Windy Mountain Shrub Ecosystem Hike

Windy Mountain Shrub Ecosystem Hike

With the leaf canopy of the big trees fill in and the baby Great Horned Owls fledged, my husband and I decided to take a hike in the foothills west of our house. This hike took us through the Mountain Shrub plant community — the boundary between the High Plains and the Ponderosa Pine plant communites. It’s often overlooked because it doesn’t have sweeping vistas of the plains or the towering trees of the forests. But it usually has a greater diversity of plants and animals than either of the other two.

Delicate purple to lavendar flower coming off a plant stem. The top petals form a hood and the bottom petals form a lip for insects to land on.

A lovely narrow-leaved penstemon was one of the first plants we saw.

Dozens of yellow ray flowers come from a center in an overlapping pattern. Orange-yellow anthers come out of the center of the arrangement.

Just a little further on, we saw this awesome plant in the sunflower family. I was so excited by it that I told my husband “This would look great in our native xeriscape garden!” When I looked it up on Plantnet, it said it was Nodding Brighteyes from someplace not on this continent. So I’d have to make an exception to my native plant motif, but of more concern, it has escaped cultivation and has the potential to become a problem plant. Sigh.

Small yellow flower has five petals. The top four are about the same size and are evenly spaced. But the bottom petal is twice the width of any of the others, and it has dramatic deep purple lines leading into the center of the flower, pointing the way for insects to find the nectar within. If you look closely, two of the upper petals have brushes with which to deposit pollen on the visiting insects.

Okay, to make up for it, we next saw a small plucky Nutall’s violet, worthy of any flower garden. Not a shrinking violet at all, this plant with the bright yellow flower survives in hot sun and dry soil. My kind of plant.

Slightly smaller than a robin, this bird has a sky-blue head, with a rust-red chest and white belly. It is perched in an evergreen juniper tree.

Just as we started up the trail, the wind picked up. It made getting a shot of this very shy lazuli bunting even harder. Sorry for the blur, but he was so colorful, I had to include him.

Blindingly white flowers with pure yellow anthers arc thorugh green leaves.

Gorgeous sand lilies were on along the trail going up and back. I always feel like it should be Easter when I see these little gems.

Blindingly white flowers with pure yellow anthers arc thorugh green leaves. The calyx tube from the petals to the base of the plant is four inches long.

I love how long the calyx tube is, running from the showy flower parts down four inches or so to where the seeds are made at the base of the plant.

A bird with a medium blue head, white chest feathers and black bill is perched on a twig.
A blast of wind has blown all the bird's belly feather askew.

Did I mention it got windy? I’ve never seen a bird’s feathers blow back like they did on this Scrub Jay.

A delicate five petaled flower. The petals are white with dark lines running towards the center of the flower. Each petal is split about a quarter of the way down, to give them a "mouse-eared" look.

A charmingly-named mouse-earred chickweed. To my great surprise, it is in the carnation family! Another one I could add to my native garden…

Small grey bird with a brown head is preening it's chest feathers.

A chipping sparrow had its feathers ruffled by gusts of wind and is preening them all back into place…

Small grey bird with a black beak and a russet crown perches on a twig. The wind has blown the feathers on the bird's crown straight up.

… only to have them mussed up again.

Small gray butterfly. The butterfly's wings each have a small orange spot on the, with black on the trailing edge.

Normally when we hike through the Mountain Shrub community, we see lots of butterflies. Today, this was the only one, and it seemed like it was clinging to the plant stem for dear life. Did the wind ground them? Very possibly.

I have never seen a butterfly like this before, so I ran it through iNaturalist. The answer came back that it was “a butterfly”. Um, thanks?

Big bright yellow flowers on top of a robust plant. The leaves each have three leaflets in a palmate orientation.

Golden banner, in the pea family. DO have this one in my native xeriscape garden. Love it.

Small gray bird with white underparts, and a white eye-ring. It's beak and tail are black.. It is perched in a tree. whose leaves are just budding out.

After two and a half hours of walking in the wind and sun, we were on the downhill stretch — literally. But I kept hearing a buzzing chirp that I couldn’t identify, so made my husband stop and stare intently at the shrub where the sound was coming from. After several minutes, I began to see something flit and buzz-chirp in it. It finally popped onto a twig where I could photograph it (sorry for the blur — windy, you know). But I couldn’t identify it. So I ran it through Cornell’s Merlin app (how did we identify ANYTHING before cell phone apps?) and it said it was a Blue-gray gnatcatcher.

I have never heard of a Blue-gray gnatcatcher before, and had no idea Colorado had gnatcatchers. Or that anybody had gnatcatchers. So here’s one for my life list! Yay!

  1. As always, a great flora and fauna show, Amy! I laughed out loud at the “it’s a butterfly” response. This is why I’m loathe to jump on the AI train.

    1. Ironically, to my knowledge, iNaturalist is all people behind the curtain. But it’s also quasi competitive, where you get more points for more answers, useful or not. The person who responded with “it’s a butterfly” was probably trying to climb the leaderboard. I got some better responses this morning. The photo I took is of a Gray Hairstreak, in the Gossamer-winged butterfly family. Now I know. πŸ™‚

      1. So quantity, not quality? That’s disappointing but glad someone pointed you to a better answer.

  2. Thanks for appreciating and sharing this special habitat, Amy!
    So funny about your generic butterfly ID! My brother and I laugh about an app that routinely IDs any vegetation as “Dicot.”
    Could it be a Grey Hairstreak?

    1. A few days later I got a better ID — they agree with you that it is a grey hairstreak. I love learning something new!
