    “Did you know birds have language?” I was asked this question by a friend who was relatively experienced in the outdoors—a successful big-game hunter and hiker of fourteeners. I was surprised. Of course bird calls mean something, but she had been to some recent outdoor training and the idea that birds communicated was a revelation.
    Most bird calls are territorial—essentially, the bird is telling other males to “bug-off” while providing a “come-on” to stray females. Learning calls is a great way to find and identify birds. In the spring and early summer that’s the best way to find birds. You can walk along and, for some common birds, hear the next one on territory and the next and the next as you walk along a trail.
    But what about in the fall when birds aren’t on territory? How do you find migrant warblers if they aren’t singing their characteristic, territorial songs? One of the best ways is to listen for chickadees. In a patch of aspen woods that I know well, I hear chickadee territorial calls in the spring and then I don’t hear the birds at all. They become furtive while nesting. Once it is autumn, however, the woods are either silent, or there is the incessant nasal “de-de-de” emitted by a group of black-capped chickadees.

    My question was “how do you find migrant warblers?" What does that have to do with chickadees?  Simple, chickadees are active and noisy. Usually, their calls serve the purpose of telling the rest of the group “I’m here.” “Now, I’m here.” “Now, here.”But, if a hawk is spotted or a noisy human, the calls become strident. The chickadee alarm call is well-known to most people, and it certainly is to other birds. So, it makes sense. If you are a migrant warbler having just flown in from Canada or Montana, attach yourself to a group of local chickadees. They know where to feed. They make plenty of noise so you can stay with the group in unfamiliar terrain, and they collectively sound the alarm if there’s something amiss.
    Back to the walk in the woods…it is quiet…nothing singing, nothing moving. Then you hear some chickadees. Check it out. Here they come—often 4 to 6 or more, just talking away. The trick is not be entertained too much by the chickadees hanging upside down and flitting quickly from bush to bush. Instead, look for the other birds in the flock. They are there. On a recent walk, I saw orange-crowned, yellow-rumped and yellow warblers with a flock of chickadees.
    Another flock had only a large group of Wilson’s warblers—the little guys with the black cap that breed in Colorado’s high mountains and further north into Canada.

Any time of year it is worth checking out a group of chickadees. Several of our year-around residents also travel in chickadee flocks—especially downy woodpeckers and white-breasted nuthatches.

Every fall and spring, groups of Colorado Mesa University students arrive on the Audubon Trail. Many residents know this trail as a nice paved trail for biking, walking, and running, but it is equally unknown to many residents and students, somewhat due to it being nestled behind the Albertson’s parking lot at the entrance to the Redlands. As part of CMU’s Biology 101 General Human Biology Lab, an introductory course designed for students not majoring in Biology, students participate in several field trips to expose them to plants and animals in their local environment, as well as relevant local biological issues.

Regardless of which semester students take the course, the Audubon Trail provides a plethora of opportunities to learn local plant and bird species. Professors use this trail to explain the importance of riparian habitats, which line waterways and provide important habitat for plants and animals that you do not find in drier habitats, such as on top of the Monument. As the class walks along the trail, occasionally hopping out of the way of a bicyclist using the path, professors point out different plants and trees that are native versus invasive, the types of seed dispersal used by different species, and general characteristics to identify each species. The Russian olive tree, for example, is an invasive species that was originally introduced from Russia and other parts of western and central Asia to North America. Because it has outcompeted native riparian plants and trees, it is considered invasive, and it depends on birds to disperse its seeds. By explaining the tales behind the plants, students get a better appreciation for the plants around them, as well as the types of plants that are important in different types of habitats.

Classes like Biology 101 Lab enable all of us to open our eyes to the details around us that we may pass every day without ever thinking about.  

Beyond being a great trail for exercise and pointing out riparian plants, there are many bird species one can find in just a short walk along the path. The best time to visit is in the spring because migrating birds are arriving and building nests for the breeding season. In the beginning of the fall, however, many species can still be seen before they migrate south for the winter, and of course, resident birds are reliable as well. A few species that are often found along the trail include robins, house sparrows, starlings, and many LBJs (little brown jobs). If you walk along the water, you may see mallards, wood ducks, swifts, and several species of swallows. The highlight for many during the spring, however, is seeing the great horned owl in her nest with chicks.

This particular female has been returning to her nest for many years. Two years ago, wind knocked one of the three chicks out of the nest, which incited a community effort of wildlife professionals and bird lovers alike to construct a sturdier nest for the owls, and to rehabilitate the injured chick. Usually when I take my students down the trail to see the nest, I pass one or two people along the way who also know of the owl and ask how she is doing.

For the students, many have never seen a great horned owl before, or any owl for that matter. Last year, I brought out a spotting scope to give the students a closer view than that provided by their binoculars. It’s one thing to look at an owl through binoculars, it’s another to feel up close and personal as you see each feather blowing in the wind, and feel her staring straight into your eyes. The students loved it, and I had to take a few looks myself.

As we looked at the female, we could see two chicks in the nest with a third probably tucked further down. There are many attractive animal species in the world. In my own research, I usually manage to study species whose young, if viewed through binoculars, tend to send a shiver down my spine. I won’t say that owl chicks are ugly, but they definitely are unique and share a certain gruff look that one wouldn’t want to mess with. After everyone had a chance to see the owl, we headed back to the van at the trail entrance before heading back to campus.

My hope with every passing semester is that the students realize how much beauty is around them all of the time, not just in the vistas from the Grand Mesa or the Colorado National Monument, but also along the paths they walk every day. I hope that after taking the 101 lab, they see many things with new eyes and their curiosity remains a life-long attribute.

I entitled my last blog “With a Capital H,” in order to highlight the importance of habitat protection if we are to maintain and enhance wildlife enjoyment opportunities. But habitat protection won’t happen if the next generation isn’t interested. This blog, as with the previous, was prompted by the recent Colorado Parks and Wildlife Northwest Region Partner Appreciation meeting held here in Grand Junction. Initially, the discussion focused on how the various groups could and should work together but very quickly, the conversation morphed into how best to involve Youth.

No matter how much habitat we save now, if the next generation isn’t interested, it won’t matter. Every group at the partnership meeting expressed the need to involve youth in outdoor activities. Virtually every group had, with money or volunteers or both, contributed to some effort to educate or introduce young people to the outdoors. 

 For more than a decade, Grand Valley Audubon Society (GVAS) has sponsored an outdoor education program for elementary school children. Cary Atwood, GVAS Education Chair, has done a remarkable job of organizing this program year-after-year. Here is her plea for volunteers for this year’s program:

          Early riser? Like to walk? Want to see birds up close? Wish to volunteer for a good cause? WE NEED YOU!

          Volunteers are needed during our Monday-Friday Bird Banding season beginning Sept. 20, ending October 19th. Any day you can help walk the net run areas with the bird bander and other volunteers would      be a great help. Net runs begin about 7:30 am and continue until nets close @ 11:30 a.m. If you would like to help in this scientific enterprise, we could use your help any morning! Please call or email Cary Atwood, Education Chair or 970 201-9651.
     Volunteers are also needed to conduct hour-long discovery nature walks with groups of 4th grade students who attend this field trip. If you love working with kids and their teachers, as well as helping connect kids to the great outdoors, please contact me for more details at the above phone or email address. Many thanks!!.

This photo is of an American Redstart captured last year. This is a very rare bird in our area and a few children were lucky enough to have a very close view of it. 

 Even if you can’t volunteer, plan on making a visit to the Grand Valley Audubon Banding Station. The Public Day will be held on Saturday, October 5th, from 8am until noon, although you are welcome to visit anytime. A State Parks Pass is required for entry. The banding station is located at the Kingfisher parking area near the restrooms within Connected Lakes State Park.

In the early days, Grand Valley Audubon only provided volunteers but as budget cuts and “teaching to the test” have taken hold, the cost is now $6000 or more to support the program—mostly for the buses because the School District is unable to provide them. Colorado Parks and Wildlife and Rocky Mountain Bird Observatory also contribute significant effort to the success of this activity. Additional funds are needed. Tax-deductable contributions for the program may be sent to Grand Valley Audubon Society, POB 1211, Grand Junction, CO 81502.

Once again, if you would like to volunteer or know more about the program, please contact Cary Atwood at This post provided by Nic Korte, Grand Valley Audubon Society.

Recently, I attended the Colorado Parks and Wildlife Northwest Region Partner Appreciation Meeting held here in Grand Junction. I am always interested in such meetings because they bring together some diverse uses of the outdoors. How much does Grand Valley Audubon Society have in common with the Rocky Mountain Elk Foundation? How much does the Mule Deer Society have in common with Grand Valley Anglers? Well, there is much more in common than not. A primary issue on everyone’s mind is Habitat.

Here is some damaged habitat:

Note the bare cutbanks eroded because of over-grazing. The stream that remained might once have held fish, but was now intermittent as the erosion has caused straightening and downcutting.
Further up this trail, an hour or two later, the canyon narrowed and there was a fence preventing livestock entry and we came upon this view.

I also remember finding Cordilleran Flycatchers and a couple of kinds of warblers nearby. It is consistently true that habitat that is good for birding and other wildlife viewing is also good for hunting and fishing.

My family has some property adjacent to the Grand Mesa National Forest. This property had been heavily over-grazed. Once we removed the cattle, kept the fence fixed, and removed invasive weeds (opportunistic plants that quickly colonize damaged soil), numbers of ground and shrub-nesting birds such as Swainson’s Thrushes and Lincoln’s Sparrows increased. We also began to see more scenes such as this one from a few weeks ago.

This is not to say that these photos of elk and deer can’t be taken on grazed land, but careful management is critical if we are going to preserve and, perhaps, improve our wildlife enjoyment opportunities. The habitat equation includes many factors such as roads and OHV use, energy development, and zoning. Issues involved are scientific, political, economic and always emotional. For these reasons it is important for all groups with an interest in the outdoors to work together.  This post provided by Nic Korte, Grand Valley Audubon Society.

Similar to birds, many butterflies have imaginative names. These can be useful if you have friends who may tease you for sneaking around in the woods looking for butterflies. Just tell them you are looking for satyrs. According to Greek Mythology, satyrs were half-man/half-beast creatures that loved wine and women and were always ready for physical pleasure. So, why not add to your outdoor enjoyment by going out and trying to find one. Sadly, you won’t find the satyr of mythology but you might find a Satyr Comma as in the photo below.

   Looking for and identifying butterflies is great fun. What do you need? Well, just like birding, you need a pair of binoculars and a field guide. A pair of close-focusing birding binoculars, something like 8 x 42 will work well. Many birders use 10x rather than 7 or 8. Because butterflies are small and close, the lower power is a bit easier to use.
   I would also add, “Take your camera.” Butterflies often permit a close approach. That way, when you arrive at home, you can compare your photos to those in the field guide. Because I’m such an amateur and often, in the field, cannot tell a fritillary from a checkerspot; the photos give me time to look for field marks and figure out what I’ve seen.
   For a field guide, I like Butterflies Through Binoculars: The West by Jeffery Glassberg. The introduction to this book answers the question “Why take up butterflying?” It will “…increase the time you spend in mountain meadows filled with flowers and encourage you to hike in breathtaking desert canyons in the springtime.” “Well,” I thought, “I really don’t need more encouragement to spend time in the outdoors.” For me, it is the added enjoyment of understanding more about nature with the added bonus that butterflies, unlike birds, are often most active at mid-day when birds are sleeping off their early morning activity.
  In a previous blog (, I included a photo of a pale swallowtail, probably the most abundant, large butterfly in our area—easy to see in your backyard—so that’s a good one to know. Once you know one or two, your eyes will adjust to picking up those fluttering flights and you may see a Red Admiral.

My last photo is of a Gorgone Checkerspot.


These three species were all found in Mesa County. Seeing them, photographing them, and, finally, identifying them added to the enjoyment of some recent mountain hikes.
