As a native of Virginia, I'm a new transplant to the Rocky Mountain State. I am a former Virginia Master Naturalist with dual degrees in English and Environmental Science and am a Certified Interpretive Guide with the National Association for Interpretation. I'm also currently enrolled in the Audubon Society of Greater Denver's Master Birder class. I'm keenly interested in the environment and fostering appreciation and respect for our natural world. I look forward to learning more about my new home and sharing what I know.

ID Challenge: Mountain vs Black-capped vs Carolina Chickadee

It’s a cold, grey, windy day today and my yard is awash in activity. My bird feeders especially are getting a workout with several new visitors this year, including a Mountain Chickadee. Mountain Chickadees aren’t uncommon along the Front Range, but they’re usually found in the foothills and mountains where there are an abundance of conifers rather than in my lower elevation deciduous-tree-dominated suburban neighborhood.

I was first alerted to my new guest by its scratchy “chicka-dee-dee” call, like a Black-capped Chickadee (a year-round resident in my neighborhood) with a sore throat. For comparison, here’s the Black-capped Chickadee’s call.

Other than their calls, Mountain Chickadees are fairly easy to differentiate from Black-capped Chickadees. The most obvious visual difference is the Mountain’s bold white eyebrow, which makes it a little angry-looking. The Mountain is also usually a lot greyer, with very little if any buffiness on the underparts and less white edging on the wings.

Although my area of Colorado is only home to Black-capped and Mountain Chickadees, the true ID challenge is between Black-capped and Carolina Chickadees. Carolina Chickadees are slightly smaller than Black-capped Chickadees and are more of a southeastern US bird. They were my backyard chickadee in Virginia.

Like the Mountain Chickadee, Carolinas are greyer than the Black-capped with little white wing-edging and not as much buffy coloring on their underparts. Their white cheek patch is greyer toward the back of the head and their black “bib” is smaller than the Black-capped with well-defined edges. There is also much less white edging on the outer tail feathers in Carolina Chickadees.

Probably the easiest way to distinguish between the Carolina Chickadee and the Black-capped Chickadee, however, is by voice. The song of the Black-capped Chickadee is usually a 3-note “Hey sweet-ie” whereas the Carolina’s song is usually a a 4-note song: “Fee bee fee bay.” The Carolina Chickadee also tends to have a faster call. But don’t worry, the two look-alikes only share territory in a small band roughly shown on the map below.

It’s that time of year again: Denver Audubon’s HOOTenanny has arrived! This annual event celebrating all things owl has been expanded this year from one day to five with daily, family-friendly programs on Tuesday, September 19th through Friday, September 22nd leading up to the big festival on Saturday, September 23rd.

Learn about the little-known owl constellation Noctua! Go on a night hike! Meet rehabilitated ambassador owls from Nature’s Educators! Listen to live music and get your face painted! All programming is held at the Audubon nature center at Chatfield except for Little Hoots story time, which is being held at the Roxborough Library.

Admission is $8 for adult members and non-member children (3-12), $5 for member children, and $10 for non-member adults. That’s pretty cheap for entertainment these days and your admission helps support the great educational programming provided by Denver Audubon.

More information, including directions to the Audubon nature center and how to register, is available on the Audubon Society of Greater Denver website.
