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.

    “Rare Bird Alert” is the title of the most recent album from the grammy-winning bluegrass band: Steve Martin and the Steep Canyon Rangers. Yes, it is that Steve Martin—the former “jerk” and “wild and crazy guy,” who was a recent headliner at the Telluride Bluegrass Festival and star of the recent movie “The Big Year.” If you are reading this blog, you probably know of “The Big Year,” the movie based on the best-seller by Mark Obmascik which chronicled the efforts of three birdwatchers attempting to break the record for most bird species seen in one year within an area (mostly the contiguous United States) designated by the American Birding Association. Many non-birders enjoyed the book and movie because the characters, their lives, and the competition are compelling and, at times, very funny.
    Most bird-watchers are not that obsessed with numbers of species seen and enjoy the beauty and lives of birds as much or more than simply seeing a new species. But, the movie is hilarious to most birders who see themselves arising in the pre-dawn hours to search for owls or racing out into bad weather to chase a rare bird after seeing a report on the internet. Martin’s introduction to bird-watching acquainted him with the term “rare bird alert,” so he used it for his next album.
     The three protagonists in The Big Year were always checking “rare bird alerts” so they could chase after an unusual species and, hopefully, find it without their rivals seeing it as well. I spent the last week with family in San Diego and, I admit, the first thing I did was check the local “rare bird alert,” in this instance, a Yahoo-group called SDBIRDS. I was delighted to learn that the day before, a lesser sand-plover (aka Mongolian Plover) had been seen in Imperial Beach--~25 minutes from where we were staying. So, I spent the first afternoon of our “family” vacation with a couple of birders from Massachusetts, one from the bay area, and several locals viewing the lesser sand-plover. How rare was this bird? My copy of Birds of Southern California rates the likelihood of seeing area birds. Those most likely to be seen are designated as “Hard to miss.” The lesser-sand plover did not even make the grouping called “Cosmic Good Luck.” This was the first record for San Diego County.
    Seeing rare birds is a lot of fun. There’s the excitement of seeing a species that may not return for decades and it is enjoyable to meet other excited and like-minded people. When a bird is really rare, such as San Diego’s lesser sand-plover, you don’t have to search for the bird. You look for the spotting scopes. That’s what I did. I showed up at the marsh and saw groups of scopes in three different locations—all aimed at the lesser sand-plover. Indeed, my first view was through someone else’s scope before I even had mine set up.

In Western Colorado, we have a yahoo listserve similar to SDBIRDS. Ours is WSBN (western slope birding network). Just log on to to sign up and receive all local reports or to check it from time-to-time to find out what local birders are reporting. A statewide rare bird alert is maintained by the Colorado Field Ornithologists ( This post provided by Nic Korte, Grand Valley Audubon Society.

   Where would you go to see brightly colored birds? Somewhere in the tropics, right? Generally, yes—but here in Western Colorado we can claim some of the most beautiful blue birds in the Americas. Those who know Central and South America might be saying: “Wait a minute. What about turquoise cotingas and some of the honeycreepers?” Well, yes, they are beautiful and blue but just try to find one of those cotingas. I’ve been bird-watching in the tropics many times and I’ve only seen the usually-rare cotingas three times and only briefly. The honeycreepers are easier to find, but they are small and often bouncing around high in the forest canopy permitting only brief glimpses.
   If you want to see beautiful blue birds, Western Colorado is a great location. If I remember correctly, it was the pioneer author Mary Austin who referred to mountain bluebirds as ’’flecks of fallen sky.” It is easy to be poetic about this common bird which can be seen almost all year on any drive to Grand Mesa, up Unaweep Canyon, even along interstate 70. Typically, we have a few around our valley all year. This is the male of a pair that nested in one of my birdhouses near Collbran this summer.   


In our pinyon-juniper forests, especially where they transition to some oaks and aspen, the Western Bluebird is easy-to-see. It is a deeper blue than its cousin, the mountain bluebird, and sports chestnut-colored shoulders.


A smaller, strikingly-colored bird that is mostly blue is the lazuli bunting which might even visit your backyard bird feeder. Here is a photo of the beautiful male. These are also fairly easy to see in the oak/pinyon/juniper complex. Females of all three of these species are less brightly colored—especially the bunting—so for your fix of “blue,” you need to see the male.

   Other blue birds that live and breed locally, and topic for a future blog, are three of our jays. And, in case you missed it, check out Jackson Trappett’s excellent photo of a blue grosbeak in a previous entry (

  Being blue has interested scientists for some time because red and orange pigments in feathers come from diet, but blue pigments that are eaten are destroyed with digestion. It turns out that blue is a structural color (as opposed to a pigmented color) because it’s generated by light interacting with a feather’s 3-dimensional arrangement. Different shapes and sizes of these arrangements create different shades of blue. You can read all the details here: . This post provided by Nic Korte, Grand Valley Audubon Society.

Here Come the Orange Hummingbirds (Good News and Bad News)

By Nic.Korte
Thursday, July 4, 2013

   Most folks have seen a bright orange flash around their hummingbird feeder or maybe out hiking.  These are rufous hummingbirds.  Before getting to the good news/bad news; consider their strange life history.  Have you ever thought it unusual that they show up about the first of July?  They don’t nest in Colorado.  Indeed, they are on their way back from as far north as southeastern Alaska. They breed further north than any other hummingbird.  Their US breeding range is essentially confined to Oregon, Washington, Idaho and Montana.
   This story so far should strike you as very odd.  If they are on their way back, why didn’t we see them on their way north as we do with the sandhill cranes and many shorebirds that show up in the spring and again in the fall?  Rufous hummingbirds migrate north up the Pacific coast shunning the intermountain West. Only on their return trip do they pass through Colorado.   And, why are we only seeing bright adult males? 
   As with all hummingbirds, males have only one role in breeding—impregnating the females.  That done, they head for home but somewhere in their evolutionary history have developed the unusual practice of migrating in a circuit.  All of this is why the first birds you’ll see, showing up in very late June or early July, are only adult males.  The females are still busy with their domestic duties but the males are headed back to Mexico where the species spend most of their lives. Females and juveniles will be coming through later in July and in August.
   The good news is they are a beautiful little bird.  I’ve been lucky enough to see 60 or 70 species of hummingbirds (which, by the way, are only found in the Americas—more about that in an upcoming blog.)  So, I’ve seen hummers with names like mountain gem and jewelfront, and coquette.  As striking as many of these are, the male rufous is a contender for most handsome.

   My photo doesn’t it do it justice.  The gorget, if seen perfectly in the sun, is a scintillant orange-red while the body is a shiny rufous-orange—although some are green-backed.  So, that’s the good news.  This beautiful bird is back again to brighten our yards and feeders.  They are also endearing to many people because of their fierce reputation.  Often they will successfully chase the local hummers (bad news for them) away and take command of a feeder. 
   The bad news, for me, takes two forms. On a personal level, they are a sign of summer waning.  It may only be July, but here’s a Northern migrant headed home. Can this much-anticipated summer season be slipping away already?  Can fall be far behind?
   The worse news is that National Audubon Society scientists estimate that the global population of these amazing flyers (1000 miles without food or rest has been recorded) has declined nearly 60 percent in the past three decades.  My first encounter with them was in Northern Arizona about 30 years ago.  There were dozens among a field of pink beeplant—a sight I’ll never forget.
   I will probably see them in my yard this year, but my memory tells me that formerly I saw two or three and had one every day for several weeks.  Not so anymore.  A couple of years ago, I didn’t’ see any in my yard.  
We have some mountain property where up to 30 hummingbirds may show up at our feeders. I can count on the rufous being there again this year—but not so many as ten years ago. 
  What’s causing the population decline? According to the National Audubon Society: “A deadly combination of habitat destruction, toxic pollution and the spread of invasive plants. And now a new threat may overshadow them all: ecological chaos caused by a warming climate. Warmer weather prompts earlier flowering of nectar-bearing plants that hummingbirds rely on during their epic migrations. If the flowers are gone before the birds arrive, they may starve.”  (This post provided by Nic Korte, Grand Valley Audubon Society.  Send questions/comments to]To learn more and to participate in the activities of Grand Valley Audubon, please see our website at and “like” us on Facebook!])
