A morning at the Butterfly House – with birds, butterflies and more!

Posted on May 29, 2017 by Maria dB

I have all these ideas for blogs in mind, and photos to accompany them as well, but I keep taking new photos and then get behind in posting. One day, the thought came that I could just not go out to photograph and settle down to writing some blogs, but going out for nature walks as often as possible has become a real need in my life. Scientists are saying that “forest bathing” is good for your health and being outdoors and observing and learning about the flora and fauna certainly contributes to my having a happier state of mind, while contributing to my overall stamina (but not weight loss, more’s the pity). I also enjoy “shoreline, field and meadow, creek, river, and backyard bathing.”

It came to me today, after spending 3.5 hours tearing out invasive plants from my yard, that one blog that doesn’t need to be postponed because I keep getting new shots to include is this one – my visit to the Durham Museum of Life and Science Butterfly House with the Carolinas’ Nature Photographers Association.

The Museum had opened the Butterfly House for the morning for our group alone so that we could take photos for several hours without people walking in front of our shots. The Butterfly House is a 35-foot tall, glassed-in dome with many tropical plants such as the Angel’s Trumpet (Brugmansia). One of the four species of birds living in the conservatory, the Oriental white-eye (Zosterops palpebrosus), was enjoying a meal of tropical flowers. The bird would pluck a petal from the stem and then insert its beak into the base; the white-eyes have a special brush-like appendage at the end of the tongue which helps them forage for nectar and pulp.

The white-eyes were brought into the conservatory to help control leaf pests and ants.

The butterflies were gorgeous and the subject of many photos in our group. The postman butterflies have variations within a species.

Common postman (Heliconius melpomene)

Red postman (Heliconius erato)

Another group were the longwing butterflies.

Cydno longwing (Heliconius cydno)

Sara longwing (Heliconius sara)

Tiger longwing (Heliconius hecale) Doris longwing (Heliconius doris)

Numata longwing (Heliconius numata)

As we looked at the butterflies that landed low on flowers, we were able to see the Crested wood partridges (Rollulus roulroul) that are endemic to Asia. They breed in the conservatory, laying their eggs behind dense shrubs, and they help control soil pests in the Butterfly House.

Male Female

At one point, a museum staff-member brought us a group of insects to see up close. One of them, I certainly would not have touched, although it was fascinating to watch: the Asian forest scorpion (Heterometrus).

The Chilean rose tarantula (Grammaostola rosea) was a really beautiful tarantula that blended in well with the tree against which it was placed.

The dragon-headed katydid (Eumegalodon blanchardi) was an interesting creature. I do think its head looks more like a horseshoe crab, though!

The rhinoceros beetle was nice and shiny – I once saw a young boy in Thailand who had one as a pet; he was taking it for a walk in the forest and it looked to be about as big as his hand.

It’s interesting how the patterns on the dorsal and ventral sides of a butterfly can be so very different – you may need to look up both sides to get a good ID of the species. This is especially true of the Blue morpho (Morpho peleides).

The same is true for the male scarlet peacock (Troides amphrysus)

The female shows similarities in her dorsal and ventral wings.

The owl butterfly (Caligo memnon) was an impressively large individual.

The Malayan birdwing (Troides amphrysus) spent much of its time huddled up against the windows but I was able to catch it on a flower.

Two kinds of black-and-white butterflies were fluttering about, the Asian paper kite (Idea leuconoe) and the zebra mosaic (Colobura dirce) from Central and South America.

There is a glass case in the conservatory that has lines of chrysalids hanging on wires. At any time, you may see one or several butterflies that have just emerged and are unfolding and drying their wings. This individual was perched against the glass for the unfurling, giving an excellent view of beautiful feathery antennae.

There were two more birds in the Butterfly House that were beautiful to see. Both from Australia, the zebra finch (Taeniopygia guttata) was difficult to photograph as it spent a lot of time very high up in the dome.

The most beautiful – to me – was the Gouldian finch (Erythrura gouldiae). The colors are a bit like the American painted bunting but they look as if they were put on in blocks of color like a kind of avian Mondriaan painting. I followed this bird around several times in the hopes of getting some nice photos and finally succeeded in my opinion. I’d love to have this bird coming to my feeders!

The beautiful “baker” bird

Posted on May 16, 2017 by Maria dB

Recently, I’ve had the good fortune to observe a small bird at close quarters that I had only seen in a couple glimpses in the past, the ovenbird (Seiurus aurocapilla). Like the ruby-crowned and golden-crowned kinglets, this little avian also has a stripe atop its head. Like the golden-crowned kinglet, the stripe is always visible and orange in color, blending in nicely with its other muted brownish and cream colors.

The ovenbird gets its name from the shape of its nest, which is built on the ground in a shape reminiscent of an outdoor or Hopi oven. It is domed and has a side entrance and can be difficult to see.

The ovenbirds spend the winters in the Caribbean region and Central America and then come North for the summer breeding season. My sightings of the singing male have been at our local nature reserve, Mason Farm Biological Reserve, where I volunteer as an invasive plant eradicator and sometime planter of native flowers.

The male sings a three- to-five note call in the spring as part of his courting behavior and the call varies among individuals. When males are in neighboring territories, they will sing together in duets and it can be difficult to know how many birds are singing.

The sound is so loud that you expect to see a much larger bird and his song inspired poet Robert Frost to dedicate a poem to him.

If he is sitting on a branch, you can eventually find him but it can be a challenge since they prefer to reside in forests with heavy canopy cover so that it is fairly dark.

Once you see him, you may be able to watch for a while as they don’t seem to be very wary of people. This individual let me observe as he groomed on a low tree branch, pausing now and again to let out a few notes.

These birds prefer areas with heavy leaf litter for their homes – the leaves provide cover for their ground nests and they blend in really, really well as they scurry about foraging in the leaves for insects, worms and snails to eat. Both the females and males participate in feeding the fledglings until they can fly at about 30 days.

When they emerge into a patch with a bit of sunlight filtering down through the leaves overhead, you have a bit better chance to see them. Otherwise, you may end up staring at ground cover until you catch a bit of movement and can zero in on the motion to see them.

Photographing the bird is a challenge since they spend their time in areas with so little direct light. My first photos were a bit dark, but then I increased the ISO on my camera considerably (a tip from fellow photographer, Mary – thanks!) and the photos were a bit better. Still, the somewhat darker photos reflect the environment in which you discover these little troubadour warblers. Now that I know where to look for them, I hope to see them more often in years to come.

Late arrivals and late departures

Posted on May 14, 2017 by Maria dB

Since a ruby-crowned kinglet (Regulus calendula) began visiting my suet feeders several years ago, I’ve looked forward to his arrival each autumn so that I can watch him at leisure during the winter months. This past season, however, I began to fear that he had decided to go elsewhere or, more sadly, might have passed away and wouldn’t be coming around again. I did see members of the species at the Haw River in late November and one was feeding on seeds to my surprise.

Then, finally, on the 26^th of December, Rudy turned up at my feeders – weeks later than usual but to my great delight! And where did he go for a bite to eat? In the past, he loved my suet but now he, too, was feeding at one of the seed feeders!

Shortly thereafter, I discovered I now had two ruby crowns in residence as they began vying with one another to claim the suet area as their territory. After thinking that I would have no jeweled visitor this winter, it turned out I had two, leading to a happy dance as I gazed out of my living room window.

The golden-crowned kinglets (Regulus satrapa) have a single feather covering each nostril; this doesn’t appear to be the case for the ruby crowns. Their tongues are often in sight when they open their mouths in anticipation of getting a bite. I wondered if the tongue is sticky to help them snatch food while hovering; an online search did not net me any references about kinglet tongues, however.

Normally, these hyper-active tiny birds seek insects and arthropods as meals, including spiders, pseudoscorpions, aphids, bees, wasps, beetles and ants. But my home-made suet has proved to be a big draw (also for other birds with whom they must compete for space).

The ruby-crowned kinglets will often hover in front of a feeder, sticking out their tongue to snag a bit of suet before they fly to a perch.

As winter progressed, it looked like the yellow-rumped warblers (Setophaga coronata) decided to copy their style, also hovering and snatching on occasion.

I decided to leave the dry stalks of the scarlet mallow and butterfly bush in place this past winter so they had perches close to the feeders. They made a nice “studio” for some portraits!

After a while, since there was a lot of traffic at the feeders, I began smearing suet on the mallow stalks, which proved to be a big hit. The ruby crowns alighted and fed calmly, a big change from their usual frenetic pace. (A few other birds also enjoyed this option, including the Eastern bluebirds and yellow-rumped warblers.)

Sometimes, they went through a bit of head contortion to snag some of the treat.

These kinglets surprised me again in January when they began visiting the peanut feeder, too. I watched as they pecked off tiny bits of peanut; I suspect they also might have been looking for ants or other insects around the nuts.

When it rains, these little avians can look quite bedraggled! But they didn’t appear bothered by the snow flurries.

Normally, these birds are in what seems to be constant motion, scarcely stopping for a second in their quest for food. A large privet bush near my feeders, however, has become a resting and hiding spot for them. (Yes, I know, privets are invasive plants and should be removed but this particular shrub provides a get-away for the feeder birds when the sharp-shinned and Cooper’s hawks fly in for a raid and the catbirds love to build their nests in this particular site.)

I continued seeing ruby crowns during my nature walks, although not as reliably as in my own yard. They were in residence at the Jordan Lake woods and a small wooded area near Chapel Hill’s Senior Center.

One day at the Haw River, I witnessed a territorial dispute between two males who were claiming certain trees as their own.

I stopped seeing the ruby crowns at my feeders around the end of March and assumed that they had embarked on their migration up North for breeding season. On 9 April, I was surprised to see one in the woods bordering Jordan Lake.

On 18 April, one appeared in a cedar tree in my yard.

And then on the 22^nd of April, I spotted one high in the leafy branches of a willow oak in my front yard. I’m guessing that perhaps this bird was stopping for a rest as it traveled from further South on its way up North; I didn’t see it visit the suet feeder.

I miss my little kinglet companions in the spring and summer; hopefully, they won’t wait so long to appear again later this year.

Back to blogging with the golden crowns!

Posted on April 23, 2017 by Maria dB

Litter boxes scrubbed, bird feeders filled, other chores waiting but I’ve decided to end my blogging hiatus on this rainy and somewhat gloomy Sunday morning. This and my next blog will feature two of my favorite birds and then I hope to treat you with a nesting saga as spring is well underway.

With a lovely ruby-crowned kinglet visiting my yard every year for the past four years, I’ve developed a particular fondness for this tiny avian species. This past autumn and winter, my partiality expanded to include their jeweled cousins, the golden-crowned kinglets (Regulus satrapa), who seemed to have favored our geographical area with an irruption (an ecological term for a sudden increase in an animal population). Whereas in previous years, I felt lucky to catch a glimpse of a golden crown during their months-long stay in North Carolina, they appeared to be everywhere this past winter and in full view to boot.

The golden-crowned kinglets are about the same size as the ruby crowns and similar in overall body color except that they also have a black eyebrow stripe.

While the ruby-crowned males only flash their red crests when mating or upset, however, the golden crowns have a permanent yellow stripe atop their heads.

The male golden crowns can sometimes be distinguished by the fact that there will be a hint of red in their golden crest.

Like the ruby crowns, these little insect foragers are in constant movement as they scour branches, shrubs and plants for a meal. Their varied diet includes beetles, flies, crickets, butterflies, spiders, and bees and wasps. In the winter, they will also eat some seeds.

Searching for the insects often means they hang upside down from branches as they look at the underside and in crevices for their next bite to eat.

They also hover mid-air to snatch an insect or fly.

The golden crowns sometimes sit still a bit longer than ruby crowns so that you have a chance to get off a few photographic shots before they resume their dietary searching. And this year, one of those photos placed me among the winners in a small local competition.

These birds are not much bigger than hummingbirds, but like the hummers, they also undertake a long migration twice yearly. Their winters are spent throughout North America but for breeding they travel to the far North and mountainous Northwestern areas of this hemisphere.

This year, many places had mild winters but if they arrive in the North before spring-like temperatures arrive, they are able to survive nights as cold as –40 degrees; sometimes, they huddle together to keep a bit of warmth. Their lifespan is several years, with the oldest recorded golden crown being a banded male who was at least 6 years and 4 months when he was recaptured in Minnesota in 1976.

This species prefers life in coniferous forests but it seems if a few spruce and pines are around, they will settle in. I saw them in a small and somewhat sparsely vegetated area near a senior center, an arboretum, along the Haw River, and in the woods and bogs of various nature reserves.

In the United States, the number of golden-crowned kinglets declined 75% between 1966 and 2014. Habitat loss has contributed to this. However, spruce reforestation in the Eastern USA may have contributed to a more recently seen increase in numbers of kinglets. I’m very glad that they are not (yet) an endangered species and I hope we get to see them a lot next winter, too!

Love my yard!

Posted on January 1, 2017 by Maria dB

2016 began with distress for me, having just been admitted to hospital in considerable pain and worried about expenses. So when I was able to get home again and find diversion from the necessity of self-administering an IV medication twice daily by admiring what nature has to offer in my yard, it was a more-than-welcome event.

Even when my mood is down, walks in nature soothe my spirit since my mind becomes totally absorbed by what I’m observing and there’s no space for any other thoughts. Even aches and pains recede to the background so when I can’t get out to a reserve or park, taking advantage of the little plot of land I call my own is a real delight.

The yard has everything – plants, insects, amphibians, reptiles, birds and mammals, which is very cool indeed. Spring and summer are especially lovely with the blooming flowers and I’ve taken care to include many native vegetative species among the plantings.

The flowers and shrubs not only attract birds but many species of insects, too, and give me plenty of chances to practice photographing bees in flight and butterflies nectaring. The Eastern carpenter bees (Xylocopa virginica), and European honey bees (Apis mellifera) were good models, as were the Eastern tiger swallowtails (Papilio glaucus) and American lady (Vanessa virginiensis) butterflies.

The front yard has one small pond with blue pickerel weed (Pontederia cordata) and the back yard has two ponds and a heated bird bath in winter. Deer, raccoons and birds, like this American robin (Turdus migratorius) use these as watering holes.

Fish live in one pond along with green and/or bullfrogs (Lithobates catesbeianus). Occasionally, I’ve had to rescue an adventurous Eastern box turtle (Terrapene carolina carolina) that didn’t seem able to climb out again on the logs provided as bridges out of the water. Other turtles trundle around in other parts of the yard.

Raquel raccoon (Procyon lotor) and members of her family usually appear at night, as do the local opossums, of whom I have few photos. When Raquel is expecting another brood or in nursing mode, she gets more adventurous and comes round in the daytime.

The white-tailed deer (Odocoileus virginianus) come by all months of the year and provide opportunities to see how the fawns learn about the other creatures sharing their space.

It’s interesting to see how button bucks are followed by yearlings with nubby antlers and eventually grow up to become handsome 5- or more point bucks.

This past year, one of the bucks was kind enough to drop one of his antlers in my yard as a souvenir.

The Eastern gray squirrels (Sciurus carolinensis) provide endless amusement – one way is by investigating various techniques to find a way onto the bird feeders. These are largely unsuccessful, even when they climb up on the roof to see if they can launch themselves far enough to reach a feeder pole. This year, however, one enterprising squirrel managed to finally get onto a feeder by climbing up a rather large sunflower stem that held his/her weight until it bent over close to a pole.

Their antics as they chase one another in play and for amorous purposes, too, are also quite entertaining.

It’s fun to watch them caching seeds as well; sometimes, they decide a spot in the middle of the lawn is the best hiding place!

They often will chase non-family members away from the food I put out on the ground – seeds, bits of bread and apples for the birds (crows and catbirds are especially fond of apples). They are usually (not always!) willing to tolerate the Eastern chipmunks (Tamias striatus) who come to get some goodies, too.

The Eastern cottontail rabbits (Sylvilagus floridanus) don’t often go for the bird food but prefer to munch on the grasses and other plants growing on the “lawn”.

I was surprised this summer when I discovered that the beautiful neighborhood gray fox (Urocyon cinereoargenteus) was fond of bread.

Her presence in the yard reinforced my resolve to no longer let my former indoor-outdoor cat, Jonahay, out by himself anymore. He has almost reached the ripe old age of 18 years and is going strong despite suffering arthritis, mild kidney disease, mild dementia and deafness. But all the years of having roamed outside have preserved a strong will to go outdoors so I take him for walks around the yard, which give him opportunities to mark his territory anew. (My other two cats are strictly indoor felines, although one of them likes to escape now and again.)

Two years running now, my yard has served as a venue for a citizen-science bird banding exercise and it’s always a pleasure to see banded birds returning to the feeders, like Corey catbird (Dumetella carolinensis) who enjoys American beautyberries. They also include my intrepid Carolina chickadee (Poecile carolinensis), Chantal, who unfortunately lost a leg (I think because she had scaly leg when she was banded and the bands were too tight but I don’t know this for sure). She is a feisty little bird and manages to balance remarkably well on her remaining leg; her daily return is always a joyous sight for me.

2016 was an exciting year as far as caterpillars went since a large sphinx moth caterpillar (Paonias) graced the yard for the first time (at least that I had noticed). Cute little jumping spiders (Salticidae) climb onto bird nest boxes and Eastern eyed click beetles (Alaus oculatus) are found in the leaf litter.

Unfortunately, some of the stink bugs (Halyomorpha) make their way into the house so that I have to take them back outside. One of my cats made the mistake of eating one that I hadn’t got in time and she ended up quite sick, even foaming at the mouth!

Occasionally, mice (Mus) get into the house. The cats don’t eat them and aren’t out to kill them but if they catch one at night and I don’t awaken, the rodent will be dead in the morning. Otherwise, I manage to get hold of the animal (sometimes with a lot of effort) and let it go outside again.

The snowberry (Hemaris diffinis) & hummingbird clearwing moths (Hemaris thysbe) are delightful.

And so were various birds that visited my yard for the first time this year (or at least as far as I had noticed)! They included the black and white warbler, chestnut-sided warbler and Northern parula. Here are three more, plus the beautiful great crested flycatcher (Myiarchus crinitus, left), which I’d seen before but not well.

Red-eyed vireo (Vireo olivaceus)

Scarlet tanager (Piranga olivacea)

Yellow-billed cuckoo (Coccyzus americanus)

I’m so pleased to begin this year in my home and really hope that circumstances in 2017 will allow me to continue enjoying nature, especially in my yard as I work to make it ever more welcoming to the local wildlife. And I hope all of you who read my blog will have many opportunities to get out and appreciate our beautiful natural world, too! Happy New Year to you!
