Bird vs. Window

Hi, I’m Holly Strand.

Every fall, I cringe when I hear the soft thumps caused by feathery bodies slamming into the windows of our house. Etched designs into the window glass do not seem to deter these miniature kamikaze pilots.

The most intense period of window strikes occurs when birds are feasting on our chokecherries and crabapples. The birds get intoxicated from the naturally fermented fruit and their judgement flies out the window—or rather, into the window. Robins, waxwings and other fruit eaters are the most frequent flyers under the influence.

Ornithologists estimate that in the United States alone well over 100 million birds are killed each year by window collisions. Many accidents occur when birds see trees, sky, or clouds reflected on a glass but do not see the hard transparent window surface itself. Sometimes the birds are merely stunned and recover in a few moments. Often, however, window hits lead to severe internal injuries and death.

Ornithologist Pete Dunne found that feeders placed 13 feet away from a window corresponded with maximum deaths. However, a feeder place within a meter of window actually reduced the accident rate. Birds focus on the feeder as they fly toward the window. If they strike the glass leaving the feeder, they do so at very low speed.

You can redirect the accident prone birds by putting up awnings, beads, bamboo, or fabric strips. Stickers or silhouettes will help if they are spaced 2-4 in. apart across the entire window. At our house, taping some reflective ribbon to the window so that it flutters in the breeze has been very effective.

If you find a bird dazed from a window hit, place it in a dark container with a lid such as a shoebox, and leave it somewhere warm and quiet, out of reach of pets and other predators. If the weather is extremely cold, you may need to take it inside. Do not try to give it food and water, and resist handling it as much as possible. The darkness will calm the bird while it revives, which should occur within a few minutes, unless it is seriously injured. Release it outside as soon as it appears awake and alert.

Heading South

US Flyways

Hi I’m Holly Strand.

Every fall, I scan the sky for the fluid lines of birds heading south to their winter homes. Although the flocks are fascinating to watch, I get a bit melancholy. I imagine the warm and balmy weather ahead of them and the frigid temperatures that are in store for me.

Migration behavior in birds –and other animals– evolved to help them cope with a scarcity of resources during a particular time of the year. Severe weather and lack of food are characteristic of winters in the far north of the Northern Hemisphere. Therefore almost all of the birds migrate. Although more hospitable than the arctic, Utah winters are no picnic. Therefore, birds that breed in Utah have also bought heavily into migration.

Looking at a map of Western Hemisphere migration routes –or flyways—you might be reminded of the route map of a major airline. There are short regional flights, say to an adjacent state to the south or sometimes just to a lower altitude. There are medium distance flights to Mexico or Central America. And then there are the long haul flights, with birds flying from northern tundra all the way to Argentina, Chile or Antarctica.

Wilson’s phalarope is one of Utah’s long-distance migrators. After the breeding season, about 500,000 birds form the largest staging concentration of phalaropes in the world at the Great Salt Lake. After fueling up on brine shrimp and brine flies, the birds head off to wetlands in Bolivia and Argentina.

Swainson’s hawk travels farther than any other North American hawk. It migrates to the Argentinian pampas in huge flocks with as many as 5,000–10,000 individual. If a Swainson’s hawk begins migration in the northern part of its range, total round trip distance will exceed 20,000 km.

The rufous hummingbird doesn’t breed in Utah but flies though on its remarkable journey from the northwest and Alaska to Central America. If you measure its travel in body lengths as opposed to distance, this tiny little aviator makes world’s longest known migration.

Species Names

Common Mullein

Copyright 2010 Holly Strand

Hi, I’m Holly Strand from Stokes Nature Center in beautiful Logan Canyon.

Common Mullein , Our Lady’s Flannel. Velvet Plant. Clown’s Lungwort. Jupiter’s Staff. Shepherd’s Clubs. Beggar’s Blanket. Hare’s Beard, Bear’s ear, and Nature’s Toilet Paper. These are just a few of the names that apply to a single species that is a widely distributed across Europe and Central Asia and naturalized in North America.

Common names are descriptive and often charming, but they are local names and won’t be understood beyond their particular region or in another language. And sometimes common names are downright misleading. For example a koala bear isn’t a bear. And a red panda isn’t a panda.

To avoid confusion, scientists use a unique two word designation—usually taken from Latin or Greek – to identify a species unambiguously. The first word is the name of the genus to which the organism belongs. The genus comprises a group of closely related animals or plants. The second term is chosen by the person that describes and publishes the species account.

It is a huge breach of etiquette to name a species after yourself. But the taxonomist can name the organism after the person who actually found it in the field. An example is Mentzelia shultziorum, a blazingstar named after Utah botanist Leila Schultz who first found the plant in Professor Valley in Grand County. Taxonomists can also name the species after a friendly colleague and then hope that the friendly colleague will name one after them.

Often the name will describe some physical characteristics of the species. Earlier this year, a paleontologist unearthed a new dinosaur here in Utah and named it Jeyawati rugoculus. That’s a combination of Zuni and Latin for “grinding mouth, wrinkle eye.”

Other names are based on location: Penstemon utahensis is a penstemon found in our state. Amblyoproctus boondocksius is a scarab, and was apparently found in the middle of nowhere.

Often the name will represent a subjective reaction toward the organism. Vampyroteuthis infernalis translates into “vampire squid from Hell”, Indeed it is rather scary looking cross between a squid and an octopus.

Some scientists get sentimental at naming time. They’ll name species after their loved ones. Or their favorite artists. Thus we have 2 trilobites in the Avalanchurus genus named lennoni and starri. McCartney and Harrison are honored in a neighboring genus.

I’m proud to say that a Utah biologist named a parasitic louse, Strigiphilus garylarsoni. The Far Side cartoonist should not take offense. In a letter to Larson, Dr. Dale Clayton praised him for “the enormous contribution that my colleagues and I feel you have made to biology through your cartoons.”

Birds of a Feather Bird Collective Nouns

Hi, I’m Holly Strand from Stokes Nature Center in beautiful Logan Canyon.

The word flock is a collective noun that refers to a natural grouping of any kind of bird.

Certain bird species commonly flock together to feed, to travel or to help defend themselves. Flocks are usually thought of as composed of just one species but mixed species flocks also occur. A mixture of species can take advantage of a variety of abilities to find food or detect predators.

When you are talking about a group of single species–birds of a feather so to speak– there exist specific and sometimes eloquent terms that can be used instead of the word flock. We’ve all heard the term “gaggle of geese.” But did you know that earlier this spring, we saw a “season” of tanagers come through the valley? I have never seen a flock of owls, but if there were one, we could call it a “parliament” of owls. More common than a parliament of owls is a “congress” of crows. You can also call this same group a murder of crows.

The word siege can apply to either bitterns or herons. A congregation may refer to plovers, egrets or ibises. A bouquet connotes warblers, hummingbirds or pheasants. However, for hummingbirds I prefer the collective terms shimmer or charm.”

Punsters might appreciate a seasoning of cinnamon teal, a chain of bobolinks a ladle of dippers or– my husband’s favorite—an outfield of flycatchers.

Sometimes, a bunch of birds in the water is different from a bunch of birds in the air. You’ll find a paddling of ducks in the water but a team of ducks flying overhead. Likewise a gaggle of geese is swimming, while a skein of geese is airbourne.

One collective phrase is so evocative that it became the title of an entire book on collective nouns for birds and other animals. In An Exaltation of Larks, (now in it’s 3rd printing) author James Lipton explains that many collective nouns were hunting terms that originated in the 15th century or earlier. Nevertheless, the collective terms are correct and appropriate for use today.

This Saturday, August 21st, experience a shimmer of hummingbirds with Stokes Nature Center. Our hummingbird program will take place just east of the Second Dam in Logan Canyon. Drop in anytime between 8-11am. Signs or people will direct you on where to park. For more information call the Nature Center at 435.755.3239.
