Avian generations in the making – part 2B: nesting in nature

My last blog looked at birds’ nests in man-made structures and there are plenty of birds who take the opportunity to use such sites. Most birds, however, make their homes out in nature – in shrubs, trees and on the ground. This is a bit of a long blog but I want to share views of different species at work.

There are different types of nests; a few types that we see in North Carolina include:

  • Cavity nests – holes in trees, made by the parents themselves or adopted as a home when birds like the cavities made by others
  • Simple scrapes – these are shallow depressions scratched out on the ground and they may be lined with materials or left to look like the rest of the surrounding ground
  • Cup-shaped nests – these structures are like small bowls and may be lined with materials like those used in nest box nests. They can be made of varied materials – swallows use mud while American robins and other birds use plant materials.
  • Platform nests – these nests are usually quite large and comprise large twigs and small branches
  • Plate nests are a bit similar to platform nests but much smaller and less organized; they may consist simply of a few twigs arranged in a shallow bundle
  • Pendant nests hang from branches.

When birds look for a cavity site, they may seek out a new spot on a tree trunk or investigate already existing cavities. These Eastern bluebirds (Sialia sialis) at Sandy Creek Park were examining one particular hole with interest, but a downy woodpecker was interested as well so there was some rivalry. The female bluebird chose to just sit on a nearby branch while her mate looked at the hole numerous times trying to make a decision.

    

Red-headed woodpeckers (Melanerpes erythrocephalus) excavate larger cavities in tree trunks to raise their broods. They may visit various trees before deciding on a spot.

      

Pileated woodpeckers (Hylatomus pileatus) may use the same holes year after year. They make holes for resting as well as for nesting and often include a “back door” so they can make a quick escape if a snake shows up.

          

Brown-headed nuthatches (Sitta pusilla), like this one at Jordan Lake, can be very industrious in excavating their nest cavities. You can watch them pecking away at the wood of a tree trunk or branch, scattering wood shavings and removing bigger bits of softened wood in their beaks to achieve a hole of the right depth for their babies. (See a short video of one at work here.)

   

I also saw nuthatches making nests on the edges of a farm and near the NC Botanical Garden. The pair working on a nest at the Garden were doing this with a great horned owl on a branch overhead, as well as a red-tailed hawk and crows who were raising a racket. Their presence didn’t bother the little birds; these nuthatches also appeared to have help from a previous year’s youngster willing to help the parents raise the new siblings.

 

 

    

Carolina chickadees (Poecile carolinensis) also dig out small holes in trees and snags.

      

Killdeer (Charadrius vociferous) use scrape nests which may look exactly like the surrounding area; their eggs then blend in really well with the environment and can be difficult to see.

When I first saw this nest suspended from a tree near a bridge, I had no idea which bird had built it. A birding friend had fortunately seen the parent bird fly to the nest – it belonged to a Northern parula like the one shown below (Setophaga americana).

    

I was lucky to see a female orchard oriole (Icterus spurius) collecting nice soft lining materials for its nest this past spring.

         

A red-winged blackbird (Agelaius phoeniceus) was doing the same with cattails – an obviously appropriate source for bird bedding!

       

Mourning doves (Zenaida macroura) and Northern mockingbirds (Mimus polyglottos) make fairly shallow, twiggy nests (“plate nests”). It makes you wonder if eggs ever roll out of them through cracks in the loose, low walls.

   

Many birds make cup nests and spend a good amount of time collecting the materials to produce them. Here you see American robins (Turdus migratorius) gathering grasses – they tend to fill their mouths as much as possible before flying off to the nest-in-the making.

      

Red-eyed vireos (Vireo olivaceus) will also attempt to get several pieces of bark into their beaks before flying back to the home site. The photos here are dark as the bird was deep in shrubs where little light was penetrating.

        

Blue grosbeaks (Passerina caerulea) weave what looks like a cross between a pendant nest and a cup nest; they also add man-made materials such as rags, cellophane, newspaper and bits of plastic.

    

Great blue herons and ospreys are builders of platform nests.The great blue herons (Ardea herodias) carry large twigs and branches to furnish a nest. At Sandy Creek Park they have been using the same tree-top platforms for several years now.

     

Last year, I saw this osprey pair (Pandion haliaetus) build their first nest from scratch; they weren’t enthusiastic about me being in the vicinity and would perch or fly overhead to give me “the evil eye” – sometimes calling to one another to sound the alert that they had spotted me down below.

 

 

This year, they were busy refurbishing the nest – these birds with longer-term mates may use the same nest year after year. Again, they would stop their work to stare me down.

 

The Acadian flycatcher (Empidonax virescens) makes a cup nest that is well-hidden among the leaves of the tree spot it chooses. A friend saw the pair constructing this nest and it was done by the time I visited. It seemed quite a tight fit for mom to sit in while brooding her eggs.

The bird whom I enjoy seeing most during nest construction is the blue-gray gnatcatcher (Polioptila caerulea). These little birds are very active and often don’t sit still for long as they feed in shrubs and trees. When they are busy making a new home though, they take their time to do a good job. First, they locate good locations for the materials they use – leaves, spider web to hold the leaves together and pieces of lichen to cover the outside walls.

      

They affix the lichen carefully to make a really beautiful, compact and elegant little cup. The female then sits in it and moves her body to ensure it gets the right shape and dimensions for her upcoming brooding.

     

The male and female both work hard on the nests and this year I got to see three pairs at work. In two cases, it was lucky I saw them flying to and fro because their nests blended in really well with the tree.

Unlike the cavity and platform nesters, the cup and pendant nesters usually need to build a new nest each year. At the end of the summer, for example, the blue-gray gnatcatcher nest had already deteriorated considerably with the rain and wind, even though it was a fairly calm and dry season.

 

Once the nest is complete, the avian parents brood and feed their babies before fledging and this will be the third part of this series. For now, I leave you with the male and female ospreys as they watch the birdwatcher….

  

Soothing my spirit, seeking solace for the soul

leaf-i77a2875-maria-de-bruyn-resAlthough more people in the USA voted for the Democratic ticket than the Republican one, the electoral college system will likely lead to the installation of a Republican presidency unless election re-counts affect those designated votes. This distresses me greatly given the persons who have been announced as top administration advisers and cabinet members. My work on social issues and on behalf of vulnerable people will continue and is increasing. But in the meantime, to keep from going into a 100% depressed mode, I have sought solace in nature walks and spiritual strengthening in the flora and fauna I see.

painted-turtle-i77a2277-maria-de-bruyn-resToday, I will share some of words of wisdom from a conscientious spiritual leader with you, along with some photos of nature’s beauties seen during my walks at the Cane Creek Reservoir, Sandy Creek Park and Mason Farm Biological Reserve just before and since the November election. It’s a bit of a long blog but offers some visual sustenance to ponder, like the painted turtle (Chrysemys picta, above) at Mason Farm and the yellow-bellied slider (Trachemys scripta scripta) at Sandy Creek sunning in the morning sun despite chilly temperatures. (From a distance, the slider looked a bit as if there was something with open jaws in the pond!)

Taking care of our planet is like taking care of our houses. Since we human beings come from Nature, there is no point in our going against Nature, which is why I say the environment is not a matter of religion or ethics or morality. These are luxuries, since we can survive without them. But we will not survive if we continue to go against Nature.  – Dalai Lama

red-bellied-woodpecker-i77a2988maria-de-bruyn-res

 

Many birds, like this red-bellied woodpecker (Melanerpes carolinus), are busy finding seeds and nuts for their meals.

If we unbalance Nature, humankind will suffer. Furthermore, as people alive today, we must consider future generations: a clean environment is a human right like any other. It is therefore part of our responsibility towards others to ensure that the world we pass on is as healthy, if not healthier, than when we found it. – Dalai Lama

At Sandy Creek, a group of American crows (Corvus brachyrhynchos) flew down to investigate what had dropped to the ground from an overflowing garbage can but they soon flew off to seek more normal food elsewhere.

A great blue heron (Ardea herodias) was stalking the pond for fish; after I saw him (or her) snag a medium-sized fish, he turned his back so I saw the fishing technique from the rear.

The flowering dogwoods (Cornus florida) at Cane Creek still had a few blossoms; at Sandy Creek and Mason Farm, they offered bright berries. On one tree, they made me think of a movie-inspired alien peeking out of the branches with eyes on stalks.

Destruction of nature and nature resources results from ignorance, greed and lack of respect for the earth’s living things. – Dalai Lama

Up until the first morning frost this autumn, butterflies were still around, like this sleepy orange (Eurema nicippe); now that we have had several mornings of below-freezing temperatures, the butterflies are mostly gone as are the majority of bees. A scorpion fly (Panorpa) was in evidence at Cane Creek to my surprise.

In between bird spottings, Eastern gray squirrels (Sciurus carolinensis) chittered at me at all three parks. And I was pleased to see some ruby-crowned kinglets since the one that has enjoyed the suet at my house the past three years hasn’t appeared yet.

…until now, Mother Earth has been able to tolerate our sloppy house habits. However, the stage has now been reached where she can no longer accept our behaviour in silence. The problems caused by environmental disasters can be seen as her response to our irresponsible behaviour. She is warning us that there are limits even to her tolerance. –  Dalai Lama

Some of the birds common in my yard are welcome sights at the nature reserves, too.

Birds and blooms at Sandy Creek Park – more of the “good ones”

moon I77A9993© Maria de Bruyn res

Birds are a favorite photographic subject of mine, even though catching them in late spring and summer is challenging when the lush foliage offers them many places to hide. Their songs and calls and warbles tell me that they are there, but often I need to wait quite a while until I finally catch a flutter of movement out of the corner of my eye to locate them.

 

white-eyed vireo I77A0007©Maria de Bruyn

One early morning, when the moon was still in the sky, I was fortunate enough to see a lot of fluttering in trees near the park’s parking lot – and I discovered an immature white-eyed vireo (Vireo griseus) with a parent who looked as if she or he was really practicing forbearance.

Nearby, a Carolina wren (Thryothorus ludovicianus) was singing loudly; these little avians have an outsized voice so that you can hardly miss them even when they are hidden behind leaves.

A handsome male goldfinch (Spinus tristis) was in a field, while a female was visiting the coneflowers (Echinacea), of which there were various species in the cultivated butterfly garden.

The common grackle (Quiscalus quiscula) scored a meal, while the pine warbler (Setophaga pinus) and blue-gray gnatcatcher (Polioptila caerulea) were busy in the trees searching for caterpillars and insects.

Other birds (and mammals, I think) had been getting crayfish from the ponds but I guess there were so many that they only ate the tastiest parts.

Over at a nearby pond, the Northern rough-winged swallows (Stelgidopteryx serripennis) were swooping over the water and then sharing space on a snag; meanwhile, a mother wood duck (Aix sponsa) led her brood along the shoreline.

In a tree beside another pond, the immature great blue herons (Ardea herodias) were still at their nest at the start of June; later in the month, they were no longer hanging out there.

milkweed I77A0079©Maria de Bruyn res

 

Botanists can have a great time at Sandy Creek, too. The milkweed plants in the butterfly garden attract both butterflies and bees.

Carolina horsenettles (Solanum carolinense) are common but pretty little plants, while the orange jewelweed (Impatiens capensis) enjoys a good reputation as having stem juice that relieves the pain caused by poison ivy for many people.

The fairywand (Chamaelirium luteum) grows profusely on the edges of Sandy Creek ponds and the swamp rose (Rosa palustris) sprouts near them as well.

What makes my walks so interesting is discovering new species. A native grass (Bromus) was lovely; helpful facebook group members gave me suggestions for possible species but we couldn’t narrow it down. The group also helped me identify a plant that I hadn’t seen before, a Germander (Teucrium canadense).

I managed to find an ID myself for a common flower that seems to grow all over the place – the Asiatic dayflower (Commelina communis). It is considered an invasive plant and is on the watch list for North Carolina, but I have to say that I find it quite attractive. Each flower blooms for only one day and to me they look like little faces and make me smile. And so I continue learning as each new walk invariably ends up teaching me something new. Enjoy your day!

See anything good?

Sandy Creek path IMG_4981© Maria de Bruyn resThat’s a common question I get when I am out on one of my nature walks. Since I carry a camera with a large zoom lens and often a smaller camera, too, it’s obvious to passersby that I’m out observing nature. And I realize that when they ask the question, what they really want to know is whether I saw anything unusual or spectacular.

A recent walk at Sandy Creek Park in Durham, NC, was a case in point. I told one couple who posed the question that my most memorable sighting so far had been a male ebony jewelwing damselfly (Calopteryx maculata) – the iridescence of its body and wings in the sunlight was wonderful. They smiled a bit uncertainly and the lady of the pair admitted that she didn’t know anything about damselflies as they walked on.

ebony jewelwing I77A0417© Maria de Bruyn res   ebony jewelwing I77A0469© Maria de Bruyn res

Fragile Forktail damselfly I77A0648© Maria de Bruyn resAn hour or so later, another couple asked if I had “seen any good ones?” I repeated my delight in seeing the male damselfly, adding that the female is not as striking with her brown color and white spots. “Yes,” said the man, “that is often the case with other species. In our species, though, it’s the females who shine.” That may be the case some of the time, but my day was made by seeing a female damselfly that was a member of a new species for me – the fragile forktail (Ischnura posita).

 

My experience is that I find some beauty in almost all the wildlife I see (ticks and chiggers are an exception). So I want to share a few of those “good things” I saw at Sandy Creek Park last month in a two-part blog “tour”. In this first part, I’ll continue on with the insects.

Identifying dragonflies is not easy since the females and males can look quite different. The great blue skimmer (Libellula vibrans) provides an example – the male lives up to his name with a blue hue and large size, but the female shows off her beauty with a brown and yellow abdomen.

The Eastern pondhawk (Erythemis simplicicollis) has distinctively different appearances as a male and female. The adult male is a blue individual, sometimes with a bit of greenish tint; the female – and the immature males! – is brilliant with different shades of green. I remember being excited when I first spotted a female as their green color is so striking.

Eastern pondhawk I77A0721© Maria de Bruyn res  Eastern pondhawk I77A0749© Maria de Bruyn res

blue dasher I77A0172©Maria de Bruyn resThe blue dasher dragonfly (Pachydiplax longipennis) has some stripes, as do some of the bumble bees. The brown-belted bumble bee (Bombus griseocollis) lives up to its name with a brown stripe, while this American bumble bee (Bombus pensylvanicus) feeding on a trumpet vine (Campsis radicans) has white bands. Like honey bees, the latter bee has pollen baskets (corbicula) on its hind legs in which it stores pollen. I enjoyed watching this individual – s/he would dip down into the flower, back up a bit, and then plunge forward again, almost always keeping the pollen basket above the tip of the flower.

The pollen gatherers were numerous during both visits and willing to share the sources of their bounty – here you see a bumble bee (Bombus), syrphid fly (Toxomerus marginatus) and sweat bee (Halictus) feeding peacefully together on a coneflower (Echinacea).

The milkweed plants were attracting many species of pollinators; here an Eastern carpenter bee (Xylocopa virginica) was enjoying a meal.

While there were many, many bees the days of my visits, there were fewer butterflies but the common buckeye (Junonia coenia) was stunning!

 

 

The little wood satyr (Megisto cymela) and dun skipper (Euphyes vestris, to the lower right on the milkweed) were not as colorful, and some people might even call them dull, but they are still nice to see and the Eusarca moth (Eusarca confusaria) was also an evenly colored beauty. I had grown up thinking moths usually fly at night, attracted by lights so it still draws my attention when I see them in the daytime.

Even a somewhat tattered American lady (Vanessa virginiensis) offered a pretty view.

The broad-headed sharpshooter (Oncometopia orbona), a leaf hopper, and the spotted pink lady beetle (Coleomegilla maculata) are tiny but such colorful insects that close perusal of the vegetation helps you spot them (and presumably makes it easier for birds to see them, too?).

Emerald ash borer trap I77A0719© Maria de Bruyn res

 

One beetle that we don’t really want to see is the emerald ash borer (Agrilus planipennis), an invasive species that came to the USA from Asia. The larvae of these beetles kill ash trees and the park administrators have hung a trap box for them to determine whether this species has reached the park.

 

 

Spotting mammals is not always easy at the park but one day fellow birder Jim was kind enough to alert me to an opossum (Didelphis virginiana) in a tree when we met on a walking path. He told me approximately where it was and I spotted that one and another in a nearby tree; I thought it might be a mother and grown offspring but that was a guess and I certainly couldn’t confirm it. As these are nocturnal animals, it was pretty cool for me to see two in broad daylight. The only marsupial found in the United States and Canada is a beneficial animal for us humans (and other wildlife) as they could eat up to 4000 ticks in a week! 

opossum IMG_0605© Maria de Bruyn res     opossum I77A5788© Maria de Bruyn res

One of the pair demonstrated that they can open their jaws widely – watching him/her slowly stretch that mouth offered me a surprise; I would think it couldn’t go any further and the animal continued to show that s/he could really please a dentist who would like lots of space to investigate those teeth.

The Eastern cottontail rabbit (Sylvilagus floridanus) was not so lucky, carrying a fat tick in its ear. Too bad the opossums couldn’t come by and groom him/her and remove that pesky arachnid!

 

The park is not only attractive for the entomologists. Reptile enthusiasts can spot turtles fairly easily, especially in the spring when they are looking for places to lay their eggs. A large painted turtle was crossing a field looking for a spot, while an Eastern mud turtle (Kinosternon subrubrum) was trundling down a paved path one morning, not far from a pond which often has many painted turtles and red-eared sliders (Trachemys scripta elegans), like this one – who must have been a bit bothered by a bird feather caught in its shell.

Which bird could it have been? I’m thinking a swallow – see part 2 of the tour for a view of the species and more of the wonderful biodiversity that can be seen in the park.

 

Hummers haranguing – feistiness in small packages!

ruby-throated hummingbird DK7A0498© Maria de Bruyn (2) resAt times, we may see on Facebook or the Internet a photo or video of hummingbird nectar feeders surrounded by at least 6 and sometimes dozens of these small birds, sharing space as they take turns at imbibing some of the sweet water. Here in my part of North Carolina, however, it seems that the ruby-throated hummingbirds (Archilochus colubris) are just NOT interested in having their territory host family members or neighbors. This species is known for being territorial and those in my vicinity live up to that reputation for sure.

Both at home and in nature reserves, I’ve watched these tiny birds stake out a claim to a feeder or some choice blooms. They drink a little and then will take up a post on a vantage point where they can keep an eye out for other birds. Occasionally, the waiting spot is out in the open and often it is in a nearby shrub or tree.

When they spot a rival approaching the food source, they may either immediately give chase or first engage in a threat display.

Their displays include both posturing and sound. To warn off other birds, they may chirp both quickly and loudly. Their threat postures aim to frighten away intruders by displaying size and strength and include pointing their long bills at the other bird(s), puffing up their throats, spreading and raising their wings, and flaring their tail feathers, .

ruby-throated hummingbird DK7A2247© Maria de Bruyn resThey don’t really use their bills to battle as they need to protect this body part but they can fly into each other. On one occasion, in my front yard, I heard a loud thump when the two birds actually collided during a high-speed chase.

The drive to protect territory is not for lack of food. My yard has three nectar feeders out back and one in the front and three of them have at least four feeding holes. This year, a brightly colored male laid claim to the yard while the female was caring for her brood. When the female and young birds began coming to the feeders, “Red” was not pleased. Later, the young males also vied with one another.

Chittering loudly, they sweep in to make the other birds take off; occasionally they do get a chance to have a short drink before another hummer shows up. At my house, the birds can feed because they have to patrol both the front and back yards and can’t be in two places at once.

I witnessed a similar scenario at the Mason Farm Biological Reserve. There was a spot with plenty of blooming trumpet vines (Campsis radicans) and morning glories (Ipomoea pandurata), which were attracting a variety of pollinators. Three hummingbirds were also visiting and, again, chasing one another from the site as soon as they caught sight of their rivals.

In an area near the Haw River where many wildflowers bloom, a similar scenario took place.

This is the time of year when the ruby-throated hummingbirds undertake their migration to Central America, a distance of at least 1000 miles. They need to store energy for this and may double their body mass while feeding during the preparatory phase. However, it seems to me that chasing away other birds from their preferred feeding sites must take an enormous amount of energy and it seems to be an endless activity. In my yard, it goes on all day long!

ruby-throated hummingbird DK7A1828© Maria de Bruyn resThese birds’ flight muscles take up 25% of their weight; when they rest, their hearts beat at a rate of 250 beats per minute but during flight, their hearts speed up to 1220, so the zipping back and forth and up and down in hot pursuits must use lots of calories and energy. They also may hover mid-air for a while rather than sitting on an outpost twig; the other day, one of Red’s rivals spent a quarter minute suspended about 18 inches from my face, looking me over until Red dive-bombed him.

Once in a while, though, one would have the space to him- or herself for a while and I could watch them feed, afterwards flicking out their long tongues.

When they return next year, I hope to learn more about these wonderful little birds through daily observation in my garden habitat.
