Everyone recognizes bird-watchers by their binoculars. Bird-listening, on the other hand, takes nothing more than your ears, and attention to Nature’s sounds. Listening for bird songs, then, may require your concentration at first, but soon it will become second nature. Some common birds of Utah are more easily found and known by their song than their appearance.
The Canyon Wren is one of my favorites. Its song is unique in North America. This tiny cinnamon-brown bird weighs little more than a marshmallow, but it belts out a cascading song big enough to reverberate off the rocky cliffs and slopes that are its home. You may not see the canyon wren, but try conversing with it by whistling its song in reply. I listen year-round for its song throughout Utah and our neighboring states, particularly in mid-elevation canyons.
Bird song can help you distinguish related bird species too. On the Great Plains, both Eastern and Western Meadowlarks co-occur. The plumage of these two starling-sized species is nearly identical, but their songs differ dramatically. The eastern species sings but a few clear notes, but our western meadowlark sings a beautiful musical warble.
Meadowlarks reside here year-round, typically in grassy areas, pastures and foothills. Their backs are brown, but the male’s chest is a brilliant yellow the color of fall aspen leaves. Males are frequently seen singing atop a fence post. Hearing a meadowlark always makes me smile, they seem so cheery. And that is another reason for listening to birds, for the sheer enjoyment of their song.
In the months to come, we will bring you more of Kevin Colver’s fine bird recordings to enjoy, interpret and learn. These are music lessons that everyone can enjoy!

Native Mourning Dove Courtesy USFWSDuring the winter after most doves have migrated, you may notice a dove foraging along the roadside or perched in a tree. A new species has arrived in our neighborhood, the Eurasian collared dove or Streptopelia decaocto, which has a distinctive black neck ring and a broad tail.
Originally found near the Bay of Bengal in Asia, this dove began its range expansion in the 1600’s. By 1900, it had made its way to Turkey, and by 2000 could be found as far north as the Arctic Circle in Scandinavia. Expansion into North America occurred in the early seventies when the collared dove appeared in the Bahamas. Since 1982, when first discovered in Florida, it has been gradually making its way north and west. Nineteen ninety-seven marked the first official report of Eurasian collared doves in Orem, Utah. Now they have spread throughout the state.
Eurasian collared doves join rock pigeons, the English sparrow, and the European starling as non-native birds that have expanded across the country. Experts attribute the success of Eurasian collared doves to the wide availability of seed offered by backyard bird feeders, as well as their ability to aggressively defend feeding areas. Some fear that they will cause territory or breeding problems for our native mourning dove, but so far there is no evidence to support this concern.
In an effort to reduce the number of Eurasian collared doves, the Utah DWR allows year-round harvesting. But be careful: don’t confuse this dove with the smaller mourning dove, which has a narrow, pointed tail and no ring on its neck. Eurasian collared doves have a distinct neck band and a broad, squared tail. Their calls also differ.
The mourning dove has the familiar melodic call:
[coo-ah cooo cooo coo]
[Kevin Colver, Songbirds of the Rocky Mountains

Now listen to the Eurasian collared dove:
[“coo-coooo-coo”, “coo-coooo-coo”, “coo-coooo-coo”, “krreair”]
[Eurasian collared dove – From Kevin Colver’s private library
Two calls combined for this piece.]
The verdict is still out on the impact that the Eurasian collared dove will have on native species. In the mean time, let’s watch to see how this new dove adapts to the neighborhood and fits into the ecosystem.
Thank-you to Lyle Bingham of Bridgerland Audubon for writing this essay and to Kevin Colver for providing the recorded songs.

In the name of curiosity and hunger, man has tracked the migrations of animals for centuries. The first record of the use of leg bands to track birds is from 1595 when one of Henry IV’s Peregrine Falcons was lost in France. It showed up 24 hours later in Malta, about 1400 miles away. John James Audubon tied silver cords to a brood of phoebes and identified two nestlings that returned the next year. In 1899, Hans Mortensen added identification numbers and his return address to the plain leg bands and modern bird banding was born.
In the United States, anyone who finds a bird band is encouraged to report it to the Patuxent Wildlife Research Center in Maryland. Banding provides us with limited information, however. There is no data about the bird’s life between the time of banding and its recapture or death.
But recent miniaturization of satellite transmitters used to track larger animals is now proving valuable in bird research. In 2006, Bridget Olsen of the Bear River Migratory Bird Refuge and Adrian Farmer of the US Geological Survey started placing tiny satellite transmitters on the backs of Marbled Godwits, a hefty sandpiper that rests at the refuge during its migration. The Marbled Godwit is in decline throughout its range. This large shorebird was chosen by scientists from Mexico, the United States and Canada as the focus for an international shorebird conservation effort.
The solar-powered transmitters periodically record the bird’s GPS location. The transmission is picked up via satellite and returned to the researchers. Comparing two transmissions indicates travel time and speed.
Olsen and Farmer work with wildlife officers across North America to track the Marbled Godwits from their wintering grounds in Baja California, through their migration to nesting grounds in the Great Plains, Alaska and Canada.

Holly: Hi, I’m Holly Strand from Stokes Nature Center in beautiful Logan Canyon.
Depending on where you are in Utah, fall is just around the corner. Or it may already be here. That means it’s time for many of our Utah birds to migrate south to warmer temperatures and more abundant food sources. Here in Logan Canyon, we’re getting ready to bid farewell to our charismatic little friends, the hummingbirds.
Hummingbirds are a New World phenomenon, living only in the western hemisphere. They are primarily tropical. Of the 330 species we know about, 95% live south of the US-Mexico border. Ecuador has 163 species–more than any other country. Colombia is next with 136 including a new species discovered just 5 years ago. Hummingbirds are known by a number of different names in Spanish including the generic term colibrí, picaflores meaning flower pickers ; and the more poetic term, joyas voladores or “flying jewels.”
In spite of its great size, only 16 different hummingbirds regularly found on the North American continent. Interestingly, –except for the Ruby-throated Hummingbird—all of these species breed west of the Mississippi River.
In Utah—roughly comparable to the size of Ecuador—5 species are regular visitors. Broad-tailed hummingbird and the black-chinned hummingbird are the most common and most widespread. They both overwinter in Mexico.
The calliope hummingbird is also seen in Utah. It is the smallest breeding bird in North America weighing about as much as a penny! The calliope is also the smallest long distant migrant bird in the world traveling up to 5600 miles in a single year. The rufous hummingbird is another long distance migrant seen in Utah, traveling from as far north as Alaska all the way down to central Mexico .
There is some controversy over whether or not you should continue to feed hummingbirds in fall. Some say you should quit feeding by late August or the hummingbirds won’t migrate. This is not true– in fact many hummingbirds begin migrating when their natural food sources are still intact. According to Audubon Society website, in the fall, you should keep your feeders up for two weeks after you see the last bird using it. The tiny birds need to double their body mass before migration, and a bit of extra nectar can only help.
