Autumn amblings — seeing insects, birds, a snake and two surprises

It’s been challenging lately to know what to expect as far as weather goes in our area. Following tropical storms Florence and Michael, we’ve had several more episodes of drenching downpours that caused local flooding and closed off some natural areas. The temperatures have gone down to freezing or below in the morning and then have risen to 50-60s F (10-16C); this has sometimes led to steam rising from fence posts and some flowers still blooming which usually would have died by now. This morning, I skipped my walk as the temperature was below freezing with wind, so I re-lived some visits this past month to the Brumley Nature Preserve North. If you, too, are inside sheltering from the weather, perhaps you’ll have the time to amble photographically through this long Brumley walk with me.

Some parts of the reserve are still fairly green, which creates a lovely ambience for leisurely strolling and nature observations. In other cases, we can see the arrival of late autumn and approaching winter. This picturesque tree, one of three near a pond that harbor various bird species, was still very green in late September; now these forest denizens are showing off their gnarly “bare bones”.

     

So some early mornings are quite nippy and others a bit milder, with dried plants glistening with spider webs and dew drops that sparkle in the sun.

 

Some of the insects emerge with the sun to bask in the golden light, like this seed bug (Orsellinae, left), whose coloring camouflages it well against the seed heads, short-horned grasshopper, American bird grasshopper (Schistocerca americana) and different color variations of Asian lady beetles (Harmonia axyridis) who were hanging out on the dog fennel (Eupatorium capillifolium).

 

   

Various birds have been enjoying the winter seeds and especially the winter berries, like the red multiflora rose (Rosa multiflora) and beige poison ivy (Toxicodendron radicans).    

The Eastern bluebirds (Sialia sialis) are quite fond of berries.

They travel back and forth between fruit-laden trees and dried grass seedheads, occasionally stopping on paths to find worms and insects.

The cedar waxwings (Bombycilla cedrorum) also like to gorge on berries, often sharing trees with American robins who enjoy the same meal. Sometimes snagging a berry involves some acrobatic moves.

  

The waxwings are adept at these moves and I only occasionally saw one drop a fruit. They are such elegant birds with their black masks and subtle touches of red on the wings and yellow on the tail feathers.

 

One of my favorite bird species, the ruby-crowned kinglets (Regulus calendula), are also fond of berries. They like suet in gardens but no suet feeders are found in the reserve.
Some of the larger birds, like the Northern mockingbird (Mimus polyglottos), Northern flicker (Colaptes auratus) and yellow-bellied sapsuckers (Sphyrapicus varius), also look for berries and insects as they mostly stay high up in the trees.

 

Purple finches (Haemorhous purpureus) are another species that enjoy late autumn fruit.

  

In early November, I had my first of two delightful surprises at Brumley. It was early morning and as I glanced up at some very tall trees, I spotted movement among the earth-toned leaves. My lens revealed a yellow-billed cuckoo (Coccyzus americanus) – and when I entered it into my bird list for the day, eBird asked me to justify having seen it as it was a rarity this late in the year.

Two other birds that are not surprises but also a joy to see are the hermit thrush (Catharus guttatus) and colorful Eastern towhee (Pipilo erythrophthalmus).

  

It’s always worthwhile to look all around when you walk, not only up at trees if you are a birder or at eye level if you like mammals. I take a lot of bird photos, because I love birds and because they are often easier to see than other wildlife species. But I consider myself more a “wildlifer” than a “birder” since I really am interested in all kinds of animals. That now stands me in good stead during the high-precipitation events we’ve been having. The ponds are filled to capacity and then some, with water flowing over the banks and onto paths.

In some cases, the high humidity has been great for plants; bryophytes are shooting up sporophytes which carry their reproductive spores. As there are over 600 mosses, liverworts and hornworts in North Carolina, I didn’t get the scientific ID for this species.

The rains created new temporary water-filled gullies, where chipping sparrows (Spizella passerina) and white-throated sparrows (Zonotrichia albicollis) have been enjoying baths along with other birds.

 

  

This earthworm (Lumbricina) obviously decided it had to get out of the water-logged earth for a while and I was glad not to have squashed it as I walked along. Its slow progress along the path may not have aided it, though, because there were plenty of robins and other worm-eaters in the vicinity.

 

A large Northern water snake (Nerodia sipedon) was sunning next to a path after the rains as well.

   

So my last visit to Brumley, when I was hoping to capture a golden-crowned kinglet digitally, did not fulfill that hope but ended by giving me a great surprise – my first sighting of a beaver (Castor canadensis) at this reserve. A colleague had seen one there, I’d noted the gnawed tree near the pond, and I had figured out where the lodge was, but I had not yet seen the mammal in the early mornings. Shortly before reaching the pond, I’d stopped to chat with dog owners and mentioned that a beaver was there but I hadn’t seen it yet. Ten minutes later – at 2 p.m. in the afternoon, there s/he was!

It was so surprising to see the aquatic mammal cruising the pond, swimming in large and small circles. As it created small waves and wakes with its head, I pondered why this largely (but not solely!) crepuscular animal was out in the open with people walking by. S/he must have just really wanted to have a good long swim because the animal was out and about for a few hours.

 

Three times, the beaver slapped its tail and dove under with a huge splash when people with dogs strolled by – three times, I missed getting that shot but I did manage to get a photo when the beaver took a time out at the entrance to the lodge.

That was an exciting wildlife spotting – not only did I get to see an animal I rarely see but it was also exhibiting a behavior that I witnessed for the first time. (Previously, I’d seen them harvesting and transporting food to the lodge, chewing bark and felling trees.) As I often go to Brumley in the mornings, being there in the afternoon had another advantage as well – I got to witness a spectacular autumn sunset with the sky almost seeming like a kaleidoscope as the clouds and sun’s rays created rapidly changing skies. I’m looking forward already to my next foray to this reserve!

Tropical storm Florence causing “cabin fever”

The laptop on which I store most of my photos for processing began malfunctioning about a month ago and when it briefly works, I hurriedly back up files on it so I don’t lose them. That has delayed my processing photos and writing more blogs about wildlife I saw this year in Costa Rica and The Netherlands, so I’m taking the opportunity to focus on some current sightings. As Hurricane Florence neared North Carolina, I got in plenty of cat food and litter, bird seed and some non-perishable foods for humans and then cleared the yard of garden art and bird feeders that could become flying projectiles.

In the meantime, the Carolina chickadees (Poecile carolinensis) checked out bird houses as possible shelter from the storm.

How lucky I and most other people in NC’s Triangle area have been so far! The slowly-moving storm turned southeast and is now going northwest, largely bypassing us with the direct impact that had been predicted. We have had rain every day and the ground is very sodden. As I write this now, we are having one of the heaviest downpours of the last week and I keep my fingers crossed that the large oaks and persimmons in my yard do not topple over. Three people were killed by trees falling on their homes and others have had power outages due to fallen trees the past few days. Our neighborhood usually is one of the first to lose power because of the many large old trees we have but so far, so good.

I just had to go out for a walk in the neighborhood today, after only going outside daily to hang and take down bird feeders. Cabin fever had struck, so I spent 90 minutes strolling along. The neighborhood listserv informed me that a few minutes after I passed a certain intersection, a neighbor was almost hit by a falling pine tree, so I was lucky again. And another tree blocked the street further down but we have not lost power yet.

My first destination was the creek downhill from us, which normally rises above its banks, flooding the street next to it. It was nice to see American beautyberries (Callicarpa americana, about which I wrote my last blog) in several neighbors’ yards along the way. The birds have numerous good autumn dining areas available!

When it rains, water from areas north of us runs through our neighborhood to reach Bolin Creek, which also carries stormwater from neighborhoods further upstream.

When I reached the street that runs alongside the creek, I was pleasantly surprised to see that it had not (yet) flooded. (We had at least another 24 hours of rain coming, so it might go outside its banks some time tomorrow.) Some stretches were relatively calm, like this area with a tree that has apparently been marked for removal later (I’m guessing this).with water rising near the walking path.

In a couple spots, the water was rising quite near the walking path (along which some runners passed by as I walked along).

There were pretty wildflowers growing alongside the creek.

 

  

The creek was not only carrying falling rainwater and stormwater from upstream, but also transporting water being funneled into it from our neighborhood as it crossed the street. Not all of the passing drivers were considerate, some going quickly through the water and splashing me as I walked along the sidewalk. In some areas, the water rushing along had to traverse rocks and looked a bit wilder.

I left the creek to walk along neighbors’ yards. One of them had some beautiful spider flowers (Cleome hassleriana), which I have been unable to propagate in my garden, despite a neighbor having given me some to transplant several times.

 

They had some lovely Rose of Sharon (Hibiscus syriacus) as well, which I luckily do have in my yard.

I’m unsure what this particular flower is, but it is lovely.

One neighbor’s large fig tree (Ficus carica) was laden with fruit, which I took as a hopeful sign that my two small fig trees might one day provide this tasty treat as well.

  

As I walked along, I came across two young children who were examining a neighbor’s large tree that had had several huge limbs crack off onto their lawn. The young girl was thrilled with her father’s large umbrella – I asked if she had seen the film Mary Poppins and she said no, but they were going to see the play! Her brother brought me a rock with a leopard slug on it, very proud of his find. He pointed out that it had a hole on the side of its head and I was able to inform him that this was normal for these slugs (something I only found out when I wrote a recent blog about their mating behavior).

After checking in on an elderly neighbor to see if she needed anything, I picked up small fallen branches in my yard and examined the plants, noting that the pokeweeds (Phytolacca decandra) still had a few ripe and some green berries so that the birds and deer would still be able to enjoy a few of those.

My outing in the rain ended with a few minutes watching the tadpoles in a small container, several of whom were well on the way to becoming frogs. It was a pleasant if somewhat soggy walk and so nice to get out of the house again.

In the meantime, my thoughts are with the many people who have been displaced and lost their homes to Hurricane/Tropical storm Florence and – across the world – Typhoon Mangkhut. If you can spare some funds, you can always donate to a North Carolina relief fund and/or the Red Cross/Red Crescent societies.

An update on 17 September: all night our area had torrential rain and some thunder and lightning. Shortly after posting this, Bolin Creek overflowed and led to evacuation of people from a housing complex. It is now almost 8 a.m. and it is still a torrential downpour with repeated tornado warnings. Florence had saved her biggest impact for our area for the end of her journey through North Carolina!

Winter wonderland – sharing and spats at the feeders

I thought I had published this blog in early February and just discovered that I had only saved a draft. Since we had snowflakes last night (in April!), I’m going to go ahead and post this now – a break in the series about Costa Rica! When the snow began falling during our day of one-foot accumulation, the feeders were inundated by some of the dark-colored bird species who tend to come in crowds. At first, they were peacefully sharing space.

 

  

Although I sometimes have a couple dozen red-winged blackbirds (Agelaius phoeniceus) at the feeders, during the storm only one pair showed up for a brief visit and the other birds left them alone.

 

The mourning doves (Zenaida macroura) often share feeder space with other birds, including those that are smaller than they are.

The common grackles (Quiscalus quiscula) are known to other people as domineering birds at the feeder, but those in my yard have always been polite, even though they seem to have a permanent expression that expresses anger.

 

 

The brown-headed cowbirds (Molothrus ater) sometimes share space nicely and sometimes fuss at one another as they vie for a good perch. They don’t try to chase off other species though and are not apt to “yell” at other birds.

The birds who do “yell” are the European starlings (Sturnus vulgaris). Young ones yell at their parents after fledging, begging to be fed. Adults yell at each other when they are trying to all crowd together onto a feeder. And adults yell at other species to drive them away so they can have all the space for themselves.

At my feeders, however, they have found their match in the male red-bellied woodpecker (Melanerpes carolinus). One day, I watched as they managed to intimidate him for a few minutes, but he then returned to the feeder and refused to give up. Now he is no longer frightened of them and stands his ground when a starling does its best to make him move.

    

It turns out that studies have shown that the red-bellied woodpeckers are the birds most apt to resist attempts by other birds to displace them from feeders.

The red-bellied woodpecker also was not intimidated by me at one point. He doesn’t like it when he flies in and notices at the last moment that I am sitting or standing on the porch; often he will swerve away and wait for me to leave. During the snow storm, however, he decided to display his displeasure with my close presence, both from a frontal and dorsal view!

 

  

      

 

I guess that the little bird spats do make for sometimes more interesting birding observations. Seeing the tiny ruby-crowned kinglet (Regulus calendula) warning off a rival a few days before and after the snow melted did show off a gorgeous and brave little bird.

 

 

I’m looking forward to seeing what the springtime observations of animal behavior will reveal.

 

Signs of spring in an uncertain season

As tiny snowflakes fall gently from the sky, my thoughts have left Costa Rica for a bit and turned to the weird weather we’ve been having in North Carolina. I didn’t move to this state for its weather but in the time I’ve been here, I’ve grown to appreciate the climate – we have four seasons but the winters have not seemed overly long and the spring and autumn temperatures are often fabulous.

 

This year, much of February was unseasonably warm in our Piedmont area and people, as well as plants and animals, were enjoying the warm sun and mild temperatures. Crocuses and irises poked their blooms up a bit early and birds were checking out nest boxes.

 

 

 

Butterflies, like this question mark (Polygonia interrogationis) made an appearance (it was getting sustenance from some dog poop left on a bridge!) and Carolina anoles (Anolis carolinensis) emerged to sun in the warmth.

 

 

 

Then on 12 March, we had a day of snow. The male Northern cardinal (Cardinalis cardinalis) and Carolina wren (Thryothorus ludovicianus) sat amid the flakes between trips to the feeders.

 

 

The female ruby-crowned kinglet (Regulus calendula) didn’t seem too perturbed, but the male resident was not happy – his bedraggled red crown was in evidence, both when chasing her away from the feeders and when he was just coping with the wet snow.

 

 

 

When I left for my Costa Rican rambles, it looked like the spring weather might give way to colder temperatures; when I returned 10 days later, it was definitely more winter-like. Then, this past weekend, we had a brief respite. Despite a cold morning start, friend Karla and I visited the Guilford County Farm. The farm personnel had marked off a section of the gravel parking lot where killdeer (Charadrius vociferus) had placed a nest with four eggs. When the babies hatch, they can walk away from the nest as soon as their downy feathers dry.

 

They won’t be able to fly until about 25 days later, but they can feed themselves. The parents will continue tending to and defending them, however. In the meantime, the parents do not come near the nest so as not to draw attention to it and they will try to lead any potential predators away with a broken wing display. They do fly near the nest often, however, and keep an eye on it in between their own feeding sessions.

Karla quickly spotted Wilson’s snipes (Gallinago delicata) flying over the pond and settling at the water’s edge. As we drew closer, we could spot them occasionally, but they blended really well with the vegetation. Below are a couple photos taken at a fair distance with a high ISO and lots of grain – but you can try to see if you can spot the six snipes in the first photo and the two in the second.

Fortunately, one flew in a bit later and I got a couple more recognizable photos!

  

Some Canada geese (Branta canadensis) flew in and headed for the same corner of the pond.

Then, as I was trying to find the snipe in the grass again, I noticed a killdeer looking for insects nearby.

She was accompanied by a male, who at first seemed to be preening but who was actually trying to impress her with some courtship displays.

 

The males will show off their feathers for their (potential) mates, especially raising and displaying their bright tail feathers as a fan.

The female would walk away and he would eventually move closer in an attempt to get a response.

Nearby, we saw three Northern mockingbirds (Mimus polyglottos), two of whom seemed to be males battling over a female. Their dispute was very vigorous and lasted quite a long time. In fact, when they flew away, they were still going after one another!

 

During our continuing walk in the fields and woods near the farm, we saw many other bird species including Eastern meadowlarks, brown creepers, woodpeckers and a pair of kestrels. The woods were kind of strange in that there were very few bird nests visible in the bare trees and also no Eastern gray squirrel nests – in fact, we did not see one squirrel the entire time we were there, which was very odd. An adorable baby donkey (Equus asinus) did greet us as we walked by, though, and our long excursion (about 6 hours) gave us a nice taste of spring. Hopefully, when the snow flurries today end, we will see spring weather come back quickly and be able to enjoy the flora and fauna of this season again. Next blog – back to Costa Rica!

  

Winter wonderland – the bigger and colorful birds

In this second-to-last blog of the snowstorm series, I’d like to feature the bigger and colorful birds who demonstrated how they adapted their feeding habits to the prevailing weather. The Northern cardinals (Cardinalis cardinalis) actually didn’t change their behavior that much – they looked on the ground for fallen seeds and spent plenty of time at the feeders.

They spent some time in the snow-laden trees looking lovely, too.

  

  

The Eastern towhees (Pipilo erythrophthalmus) usually spend their time foraging underneath the feeders in search of fallen seed and they continued that behavior during the snowstorm. Unfortunately, the female was carrying a tick; I had already seen a robin and a junco with ticks on their faces – this may mean that the coming spring and summer will be an especially bad tick seasonal period for us.

 

The beautiful brown thrasher (Toxostoma rufum) looked both on the ground and at the feeders for his meals. Despite his size, s/he never bullied any other bird.

 

 

 

   

The remaining juniper berries on the red cedar trees (Juniperus virginiana) attracted the blue jays (Cyanocitta cristata).

The Northern mockingbird (Mimus polyglottos) was also seeking food there.

 

 

 

 

The cedar waxwings (Bombycilla cedrorum) and American robins (Turdus migratorius) had already been eating the juniper berries in the autumn; the waxwings had been by about a week earlier but now the robins were all over the trees, shaking off accumulated snow to get at the remaining fruit.

 

 

One robin looked as if s/he might have lost some outer feathers but it didn’t seem to affect her balance or flight. Occasionally, a robin also visited the meal worm feeder.

  

On the days following the big snowfall, as the snow melted more and more, the robins began eating it. During a previous snow event, they had joined the cedar waxwings on the roof of my house to get their drinks that way; now they were taking the snow from the trees.

They weren’t the only ones taking advantage of the opportunity. The Northern flicker (Colaptes auratus), who did not visit the feeder, spent a lot of time in an oak tree near the feeders eating snow.

 

  

There were a few birds that visit my yard who didn’t show up during the snow. They included the American crows and the hawks who often make the birds scatter from the feeders: the Cooper’s, sharp-shinned, red-tailed and red-shouldered hawks. They must have been looking for food elsewhere.

Some birds may have also avoided the feeders because of the large number of competitors who showed up, a feature of the next and last blog in this series.
