Some beauty to offset a distressing week

This past week in the USA has been rather distressing as far as health and politics are concerned. The COVID epidemic is wreaking havoc and then humans wrought havoc during a procedure intended to be part of a peaceful transition of governmental power. So we can all use a bit of distraction to remind us there is also still beauty in the world and I’ll end my last trio of posts with one more view of hummingbirds – this time featuring the one species that visits my home every year, the ruby-throated hummingbird (Archilochus colubris).

Fortunately, my yard now has several types of plants that offer the hummers natural nectars to complement their primarily insectivorous diet.

The rose of Sharon (Hibiscus syriacus) flowers are a popular feeding site.

They are also fond of the blue-black sage (Salvia guaranitica). My original plants were a gift from birding friend, Gail; now they are growing in four areas of the yard. Sometimes a hummer doesn’t want to hover but uses a nearby prop to offer some less strenuous feeding. And then the bird can close its eyes to thoroughly enjoy the sweet sap.

Hot lips sage shrubs (Salvia microphylla ‘Hot Lips‘), which I got at a garden center, have proved to be popular feeding sites. This is quite a hardy plant.

The hummers also like going to the lantanas (Lantana) and the yellow passionflower (Passiflora lutea), which kindly came to my yard on its own.

 

Another popular plant is the butterfly bush (Buddleia davidii).  Many recommend against planting this bloomer because it can be invasive. However, some garden centers have developed varieties that scarcely seed and that must be what I luckily got as it has never appeared anywhere else in the yard in more than a decade.

It also attracts butterflies, bees, syrphid flies and hummingbird moths, so I’m quite happy with my butterfly bush.

The ruby-throats also do like their nectar, however. After visiting various flowers, they often take a seat near or on the nectar feeder so they can sip at their leisure.

 

They will also do their best to keep other hummers away from the nectar feeder — even when I have as many as three or four feeders available.

They keep an eye out for intruders.

When a rival appears, it can lead to confrontations. Mostly these involve aggressive displays and chasing one another; only very rarely have I seen them actually physically engage.

This past summer, a few laid-back moments occurred when they tolerated one another.

It’s not only the males who are aggressive; female hummers can also be quite protective of feeding grounds. This past year, it seemed that I had mostly males visiting. While a female hummer can have one or two red spots under her chin, usually that is the beginning of a young male developing his ruby-throat.

It can be fun to watch as more spots appear with passing days.

 

Eventually, the males get their fully developed gorget, which can be quite stunning.

The red hue is very dependent on how the light hits their feathers. In some cases, the red feathers almost look black.

  

The hummers take care to groom their feathers.

They take advantage of the rain to have a shower.

There are times when they look a bit scruffy, however. That is when they molt. This process of replacing old feathers with new ones usually takes place on their wintering grounds. This past summer, the hummers seemed to have lingered longer than usual and began molting before their trips further south.

White feathers appear more and more as molting proceeds. And feathers come loose before falling away.

They can look a bit scruffy during this time.

Eventually, they get back to their pretty selves. It always stays fun to watch them flying — at least for me. That is when you can see their tiny feet better.

And you get an idea of how rapidly their small wings move as they hover and soar.

They can beat their wings up to 70 times per second!

It doesn’t seem to me that I’ll ever tire of watching these tiny fliers; they always are entertaining. I hope seeing some photos of them in action have provided you with a brief respite from the worries of the world, too.

Kinglet capers – finding food and enjoying short rests

It seems that at least once a year, ruby-crowned kinglets (Regulus calendula) feature in my blogs; they are one of my favorite bird species and I always enjoy seeing them again and again.

These small birds are bundles of feathered energy, almost constantly in motion as they seek insects, which form the bulk of their diet.

 

They are only slightly larger than ruby-throated hummingbirds: 9-11 cm (3.5-4.3 in) long versus a length of 7-9 cm (2.8-3.5 in) for the hummer.

When they scour the vegetation for food, they may be flicking their wings continuously.

Fortunately, they do take little breaks now and again, so we can admire their beauty.

These breaks often last less than minute, however, and often are even briefer so you have to be ready and waiting to capture a photo.

I’ve been lucky this fall to find a few spots where I know some kinglets are hanging out, so I get to see them quite regularly.

My yard-visiting kinglet has returned for the winter season as well; I usually see him mostly at the suet feeder, where he will hover like a hummer as he takes quick bites of peanut-flavored vegetable lard laced with grits, oatmeal and nuts. He is a bit more gray in color than many other kinglets.

I’m wondering if this year’s bird is the same one who has been here the last 5 years. Unlike my previous visitor, I’ve seen him take a seed from a feeder as well. This has not happened before, even though it is known that they eat berries and seeds in winter.

This year’s bird also seems a bit shyer than my kinglet(s) from previous years. When I lift up my camera, he tends to take off. My resident the last years was not shy at all, a couple times actually perching on the suet feeder as I carried it to the pole. Still, my yard visitor’s anxiety has been nowhere nearly as obvious as that of another kinglet whose story I will relate in the next blog!

 

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!

Costa Rican rambles 5B: the Talari Mountain Lodge and environs

 

After fully experiencing the “honey dew” (another name for cicada urine), we set off for the next university site, an area where students learn about planting. A statue of the Virgin Mary welcomed visitors and we admired some of the beautiful plantings and their seeds that were attracting plenty of insects.

   

 

We then left to make a quick stop at a park called Los Cusingos, that we would visit at length later; this was just a quick bathroom break before we took to the road again. My photo of the gray-headed tanager was not that great but you can see how beautiful the red passionflower (Passiflora vitifolia) at the entrance was.

As we drove to a place called Las Nubes, we passed private homes with their filled metal framework trash bins in front, a cemetery and plenty of banana plants.

 

   

One of our group members stepped in an anthill when trying to avoid puddles and traffic, which led to some stinging bites. In the meantime, others were trying to see various species of birds that were staying low in the vegetation along the road. I spotted a rather large wasp nest in a nearby tree, likely of the Synoeca septentrionalis species.

   

 

 

At some distance, there was a yellow-headed caracara (Milvago chimachima) sitting on a branch. These raptors are about 16-18 inches in length (41-46 cm) and part of their diet is carrion. They also eat reptiles, amphibians and other small birds, while avoiding birds as food. They take ticks off cattle as well, which gives them a thumbs up from me – any bird that eats ticks is a friend.

 

A gorgeous smooth-billed ani (Crotophaga ani) was sitting calmly as we milled around in the road. Some people might find this bird homely, but I think it is quite handsome despite a somewhat bulbous beak. They, too, are on my “good birds” list as they sometimes eat ticks and other parasites off of grazing animals. Another nice characteristic is their communal child-raising strategy – several pairs cooperate to build a nest together, in which several females than lay their eggs. They share the incubation and feeding of nestlings – hippies of the bird world!

 

We traveled on and the views along the road were beautiful, with the mountains and valleys in the distance and then we caught sight of some swallow-tailed kites (Elanoides forficatus) soaring over the nearest valley. We saw one land in a tree and it turned out that they were building a nest there. In the photo, you can see a small white patch on the right-hand side of the tree, which is the female kite on the nest.

As we waited patiently, a few kites began flying overhead; one with nesting material clutched in its claws.

 

They soared and swooped, giving us delightful views of their flight and then one came by with a meal that it had caught – a poor little chameleon or lizard.

 

We admired the Talamanca mountain range called La Amistad (Friendship), which separates Costa Rica from Panama. Starting in 1979, these two countries’ governments began a process to conserve the entire range, which is home to four indigenous groups of humans, 600 avian species, 215 mammal species, 250 species of amphibians and reptiles, 115 species of fish and some 10,000 flowering plants! As UNESCO has noted, this is: “one of the very few transboundary World Heritage properties, an excellent intergovernmental framework for coordinated and cooperative management and conservation.”

 

After a nice lunch, we continued visiting other sites, including one near a Canadian project. That afternoon, I saw my first trogon species – the gartered trogon (Trogon caligatus), another handsome bird to be sure.

 

      

While the rest of the group followed Steve’s instructions for sighting some birds hiding in underbrush on a slope, fellow traveler Janet and I watched some leaf-cutter ants (Atta cephalotes) at their labors. Sometimes, I was just not tall enough to see over shrubs to locate a bird and I love all wildlife anyway, so watching the ants in their industrious endeavor was fun.

On our way back to the lodge for supper, we passed small roadside stores and Steve spotted a fork-tailed flycatcher (Tyrannus savanna) for us.

 

 

Back at Talari, I did some sightseeing from the balcony of my room, spotting a lengthy and messy-looking flycatcher nest, a variegated squirrel (Sciurus variegatoides) traversing the tree canopy and a pair of palm tanagers (Thraupis palmarum), who were tending an offspring.

 

                       

At first, I thought the fledged bird was a different species as it sat under a leafy canopy, but later I saw the parents with it. Then it surprised Janet, who was staying next door – she called me over to see the fledgling who had flown into her room and was sitting in the middle of the floor.

   

She also had two nests under the roof of her balcony, one of which definitely belonged to a clay-colored thrush (Turdus grayi).

   

After admiring one of the neighbors’ cows and social flycatcher (Myiozetetes similis), I caught sight of a quiet beauty sitting on a branch in front of my room.

  

 

The Lesson’s motmot (Momotus lessonii), also known as the blue-diademed motmot, has a bright red eye and beautiful tail with what some birding sites call a “raquet tip”.

 

As we set off for the dining area, we were treated to a visit from a streaked flycatcher (Myiodynastes maculatus), quite a good-looking bird with its heavily streaked back, breast and face.

  

As we passed through some vegetation before dinner, I saw a gorgeous flowering banana as a blue-feathered and red-legged honeycreeper (Cyanerpes cyaneus) flew high overhead.

   

Even though we often were looking for birds in dark and leafy/shady areas, I avoided using a flash but when I saw the lemur anole (Norops lemurinus) on a tree, I gave in so that I coul d get a photo.

 

As dusk came on and we looked out from the dining area, we got to see some fiery-billed aracaris (Pteroglossus frantzii) in the distance.

 

 

While some others in our group got to see one close up, that was not my fate, but the next morning, the aracaris were in a little better light though still far away, allowing me to get a bit better photos.

 

   

We ended our second night at Talari Lodge with an owling outing – Steve managed to draw in a tropical screech owl (Megascops choliba) by playing its call on his phone. The owl who came had had an injury to one eye, with a pupil that would no longer dilate but s/he seemed to be flying fine and looked healthy. That bird gave us a nice long look at its beautiful self so that we retired for the night with a feeling of birding satisfaction!
