Tag Archives: Ruby-throated hummingbird

In anticipation of spring and your spring planting plans (and as I am sorting through mountains of photos, film footage, and text for the butterfly gardening show), I am planning a little series here on the blog. The focus is all about sharing information and photos about individual plant species that provide sustenance and shelter for the pollinators that grace our gardens.

Trumpet Creeper (Campsis radicans)

Two of our very favorite native plant species for attracting Ruby-throated Hummingbirds are the blossoms of the northern catalpa tree (Catalpa speciosa) and trumpet creeper (Campsis radicans), both of which belong to the Bignonia family. Catalpa trees bear white flowers with violet nectar guides and, despite their color differences, Catalpa blossoms and the red-orange flowers of trumpet creeper reveal several similarities, The reproductive structures are positioned inside at the top lip of the opening, surrounded by five asymmetrically shaped petals fused together. As the hummingbird pokes its head deep inside the trumpet-shaped blossom to extract nectar, the pollen-bearing sticky stamens and pistils attach to its forehead and transfer pollen from one blossom to the next.

Nectar volume influences the blossoms’ attractiveness to the Ruby-throated Hummingbird. The small florets of plants such as those of butterfly bushes and zinnias offer nectar, though they require many visits to make it worthwhile. Our native Campsis radicans produces one of the highest known volumes of floral nectar per flower. Hummingbird fledglings quickly learn from their mothers the blossoms that contain the most nectar.

Campsis radicans is found growing throughout much of the eastern half of the country. Unable to support itself vertically, it trails along the ground until it reaches a tree. Tiny aerial rootlets are formed to adhere itself to the surface of the tree to then allow it to climb skyward towards the sunlight. Unlike vines such as Chinese wisteria and bittersweet, which gird and then strangle a tree, trumpet creeper clings tightly. Campsis radicans is a very fast growing and top-heavy vine. It is unsuitable for anything but the strongest structure. As it blooms on the current year’s growth, it can be grown along a solid fence and cut back very vigorously in early spring.

For the intimate garden or garden room, where a less rampant (but no less hardy) grower is a more suitable choice, there are several hybrids of C. radicans with flowers that are as equally attractive to the hummingbirds. ‘Madame Galen’ (Campsis radicans x tagliabuana) flowers in lovely shades of apricot-orange. The newer cultivar ‘Indian Summer’ is described with the less persistent and dense growth characteristics similar to that of ‘Madame Galen’ and beautiful blossoms of apricot-orange with a deeper red eye.

The extended period of florescence of C. radicans corresponds to the span of time in which ruby-throated hummingbirds are living in their northern range. Like Chinese wisteria, trumpet creeper can take six years or more to flower from seed. Plant the largest specimen one’s budget will allow.

A BUTTERFLY BONANZA!

Recently I returned from a trip to southwestern Ohio to visit my sister-in-law Amy, who is recovering from hip replacement surgery. She is mending beautifully and determined to get back on her feet —only a few days after returning home from the hospital the visiting nurse said she was doing as well as their typical patient at three weeks out!

While Amy was resting I would grab my camera and head into her garden and the surrounding fields because here was a Butterfly and Hummingbird Bonanza! I encountered dozens of Ruby-throated Hummingbirds, typically feeding and frolicking in groups of threes and fours, and many differing species of butterflies. For the most part, the butterflies that I photographed are the same species of butterflies that are found on Cape Ann and throughout New England. Having no expectation of encountering myriad butterflies, in both range of species and in legions of each, I had not planned accordingly and only packed my Panasonic Lumix. I love this camera, but like all cameras it does have certain limitations. Lesson learned—that is to say—always travel prepared for anything to happen!

Amy is a working architect and, as time and her work schedule have permitted, she has (along with her recently deceased dear husband Tim) redesigned and restored her lovely old farmhouse and gardens. There are several cozy porches and a deck under construction in which to sit and observe the wildlife dramas that play out almost daily.

What makes Amy’s garden so inviting to the pollinators? The old farmhouse is approached by traveling down a crushed limestone driveway. On either side of the drive are fields, either overgrown with wildflowers, or maintained as mowed grass. The fields meet the forest edge. There are several neighboring houses along the drive but privacy is afforded because the houses are sited a fair distance apart and because there are naturalized arrangements of native trees and shrubs. Flower borders are planted in close proximity to her home and also further afield. Beyond the flower borders is a large vegetable garden, approximately twenty feet deep by sixty feet long, with a row of sunflowers bordering the back length and a cheerful patch of zinnias running along the fore edge. Beyond the vegetable garden is a vigorous crop of blackberries and beyond that is a clump of wildflowers, including common milkweed (Asclepias syriaca), which were covered in Monarch caterpillars, and the tall growing New York Ironweed (Veronia noveboracensis), which was in full bloom. All of these elements provide clues as to why Amy’s garden is a haven for the butterflies and hummingbirds. Additionally, adjacent to the house is an old peach tree, which bears great quantities of fruit. Because Amy has been under the weather from her hip injury she was not able to maintain the peach tree this past season. The peaches were falling to the ground and rotting—not really a bad thing as you will soon see—imagine the not intolerable odor of vinegary peach juice.

Yellow Sulphur

The combination of the atypically lengthy stretch of hot, sultry weather, punctuated by soaking rain storms, along with the salt and mineral-rich limestone driveway, flowering plants, wildflowers, surrounding woodlands that provide shelter and larval food for caterpillars, hummingbird feeders, and rotting peaches—all work in tandem to create a paradise for the pollinators—bees, butterflies, and hummingbirds.

Female Ruby-throated Hummingbird

In the morning I would find Buckeyes, Question Marks, and Red-spotted Purples drinking salts and minerals from moist patches in the driveway. Hungry families of Ruby-throated Hummingbirds were noisily nectaring from the flowers and feeders; one feeder is sited beneath the peach tree and the other about twenty feet away, under the lilacs, a hummingbird superhighway of sorts, with inviting nectar flowers along the route. The male and female hummingbirds are both territorial and, when encountering anything out of the ordinary (my camera and I, for example) will threaten by whizzing and whirling, albeit harmlessly, close to your head.

Common Buckeye

By mid-day the hummingbird and butterfly scene was full underway. Spicebush Swallowtails at the Rose-of-Sharon, tiger swallowtails, yellow sulphurs, Eastern Tailed-Blues, Monarchs, checkerspots, and angelwings nectaring at the zinnia patch, phlox, and lobelia, and most remarkable of all, were the number of butterflies that were drawn to the pungent lure of rotting peaches. By late afternoon dozens of Hackberry Emperors, Red-spotted Purples, Question Marks, and Red Admirals were to be found intently imbibing from the fermenting peaches, and by day’s end, I believe they were drunken butterflies, making extraordinarily easy subjects to photograph. I would be down on my hands and knees with the lens held so closely it was nearly touching them, and several times that did happen as they fluttered or hopped onto the camera’s lens. In the lingering remnants of late day’s light, the hummingbirds were there again at the feeders and flowers, and all manner of swallowtails in the wildflower meadow were nectaring from the New York Ironweed.

Red-spotted Purple

The three different species of butterflies in the above group of photographs have a unique relationship. The Red-spotted Purple and Spicebush Swallowtail (both palatable to predatory birds) are thought to have evolved to mimic the Pipevine Swallowtail (center photograph), which is highly toxic and foul tasting.

I was sad to say goodbye to my sister-in-law but glad to return home to my family. My unexpected yet welcome encounter with the butterflies of Southwest Ohio reminded me once again that butterflies are a symbol of transformation, joy, and beauty throughout cultures the world over. Perhaps Amy’s butterflies mirror the transformative journey to which she has embarked.
