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.

My hummer summer, part 2 — beauty in flight, beauty at rest

ruby-throated-hummingbird-i77a8438-maria-de-bruynIn my previous blog, I mentioned that the ruby-throated hummingbirds (Archilocus colubris) had a greater variety of flowering plants to visit in my yard this year and that increased the size and diversity of their nectar buffet. The availability of multiple food sources also meant that they spent a bit more time visiting – they didn’t just dash to a feeder, perch or hover for a drink and then take off. They visited feeders, different blooms and took little rests between meals, giving me numerous chances to watch them and practice my hummingbird photography – a win-win for both us!

One of their favorite flowers were the lantanas (Lantana), which are also a favorite of mine as they attract many smaller pollinators such as bees and butterflies and are still profusely blooming in the latter half of October.

This year, several types of sage brightened my gardens. Some deep blue Brazilian sage plants (Salvia guaranitica), kindly donated to me by Gail, a fellow birder, added color and provided the hummers with deep blooms into which they could insert their long bills.

 

ruby-throated-hummingbird-i77a1315-maria-de-bruyn-res

ruby-throated-hummingbird-i77a7519-maria-de-bruyn-resA small-leaf sage (also known as Festival or little-leaf sage, Salvia microphylla “San Carlos Festival”) provided an ongoing splash of deep red blooms that attracted the hummers over and over again. This plant not only graced the garden in the summer but is still blooming profusely now, making it another one of my favorites. A couple other different red sages and a red beebalm (Monarda didyma) were good nectar choices but they didn’t bloom as long or in such abundance. Perhaps next year, they will have gained strength.

ruby-throated-hummingbird-i77a1160-maria-de-bruyn-resThe two stonecrop plants (Hylotelephium Autumn joy), in my front garden, with their rounded bunches of little pink flowers, had hummer visitors on a few occasions, but these are not one of their preferred blooms. The milkweed plants (Asclepias syriaca) also only had a few visits as far as I could tell.

And it was the same story for the blue balloon flower (Platycodon grandiflorus), which does get its fair share of bees.

 

 

 

ruby-throated-hummingbird-i77a2198-maria-de-bruyn-resI had planted cardinal flowers (Lobelia cardinalis), which unfortunately didn’t get any flowers. I did see a bird visiting this plant species near Bolin Creek, however. The same happened with a trumpet vine (Campsis radicans), but at a vine cluster near the Haw River I saw how they inserted their heads entirely into the tubular blooms.

In between feedings, the hummingbirds will perch to watch for intruders into “their space”. But they also will take sun-baths, pointing their faces upward and puffing themselves up.

They will then change shape, stretching their necks and spreading their wings and tail feathers to expose as much of their bodies as possible to the sunlight.

They may relieve themselves while they are in flight and then later take a little power nap of a few seconds.

Grooming is also a frequent activity – these little avians make sure that they stay just as beautiful as the sweet flowers that they frequent!

When the males turn their heads so that the light hits them in different ways, they do a nice job of demonstrating that their bright gorget colors are not in the feathers themselves but the result of prism cells in their feathers that change how the light is reflected depending on the angle we see.

ruby-throated-hummingbird-i77a6366-maria-de-bruyn-resWhen they’re done sun bathing, grooming and resting, the hummingbirds need to take off again. However, their feet are so tiny that they can’t walk and, when they lift off, they also don’t have the foot strength to push.  So they rise into the air using the power of their wings, quickly flapping as they set off and rapidly reaching their usual rate of about 50-53 beats per second.

ruby-throated-hummingbird-i77a7167-maria-de-bruyn-resMy last summer hummingbird residents appear to have left for their Central American wintering grounds on 7 October, just before Hurricane Matthew arrived in North Carolina. I really hope that they were able to get through the windy environment without problems as they began their long migratory journeys and I am already looking forward to seeing them arrive next spring. In the meantime, I’m keeping a couple feeders up in case another hummer species decides to over-winter here – and the Carolina chickadees (Poecile carolinensis), Northern cardinals (Cardinalis cardinalis) and tufted titmice (Baeolophus bicolor) can continue to use the ant guards over the feeders as their preferred watering holes.

 

A varied palate – hummingbirds’ choice of foods

As promised, one more blog on hummingbirds before I move to another topic; their presence always brings me enjoyment and I know other people who are enamored with these tiny birds, too. Also, although autumn has come, I still have a couple ruby-throated hummingbirds (Archilochus colubris) at my feeders. And a couple days ago I had the privilege of seeing a species new to me, the buff-bellied hummingbird (Amazilia yucatanensis), which has only visited the state of North Carolina once before (at least as far as human witnesses are concerned)!

DK7A2528© Maria de Bruyn resThe hummers have a varied diet, including mainly insects (mosquitoes, gnats, fruit flies, small bees), spiders, tree sap and sweet nectar (or sugar water). They tend to feed about 5-10 times per hour during the day and need about 10 calories of nutrition each day.

 

It is a lot easier to catch them drinking nectar than catching insects (apologies for the blurred photos)!

Hummingbirds use their long tubular tongues as elastic micro-pumps to obtain nectar. This enables them to lick a flower up to 20 times per second as they gather food. And although we can’t see it when just looking at them, they have forked tongues (like snakes)!

DK7A4497© Maria de Bruyn2The hummers visit a variety of flowers to drink their sweet nectar, often preferring orange or red flowers but certainly not avoiding others.In my garden, this includes cardinal flowers (Lobelia cardinalis), hollyhocks (Alcea), yellow passionflower (Passiflora lutea) and lantana (Lantana).

In nature reserves, I’ve seen them visiting morning glories (Ipomoea), ironweed (Vernonia) and trumpet vines (Campsis radicans).

Their long bills, tubular tongues and slim bodies make it easy for them to drink from long flowers, but sometimes they will simply pierce the base of a flower to obtain nectar, or use a hole already made there by an insect.

Light-colored flowers are not shunned as food sources, however!

Bean plants and gerbera daisies (Gerbera)  were on the menu at the Translating Traditions farm.

At my house, the hummers visit the nectar feeders with great regularity, presumably because the food is very easily available there. A little known fact about the hummingbirds is that, compared to all other birds, their brains are the largest in comparison to body size. They remember where feeders are from year to year and also can recognize the people who fill the feeders. When the nectar is low and I appear, a hummer will sometimes hover and chitter in my direction at length; I really do think it is warning me that it’s time to prepare another serving.

The buff-bellied hummingbird breeds in Mexico and south Texas. When they migrate, it is in a north-eastern direction, but the only previous recorded visit of one to North Carolina was in 2007. Now there is one hanging out at a couple’s home in the town of Winston-Salem, so I accompanied three fellow birders to go see it. Our 90-minute drive there was rewarded by a view of the bird within about 15 minutes and we stayed for almost two hours watching it come and go along with some ruby-throated hummingbirds.

These hummingbirds have bellies with a light orange-yellow hue, brighter orange tail feathers and a bright green back and head. In contrast to the ruby-throated hummingbird’s straight dark bill, they have a reddish, curved bill. These lovely little birds appear to be the least studied species among the hummingbirds in the USA.

Two years ago, I had a rufous hummingbird (Selasphorus rufus) visit my nectar feeder after he had migrated here in winter from the far North. This year, I’ll leave at least one feeder up again after the ruby-throats take off for warmer climes in case some wintering hummers need food. And I’ll look forward to seeing my regular residents again next summer!
