The Very Very Late Ruby-throat

I

I strolled around the turrets of Hogwarts Castle, enjoying the sweeping views of tropical foliage. From the ravine below, a hummingbird came into view. It was large--something along the lines of a Violet Sabrewing. I reached out and held the bird. It seemed to be in some kind of transitional plumage: purple, mixed with buff and green. Then I was startled by sounds of an uproar coming from Hogwarts. A group of boys rode some kind of magical escalator, screaming with laughter. The bird vanished. Beautiful singing of pygmies (or Solomon Islanders) woke me. That's because my alarm plays CDs; this morning, it's Deep Forest's controversial 1993 album, Deep Forest.

Wondering what I had eaten the night before to produce such a vivid dream, I finished up my morning chores and headed to work without a moment to spare. As I headed for the gate Tuesday, Nov.15, an unmistakable silhouette  popped up into the sweet gum tree--a hummingbird! I ran back to the house for my binoculars. Like my dream bird, the hummer had vanished and I headed for work.

I posted my report of the hummingbird on MObirds, the listserve of the Audubon Society of Missouri. I also contacted my friends Lanny Chambers and Margy Terpstra. Margy lives nearby. She and her husband are wild bird photographers. They have a wealth of subjects in their beautiful, wildlife-friendly yard. Lanny is a hummingbird bander who has visited my yard many times chasing fall hummers. He also holds the record for the only Allen's Hummingbird in the state--banded in his own yard!

I didn't return up till after dark on Tuesday. Wednesday morning the temperature on my back porch was 33 ° F. The bird bath had a skin of ice, but I caught a brief view of a dark bird at the nectar feeder. Surely this is some rare stray! Wed. evening that I saw the bird again, and was shocked to see that it looked exactly like a male Ruby-throated Hummingbird! Ruby-throats are the only hummer normally present in our area, but they should be gone by October 10 or so. Males migrate earlier than females and juveniles. I don't remember ever seeing one after mid-September.

I didn't get to study the bird long before the light was gone. That's when I checked my email to find Margy's wonderful photos of Lanny examining the bird in hand. It was indeed a male Ruby-throat. It may not be the latest Ruby-throat ever, but it's likely to be the latest confirmed record. As you can see in the photos, he is a worn individual. His weight was good however, and Lanny saw no reason that the bird would have trouble migrating to his winter home in southern Mexico or even Panama.

I spotted the bird again Thursday and Friday mornings and evenings, still visiting the last of my Big blue sage (Salvia guaranitica) and Mexican bush sage (S. leucantha). The sages and the bird had weathered near-freezing temperatures for 3 nights. Saturday we warmed up to 60°, but I didn't see the bird. Let's hope that soon he'll be rubbing shoulders with Violet Sabrewings. Thanks to Margy Terpstra for the use of her photos and to Lanny Chambers for enabling us to play a role in the study of hummingbird migration.

Last Kite of the Season

Mississippi Kite's keystone-shaped tail shows in this silhouette composite photo by George Thomas

I may have seen my last Mississippi Kite of the year yesterday. My puppy Chunk and I visited Emmenegger Nature Park, climbing the trail along the bluffs above the Meramec River and paused at one of the glades. Chunk investigated the scents along and under the limestone rocks. I scanned the wide valley below with my binoculars. The landscape is urban, with remnants of oak-hickory woods on the hills. Floating over the former site of the Chrysler plant, a beautiful male Mississippi Kite sailed on the warm, still air. The open glade afforded me a rare view of the kite from above. Contrasting with the dark grey body, I could see the white head and secondaries—the flight feathers close to the body along the trailing edge of the wing.

I see Mississippi Kites almost daily in my area, starting in early May. They can be hard to spot early in the season. They tend to be silent and avoid being conspicuous as soon as they begin nesting. A friend who has a nest nearby said she often sees them flying low—under the radar, so to speak—as they approach the nest.

By August, the young are in flight and I occasionally hear them call. It's a strange sound—imagine a flycatcher impersonating a Broad-winged Hawk's two-note whistle. Click the play button to hear the recording below, also Creative Commons. Kites show up predictably at favorite perches around the neighborhood; always on dead snags atop mature trees. About 3 weeks ago I saw a group of 6 kites, including at least 2 juveniles, in a half-dead oak. Not far away, I could hear a 7th bird calling. Sometimes 2 or 3 will circle overhead. Are these local birds or the first migrants? I wish I knew.

When I first started birding seriously, in the early 90s, I saw my life Mississippi Kites in Webster Groves. Birders at that time said Webster was about as far north as they were found in summer, but now they breed up into Iowa.

They are predominantly insect eaters, so they must head south in fall. Conventional wisdom says that all the kites will be gone from Missouri by the end of the first week of September, but curiously, the first are record of Mississippi Kite was in autumn, on September 22, 1956 (Birds of the St. Louis Area; Where and When to Find Them, Webster Groves Nature Study Society, 1995). They migrate through Texas, along the east coast of Mexico, through Central and northwestern South America. Their non-breeding range is Bolivia, western Brazil, Paraguay, and northern Argentina. See this range map on the Cornell U website. Check out this spectacular video of a flock of kites migrating through Soberanía National Park in Panama, taken by Dave Jackson in April, 2007.

Bittersweet

American Bittersweet AMcC

Spring is a time of easy metaphors for renewal, hope, life. Autumn, well, not so much. Lovely fall colors are cheery, but brief. Just as Goldengrove is unleaving, a magnificent vine is revealed, covered with clusters of small, shiny red fruits, surrounded by open capsules of orange. We call it American Bittersweet, Celastrus scandens. Kurz notes in Shrubs and Woody Vines of Missouri that Celastrus is a Greek name for a tree and scandens means climbing. But how did it get its melancholy English name? Perhaps its autumnal display associates it with the demise of summer, the season of loss.

We humans like to ascribe meaning to natural phenomena. The albatross symbolizes guilt; the raven, death; the lark, “blithe spirit;” bittersweet, remembrance.

The contradictory name has been on my mind, since the furry friend you see in my profile picture died this week. For those who have experienced the death of a dear pet, I don’t need to explain my feelings. For those who have not, I don’t think I can adequately describe it. Instead, I’ll focus on the sweet memories.

Rosie and I went everywhere together for more than 16 years. She accompanied me on many birding trips, though she really preferred chipmunks, moles, and other mammals. She camped with us in the Rocky Mountains one June, and I was surprised to see her barking at two Gray Jays. She didn’t usually pay attention to birds. Then I saw one dart in and snatch a bit of her fur while the other stole a kibble from her bowl.

Rosie the Fishin' Dog AMcC

My brother-in-law called her “the fishin’ dog.” Her favorite spot was the tiny pond in my back yard. I keep a few goldfish there to eat mosquito larvae, and once she spotted them, she wanted them. She tried to catch a fish every day of her life and never succeeded. Far from being discouraged, she came back to the job fresh every time. She spent so much time in the water that one summer I had to take her to the vet for swimmer’s ear.

Like a true a terrier, she was independent. She seldom asked to sit in my lap as I watched TV, but she did like a good nature show now and then, especially if there were bears to bark at. When she was a puppy, she sat up on the bed while I watched Turner and Hooch; starring the tidy detective Tom Hanks and the untidy Dogue de Bordeaux named Hooch. She barked and jumped and generally went nuts every time Hooch came on the screen. That video was like a Jane Fonda exercise tape for Rosie.

If you grow bittersweet in your woodlot or on an arbor, be sure you get the native variety, not Celastrus orbiculatus, Round-leaved or Asiatic bittersweet. The fruits of Round-leaved bittersweet are less showy, and the plant is aggressive. As the name suggests, the easiest way to determine if the vine is native to the US or an invasive invader is the shape of the leaves. American bittersweet’s leaf is not round, but an elongated oval with a pointed tip. Sweet as they are to look at, the fruits are poisonous.

Fragrant Sumac in the Winner's Circle

Fragrant Sumac shows great fall color AMcC

If there were a triathlon of Midwestern native plants, Fragrant Sumac (Rhus aromatica) would be in the winner’s circle.

In the first leg of the triathlon, Wildlife Use, sumac’s performance is outstanding. Fragrant Sumac is one of the earliest blooming plants in our area (Midwestern US). Small yellow flowers appear in March, which, according to the US Forest Service, are pollinated by native bees. The red, hairy little red fruits are gobbled up by mockingbirds and others, since it is one of the first fruits available in summer. Caterpillars of the Red-banded Hairstreak eat fallen, decomposing sumac leaves (Brock and Kaufman, Butterflies of North America). I have seen this butterfly in my yard, but have never observed the caterpillar among the leaf litter.

Sumacs are host plants for two spectacular moths, both with outlandish caterpillars. The Showy Emerald Moth (Dichorda iridaria) caterpillar mimics a crumpled, dead sumac leaf. I haven’t seen this caterpillar yet, and I was unable to find a photo of one online, but nature-lovers should get a copy of David Wagner’s Caterpillars of Eastern North America just to see it. The adult Showy Emerald moth is beautiful. According to ButterfliesandMoths.org (hosted at Montana State University), its range centers on Missouri.

The startling Hickory Horned Devil can be almost 5 inches long! ButterfliesandMoths.org lists its food plant is “sumac.” It’s the larva of the Royal Walnut Moth, also known as Regal Moth. I haven’t seen these on my plants yet, but I’ve seen the adult moth nearby.

Fragrant sumac is a contender in the Garden Use leg of the competition. It’s a small shrub, drought-tolerant, native to glades and prairies. Dave Tylka recommends it as a good shrub for the understory of your wildlife garden (Native Landscaping for Wildlife and People). More than 10 years ago I purchased several plants of the variety named Gro-Low, named a Plant of Merit by Missouri Botanical Garden. It has formed a thick groundcover, just like I’d hoped it would. However, my plants have never borne fruit. Even though the Garden shows it with fruit, I think it is a sterile hybrid. Recently I bought three unimproved plants from a native plant nursery. They bloomed well their first spring and immediately bore fruit. In addition, I decided to experiment with a variety named ‘Konza Prairie,’ selected from the wild by the Kansas Forest Service for “its superior fruit production.” I think the natives have better fall color too, which leads me to the final leg of our triathlon.

We’ve had a good fall for leaf color this year, though not perfect. According to Missouri Environment and Garden, Oct. 2010, (newsletter of the University of Missouri’s Plant Protection Programs) the best fall color occurs when days are warm and nights are cool. We’ve had too many warm nights in October and November this year for optimal color, but it’s still been great. The first picture above is one of my “unimproved” fragrant sumacs and its purple leaves show that the anthocyanins have done their job. In the interest of full disclosure though, there is one plant that may outrun my little Rhus aromatica—its cousin, Smooth Sumac (Rhus glabra). This small tree has tropical-looking leaves that are dazzling red in fall. I may have to add it to my collection.

A big shout out to my Flickr friends Tom Woodward and Cherie Priest for the use of their Creative Commons photos!

Binoculars for Your Nose

Eastern Witch Hazel is the last tree to bloom in the Midwest. AMcC

I stepped outside on a calm autumn night last week. A fresh, citrus scent was in the air. It reminded me of witch hazel in bloom. That couldn’t be, of course, because my big hybrid witch hazel (Hamamelis x intermedia ‘Arnold Promise”) blooms in February. Then I remembered my other witch hazel tree, a scrawny little guy, completely overshadowed by big brother Arnold and my neighbor’s silver maples. When I bought my home in the 1980s, I knew I wanted a witch hazel tree. I was in love with the one that bloomed by the east wall of the Missouri Botanical Garden in late winter. I knew there was a native variety, but I wasn’t aware of any native plant nurseries in my areas at the time. I ordered Eastern witch hazel (Hamamelis virginiana) from a native plant nursery in the Appalachian Mountains and planted it about the same time as the Asian hybrid. According to Don Kurz’ book, Trees of Missouri, I ended up with a tree that is native to the Ozarks, though not to St. Louis County, Missouri. Two short decades zipped by with only the puniest of blooms, on the slenderest of twigs. Now this fragrance in November…

The next morning I confirmed it; my skinny 12 foot-tree was covered in bloom! The scent is wonderful, but it can be elusive. You can stand right next to a branch in full bloom and not be aware of it. You can be twenty feet away in the dark and know it instantly. Like all scent, it’s hard to describe with words: something like an orange, but lighter. I say full bloom, but that’s “full” by witch hazel standards. The petals are narrow ribbons of yellow, half-inch-long or a bit more. The blooms are often clustered together, without stems. 

With a shovel and a bit of determination, it’s not too hard to remake your perennial border. It’s a little tougher to remedy mistakes with trees and shrubs. If I were to remake the trees in my yard, I’d give my Eastern witch hazel a spot with more light, farther away from it’s winter-blooming relative. Both are covered in golden leaves in fall. One is the last tree of the year to bloom; the other is the first. 

According to John Hilty’s website, “Illinois Wildflowers,” Eastern witch hazel is pollinated by flies, but also a few moths, wasps and beetles. The plant doesn’t need showy petals, streaked with guides to direct butterflies and honey bees to the goodies. It does need scent, and so do I.

Scent may be the most neglected of human senses, but it’s more important than we admit. Grocery store shelves are filled with scented candles, scented oils, scented gel sticks, scented night lights, and scented trash bags. A popular fabric softener comes in 23 different varieties. On their website, you can search by “scent type”: “airy fresh” or “modern exotic.” 100 ml. spray bottles of perfume (3.4 oz) can sell for $100 and up. Gas stations sell air fresheners too. They say “New Car Scent” just flies off the shelf. Fragrance is of the essence in the garden for both humans and pollinators, as I mentioned in “Creatures of the Night.” It might be nice to have a device to amplify our sense of smell. Binoculars for your nose, perhaps?
