Presume Not the Common Robin

6 Replies

This time of year we observe a remarkable influx of American Robins in western Montana. True, the birds are year-round residents in small numbers through much of the state, but by April, instead of spotting the occasional bird, Braden and I begin counting them by the dozens. As much as I love this “thrush flush”, I have to admit it has led to some close calls in bird IDs this past week.

This time of year, it’s easy to assume that every medium-sized bird is a robin—but BIRDERS BEWARE!

Every morning I grab my binoculars when I head out to take our dog Lola for her morning tramp around our neighborhood. We follow a mile-long route around a school, down to a park, and then back up home, skirting the edges of houses, woods, and Rattlesnake Creek. Over the years, Braden and I have compiled a healthy bird list for the route, but I have to say that it rarely yields any real surprises. As a result, I become lulled into a sense of complacency about what I am looking at.

To wit, with all the robins around lately, I have naturally assumed I am looking at Turdus migratorius when I see medium-sized, nondescript birds perched in a distant tree. On my Wednesday dog walk, I again made those assumptions. I mean, there were a ton of robins about and I identified many by sight and sound. When I saw fifteen birds sitting in another tree, I thought, “More robins.” Fortunately, something made me pause—perhaps my inner birder conscience or a feather that didn’t look quite right. Ignoring Lola’s piercing eyes, which pleaded for me to throw the ball again, I raised my binoculars and found . . .

This photo sheds light—or shadow—on how easy it is to mistake other groups of birds for American Robins.

Cedar Waxwings! “Huh,” I thought. “That’s cool.” Waxwings weren’t earth-shattering, but I didn’t expect to see such a group this time of year. I threw the ball for Lola and continued walking, and a hundred yards later saw another group of birds in a tree. “More robins,” I thought, then remembered the waxwings and again raised my binoculars to find . . .

Evening Grosbeaks! Even better, it was my first good look at them for the year! Those two back-to-back sightings taught me a valuable birding lesson: never assume what you’re looking at just because certain birds are more common or you’ve seen them before. I hope it’s a lesson that will serve you well this spring—not that there’s anything wrong with robins.  

Up close, an Evening Grosbeak’s markings are distinctive, but even from medium range, light and shadow can obscure an accurate ID!

Camas National Wildlife Refuge Update

After last week’s post on our visit to Camas National Wildlife Refuge (see Pocatello or Bust), I received a welcome call from Refuge Manager Brian Wehausen. I had left a message with him, wanting to learn more about the seemingly bleak situation at the refuge, and he generously shared half an hour with me explaining the water shortage and prospects for the future.

When the refuge was purchased in 1937, Brian began, local farmers were taking water from the nearby Henry’s Fork stream and surface irrigating their crops in such a way that loads of excess water “skipped down” to the refuge, creating ample ponds for birds and other wildlife. When farmers switched to sprinkler irrigation in the 1980s, that load of water ceased and the refuge began drying up. “Before agriculture,” Brian shared, “the refuge probably had good and bad years, but we don’t really have any way of knowing what it was like.” Even so, the current situation has been impacted by the drop in the aquifer due to overpumping by agricultural and other interests so that in bad years such as this, migrating birds meet mud instead of water on their way north.

While offering little for migrating birds now, infrastructure improvements at Camas NWR will soon allow the refuge to fill at least some of their ponds even in bad years.

The good news is that the refuge recently received money from the Great American Outdoors Act to drill new wells that will put water into areas that they know retain it better. Brian doesn’t think they can return the refuge to what it was in its heyday in the 60s and 70s, but hopes to definitely improve the situation for waterfowl. “My whole goal,” he said, “is to be efficient with the surface water and also be efficient with the well water, and most of the water we pump will go right back into the aquifer.”

Unlike in some other places, the local community supports the refuge and agrees it’s worth keeping wet. “Generally, people love to see the birds,” Brian says. “We were a mecca for hunting in the 1970s, and that’s gone away, but people still come. Photography is our Number One use today.”

Before we hung up, I was curious what happens to the snow geese and other birds who arrive to find the refuge dry. Brian told me that when Camas is dry, Dillon (just over the border in southern Montana) also tends to be dry so most of the birds head straight up to Freezeout Lake (see our post A Real Wild Goose Chase)—which is where many birders are enjoying them as I write this. It sounds, though, that we’ll all be able to add Camas to our great birding hotspot lists in the very near future!
