Summer hummers – entertainment for free: part 2

In my yard this summer, the ruby-throated hummingbirds (Archilochus colubris) came late to the feeders (similarly to what other people in the area had reported). Now, there are at least four vying for the four feeders, claiming territory for their own.

 

 

One bird in particular is most likely to be seen enjoying the garden flowers, including blue-black sage (Salvia guaranitica) and hot lips salvia (Salvia microphylla ‘Hot Lips’). In the first two photos below, you can see as his throat starts to bulge more as he sucks up the sweet nectar to complement his mostly insectivorous diet.

 

 

The airborne nectar droplets indicate that sometimes this hummer is a messy eater — or must leave quickly as another hummer is almost literally on its tail.

A couple of the birds spend a lot of time near the nectar feeders, perching close by to chase off anyone who comes near.

 

 

 

They each have favorite perching spots from which they can observe if an “intruder” is coming near the feeder they have claimed.

 

 

Sometimes, they fly up to a higher perch so they can see both the front and back yards – a necessary vantage point if they want to keep an eye on where everyone is.

 

Most ruby-throats have 940 feathers, all of which are replaced each year. As they take little rests, they stretch their feathers and may also groom them.

When a rival approaches, they spread their rectrices (tail feathers) – both when sitting and in the air.

 

Their feathers are beautifully arranged, looking like scalloped decorations.

 

They make frequent trips to the feeders and then occasionally “air out” their tongues.

 

The bill of the ruby-throated hummingbird is one of its most distinctive features. It measures about 0.59-0.79 in (15-20 mm) in length and is said to open no more than about 0.39 in (1 cm wide) at the tip. The hummers in my yard seem to be able to open their mouths to varying extents, however. They consume nectar by extending and contracting their tongues up to 13 times per second.

 

 

 

A quick, only few-second nap is also a frequent behavior. The hummers are almost constantly at the feeders and thus bulking up for their long migration, but they also expend considerable energy chasing one another away from feeders and flowers!

 

 

 

The hummers are not fazed by weather, zipping around rain or shine. Putting on weight and strength for their autumn migration down south is important for survival!

These minute marvels are such a pleasure to watch; I will certainly miss them when they begin their journeys to their wintering grounds.

 

Summer hummers – entertainment for free: part 1

 

When a hummingbird other than a ruby-throated hummingbird (Archilochus colubris) is seen in the Triangle area of North Carolina, it is listed as a rare bird on the Cornell Lab of Ornithology listserv. One year, I did have a chance to see a buff-bellied hummer visiting in a nearby town though; another year a rufous hummer frequented my own feeders in the winter. Mostly, however, it is the ruby-throats who take up residence at my address, which is just fine as these feisty tiny birds provide loads of entertainment.

 

During a trip to Quebec earlier this year, we also saw ruby-throated hummingbirds there – early arrivals during the spring migration.

 

A few years ago, one of my blogs focused on their preening and cleaning, so this time I’ll mostly feature some of my favorite photos of them taken this summer in various places. (When looking through the shots, I had a LOT I liked, so this is now going to be a 2-part blog!)

At Sandy Creek Park in Durham, one female hummer had made a coral honeysuckle (Lonicera sempervirens) one of her preferred dining spots.

 

 

A butterfly garden featuring blue-black sage (Salvia guaranitica) and bee balm (Monarda) also attracted her and some other hummers.

 

One female found the bee balm to be a good place to rest, understandable since these bundles of energy have a high metabolic rate. Their hearts beat up 1260 times per minute and they take about 250 breaths per minute even when they are resting! Taking a few sips while remaining perched has to be a welcome luxury.

 

 

 

 

The hummers’ main wing bone, the humerus, is adapted to hovering flight and they have very large deltoid pectoral muscles relative to their size.

 

 

Male birds produce sperm that flows through the vas deferens (sperm duct) to the cloaca. When they mate with a female, they transfer sperm by touching the tip of their cloaca to that of the female; they do not have a penis. Females only have a functional left ovary; the right one atrophies early in her development, which allows her to avoid the extra weight of a second ovary and makes her lighter for long migratory flights.

One big treat for me this year was finding two ruby-throated hummingbird females tending a nest, the first time I had been able to spot this.

 

Later, I was able to take a quick photo of one female collecting cattail fluff with which to line her nest.

Even when several ruby-throats are frequenting an area, the (temporary) coloring of their feathers can help distinguish them. This young male had a few olive-green dots under his eye and a bit of white on the crown of his head.

 

A somewhat more mature male has a little white patch behind his red gorget.

 

They are all little beauties! Second part of this blog is coming up and then on to Costa Rica!

Hungry hairy herons and their caring parents

A little over a week ago, fellow photographer Mary posted a wonderful photo of young green herons (Butorides virescens) perched in a row awaiting their parents. They still had very fuzzy hairdos, reminding me a bit of a row of Albert Einsteins. About 4 days later, I drove to the pond in a senior citizen residential community to see them and they had already lost most of – but not all – the fuzz atop their heads. That didn’t matter though because it was a real pleasure watching them for a while.

 

Friend Lucretia had accompanied me and we were lucky enough to park right near the end of the pond where the sibling group was parked. Only one was out on a limb when we arrived; the three brothers/sisters were in hiding in the thick shrubs bordering the pond.

The bold juvenile may have been the eldest of the quartet as s/he seemed to have lost the most fuzzy feathers.

 

 

S/he groomed, looked around and then yawned hugely – making me think of how I often want to react to much of the news that is shown in the media these days. This was followed by what looked like a smile and happy reaction, which is how I often feel when out taking one of my nature walks!

 

After a while, a couple of No. 1’s siblings began moving around in the brush, eventually coming out into the open.

In the meantime, No. 1 took the time to defecate; gotta take care of those body functions! (It’s interesting that birds all have white poop. The fecal sacs that songbirds take out of nests are white; this bird’s stream of feces was white. Why? Here’s a tidbit of information you might not know: Birds’ bodies do not produce urine as mammals do. Rather, they excrete nitrogen wastes as uric acid in the form of a white paste.)

Another sibling did some preening.

 

 

 

As we walked around the end of the pond, it turned out that Mama was taking a rest there. (I really can’t tell the male from the female adult but for convenience’s sake just identified her as the mother since she was close by.)

 

After a time, Mama took off and ended up in a perch on the underside of a small dock. It made me wonder if that was a good place to fish because the water might be a bit cooler and perhaps fish were schooling there. A good number of turtles were also swimming about there – perhaps the shady area was just a nice break from the sun-warmed water.

 

 

 

While Mama scanned the deeps, a nice song sparrow (Melospiza melodia) and a beautiful Eastern bluebird (Sialia sialis) entertained us with song.

Brown-headed nuthatches, a brown thrasher, and a downy woodpecker (Picoides pubescens) were among the other birds flitting about the trees and shrubs bordering the pond.

While adult green herons sometimes use tools to fish – using twigs or insects as bait – Papa heron was just standing patiently at the other end of the pond, watching the water intently. He suddenly plunged and ingested a small fish, using what one ornithologist called a “bill lunge”, in which the bird keeps it feet in place but stretches its body forward to spear prey with its long bill. Apparently, green herons can also catch prey by hanging upside down from their perches over water.

 

We wondered if he was eating the fish himself or collecting a gullet-full of food for his offspring. Herons namely feed their young by regurgitating previously-swallowed food.

As we continued our walk around the pond, we came upon a great blue heron (Ardea herodias) who had some good luck in getting a meal.

When we arrived back at the spot where the young herons were hanging out, we saw a beautiful gray catbird (Dumetella carolinensis) snag a meal of its own.

One of the young herons was in the water, apparently practicing fishing behavior. S/he caught something but then let it go.

Then Mama suddenly flew in; the foursome greeted her excitedly and Lucretia saw her regurgitate a meal onto the grass. (Unfortunately, this happened behind a shrub that I could not see around so I missed that behavior.) When I had moved over to see the young ones, they had already gulped down whatever food there was and were engaged in vigorous behavior to convince Mama to repeat what she had just done.

 

This gave a fairly good view of the group. One still had a very pink bill while others were getting more yellowish bills on the way to getting dark beaks.

Mama flew off to a tree and apparently settled in for another food-gathering exercise, while one of her young ones called piteously.

 

After a couple hours, we decided it was time to drive back to our own areas of residence, but it was bittersweet having to leave the group of four behind. But they certainly provided us with an entertaining morning, even if that was not their intention! We hope they will grow up with no threats from predators and be able to repeat the process with broods of their own one day. 😊

My one greed that I do not regret

 

My thoughts & walking wander
Sometimes in conjunction
& sometimes on different paths.

The wheezy red-winged blackbird
Calls out time on this quiet Sunday morning.

An hour’s worth of nature should do me today.
Enough to rejuvenate, calm down, re-fill with some contentment.

A dove’s hooo hooooo
A songbird’s chirrups
The hawk’s plaintive cry.

 

A united triumvirate causes the hawk to flee
As it appears to clutch a prize in its claws;
The flight is too fast to decipher its capture.
Nesting & fledging season continues, so the grackles’ vigilance is warranted.

 

As a vulture descends
Circling downward over my head, I wonder
What does s/he know that I don’t?
Or the grasshopper?
The Nez Perce people said: “Every animal knows more than you do.”

 

 

Lichen-covered and veined stones and rocks jut up from the dirt path.
My feet seek purchase since
An injured leg needs no more distress.

 

 

 

 

A silver-spotted skipper alights on spiky purple thistle
Beautiful white patch on velvety brown.

On another day the summer azures caught my eye.
So small with details of their beauty escaping the naked eye.
The wonders of technology bring them closer.

 

 

 

Someone else has been walking here, too,
Where wetlands waters once flowed.

 

The five-lined skink and Carolina anole
Are not coming out today.

 

The beaver pond is placid
The dragons dip and rise
Turtles break surface and sink
Frogs give a cry of alarm, jumping high-pitched into the depths.

A pair of kingfishers
Fly to and fro,
Practicing their observation skills

As they wait for their permanent colors to come in.

 

Leaves are trembling
Branches and twigs waving
The slightest of breezes beckons
And helps the cattails sway a bit.

 

 

 

 

 

It’s hot
Clothing damp and sticking.
Even the honeybee is not staying around long.

 

 

The brown thrasher, on the other hand,
Is enjoying a dust bath and sunbathing in the glaring light…
Until I surprise her/him from behind. Sorry!!

 

 

A three-way Japanese beetle gathering
Is staying put for a while
Eating up the leaves on which they rest.

 

 

A bright American goldfinch stops by.
I do not think of them as sad
Regardless of the name they were given.
Their brief presence makes me happy.

 

Two hours, 20 minutes…
Passed while admiring an eyed click beetle
And acknowledging deceptions in the natural world.

Two not-so-common looking buckeyes delight.
One a little tattered, showing age.
I can sympathize from experience.

 

 

The life-filled ground, plants, water and air
Enthrall.

An hour should do me?

An hour is enough?
It could suffice in some circumstances.
But the one greed I have, which I do not regret,
Is the desire for much more time among the non-human beings in nature.

The trails beckon.
Who’s waiting around the bend?
