered her while walking a fence line near a lake cove, sticking to that border of mostly bare dirt except for some leaves and twigs so she could avoid the longish grass that could very well be harboring ticks and chiggers – the nemesis bugs for birders and naturalists!

 

Ms Turtle was not quite vertical but leaning like the Tower of Pisa with her bottom in a hole she’d dug and her red-striped front legs anchoring her above. She was using her back legs and toes to move aside dampened clay earth, sometimes moving her body side to side to widen the depression. We wondered how much she’d had to urinate to get the dry ground to a nice malleable consistency; it turns out that painted turtles can store water in their urinary bladder, which helps with buoyancy in the water – and nest digging on land.

When we first stopped, she withdrew her head into her shell and stayed motionless but not for longer than 45 seconds or so. Her natural impulse for self-protection was weaker than her need to procreate, so she resumed moving small mounds of earth.

After some 15 minutes or so, we moved on along the cove, Lucretia noting birds and me looking for dragonflies to photograph. Spring was still in the air with one female widow skimmer (Libellula luctuosa) being chased by 3 to 5 males in an aerial ballet as they sought to be the one who could grab her head and become her temporary mate.

One pair of conjoined dragonflies skimmed the water’s surface while others hovered over water plants or rested on shoreline foliage for a few minutes.

Thoughts of Ms Turtle came back to me and I cut my insect investigations short to go back around the cove to her birthing site. Lucretia was already there and waved me over – she’d just seen Ms Turtle expel two white eggs, which I saw below her tail as she resumed her back-leg maneuvering of damp earth. She was now covering the eggs and perhaps that is also what she had been doing when we arrived. Painted turtles lay from 1 to 11 eggs and we wondered if she had already laid some and was covering them in layers.

At any rate, she was now obviously done with placing her progeny in the nest and was filling in the hole. She deliberately and meticulously grasped balls of soft earth and maneuvered them over the eggs. Her instincts were good and she apparently was doing this all by feel as she couldn’t see what she was doing. Her back legs unerringly found the next clump to move into position and she was quite thorough in making sure it was placed and smoothed over in just the right spot.

The process was slow but careful and as she gathered in the mud, her body began going more and more horizontal – a really noticeable change from when we first saw her more or less standing on end to deposit her clutch.

Ms Turtle was no longer bothered by our presence at all – nothing was going to stop her completing the process, although she occasionally did pause for a moment or two. She’d been at this for at least 70 minutes or so – or perhaps longer if she’d already laid some eggs before our arrival. Lucretia commented on what a hard worker she was!

When Ms Turtle was finally entirely horizontal, resting on the packed earth that was even with its surroundings, she took one more precaution to prevent predators (e.g., snakes, chipmunks, squirrels, foxes, raccoons) from finding her developing offspring. She used her back legs to draw in leaves and twigs to top off the dirt over the nesting site so that it looked exactly like the surroundings!

This, too, was done deliberately and carefully and by feel – never once did she turn around to look at what she’d done. In fact, when she was finished, she set off at an angle to trundle rapidly through the grass to the lake, never casting an eye on the covered nest.

 

We vowed to investigate egg incubation times (on average, 72 days, making 19 August a possible hatching day) and Lucretia tied a paper towel on the fence in front of the site so we could re-locate it. I also tied some weeds into the mesh of the fence.

 

In the meantime, Ms Turtle was making good time to the lake and we saw her tip over the shoreline edge, only to end up on her back. Within 10 seconds, she’d righted herself and plopped into the water, briefly floating and then submerging.

 

 

  

   

We spoke about her wonderful work – even if instinctual, it was amazing to watch and we felt privileged to have borne witness to it. Suddenly, not far off-shore, up popped Ms Turtle; she floated at the water’s surface enjoying a well-earned rest after her double labors (birthing and excavation/reconstruction). Her carapace glistened and she was a beauty to see and admire.

It would be super to be able to see her hatchlings emerge in August. I don’t know if we will be so lucky but recalling their mother’s construction of a nursery will be a great nature memory for sure. And who knows what new event you, my nature muse, will bring along in the meantime – when I arrived home, two of the Eastern bluebird (Sialia sialis) had hatched!

Mother Nature, you always delight and/or edify to be sure!

Many thanks! Maria

                                 

Can you go home again? Apparently so!

This year, I had the good fortune to see both brown-headed nuthatches (Sitta pusilla) and Eastern bluebirds (Sialia sialis) raise broods in some of my nest boxes. I saw the babies fledge, which was truly an enjoyable event.

For some time, the parents continued feeding their babies after they left home, but eventually they got to the point that they could catch or find their own food. As summer progressed, the parents and children both visited my feeders and it was gratifying to see the families thrive. Then during September and October, I saw a behavior that I don’t remember from years past.

brown-headed-nuthatch-i77a7426-maria-de-bruyn-resbrown-headed-nuthatch-i77a7439-maria-de-bruyn-res

The nuthatches started to return to their nest box almost daily. They didn’t check out nearby boxes but went to their original home and today they are still visiting there, sitting on top, fluttering around it and looking inside.

tufted-titmouse-i77a7417-maria-de-bruyn-res

Their frequent visits seem to have intrigued a local tufted titmouse (Baeolophus bicolor) who decided to take a look in their box, too,but that was only a one-time visit as far as I could see.

It’s not only the parents doing this, but also one or more of their offspring. So how true is the saying “you can never go home again” (origin a novel by Thomas Wolfe)? It originally meant that you can’t recapture exactly how things were in your youth because changes take place in situations and places. But people do often journey back to the places where they grew up and apparently birds do, too! Maybe they are wondering if their nest box is still the same good place for a home.

The bluebirds began doing the same with their home nest box as well. They take turns flying from nearby branches to cling to the box and investigate the now empty dwelling. While the nuthatches just lean and peer inside, the bluebirds eventually go inside for a bit.

Oddly, there seems to be some contention involved. For example, when this pair was investigating, they had a little tiff for some reason.

I can only guess that the birds are checking out the nest boxes in anticipation of next year’s nesting season. The nuthatches and bluebirds will begin breeding again around March, although nuthatches might already begin building a new nest as early as December. It will also be interesting to see if they end up roosting in the boxes during the colder winter nights.

brown-headed-nuthatch-i77a4527-maria-de-bruyn-resWatching the nuthatches and bluebirds nest, fledge and feed is an enjoyable pastime and I’m looking forward to seeing them repeat the process next year. In the meantime, perhaps I’ll continue seeing them around the nest boxes this winter – as Pliny the Elder said, “Home is where the heart is” and something is sure attracting them back! (And yes, I know, that is a bit of anthropomorphizing.)

Living above a restaurant

house finch nest 1 IMG_4358© Maria de Bruyn resAt one point in Amsterdam, I lived in a room with a shared kitchen and toilet above a butcher shop. It was a cramped space but I made some nice friends there. Eventually, I painted the hallway with flowers and snails to bring a bit of nature inside. Today, on my way to a prompt writing session, I saw that some birds also choose to live above commercial establishments, including those who established homes above one of my favorite restaurants, El Tigre.

There were three nests (at least – I didn’t look around to the other wall), with house finches (Haemorhous mexicanus) on either side of a European starling (Sturnus vulgaris) home in the middle. Nest 1 had a female bird visiting while a couple stayed inside.

 

The other finch nest was attended by both mother and father.

European starling IMG_4390© Maria de Bruyn resThe nest with starlings had rather large babies in it. At one point, an adult bird flew in with a worm or insect but then took off before feeding anyone – perhaps alarmed when it saw me watching the nest. The babies didn’t say much, in contrast to the somewhat older baby starlings in my yard who make quite a racket asking to be fed.

I wasn’t the only observer, however; a couple house sparrows (Passer domesticus) were also observing the comings and goings to and from the nests.

I had a busy day and didn’t think I’d get to do much nature observation – but then those adaptable birds showed me that even in an urban environment, I can grab a few moments to see what other species are doing on a lovely spring day!

 

Communal nesting – the rookery at Sandy Creek Park

great blue heron DK7A5496© Maria de BruynUnlike Eastern bluebirds (Sialia sialis) and other songbirds, great blue herons (Ardea herodias) like to build their nests near one another, forming what is called a rookery, or colony of nests. The nests are often seen in the tops of tall trees and comprise large twigs and branches that surround grass, leaves and moss. As many as 135 nests have been counted in a rookery, but the one at Sandy Creek Park that I visited this spring had three nests.

The herons return to the nests for several years running. Each year, the males re-furbish the nests in order to attract a mate.

You can see the nests well with binoculars from a walking path, but as I have no binoculars and rely on my camera’s zoom lens, I slogged through forest and marshy terrain on numerous occasions to get close to the pond that had their rookery pine trees on the other side. They were still a bit out of range for my lens, but occasionally I managed to get a half-way decent shot, which encouraged me to return often to follow the nestlings’ progress.I followed them from 8 March through 26 June.

A nest in a tree to the right, which had much more dense foliage, seemed to be occupied by only one or two babies.

There were always 1-4 adults around, including both parents on the nest and “guards”, who took up posts atop nearby trees to watch the nearby skies. This is one reason for the rookeries; the herons want to ensure that there are adults around to protect the nestlings from predators, which include raccoons, crows and hawks, such as this red-shouldered hawk (Buteo lineatus) that was hanging around the nests one day.

The nestlings make quite a lot of noise squawking loudly while they jostle to get first in line for the meal.

Weaker chicks may miss out on getting enough food and can die of starvation, but that didn’t happen at the Sandy Creek rookery. Some chicks were obviously larger and stronger than others, but even the smallest fledglings survived.As they grew, the babies began standing tall and walking around the nest.

great blue heron DK7A9348© Maria de BruynWhen they were close to fledging, they stood near the edge of the nest and practiced spreading and flapping their wings. Sixty days after hatching (much longer than smaller birds!), the young herons were ready to fly and began taking short flights to nearby trees, before venturing out on farther trips. great blue heron DK7A8960©Maria de BruynThe young ones will not breed until they are two years old.

Watching events unfold at the rookery was a new past-time for me this year and likely one I’ll repeat in the future. If you have time and the opportunity, I’d recommend the experience!

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.

gray catbird IMG_3888© Maria de BruynA dense privet tree next to my carport offered a pair of gray catbirds (Dumetella carolinensis) space to construct a well-hidden nest. 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 DK7A8351© Maria de Bruyn res

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!
