2020 Pika Patrol


Over the weekend, my husband and I went up to the mountains for the first time this summer. We’ve been trying to isolate ourselves, and the mountain trails have been busy with people trying to get out of their houses while being safe.

We headed up to do our annual Pika Patrol for the Denver Zoo and the Front Range Pika Project. (Pika Patrol, 2019 Edition) We both really enjoy these trips because they force us to get out away from cell phones and cars and the internet, and just be.

It was smokey as we stepped out of the car at the trail head. Colorado is in a drought, and we have four major forest fires burning in the mountains right now. There was a forest fire just west on the other side of the mountain — literally. It produced clouds of smoke that plagued us the entire hike.

But the hike started out well, in spite of the smoke. We were delighted to see these white columbines in the rocks at the side of the parking area. My trusty plant books say that white columbines are a normal, if rare, variation on our more common Colorado columbine.

We walked a few paces and found a nice group of beautiful traditional blue and white Colorado Columbines as well.

The trail up to the site we that we monitor is off of US 40 near Berthoud Pass. Starting at 10,500 feet, the trail is steep — a 50% grade, which means that for every 2 steps forward, we took one up. We did this for about two hours. Every year, I tell my husband, this is it. This is the last time we do this site.

This year, the hike was even harder due to smoke polluting the thin air.

Looking down from the talus to the meadow where pika gather plants for hay. Smoke from a forest fire on the other side of the mountain we are on covers everything from the alpine down the to the plains.

After plodding up the mountain, we reached the meadow that is the beginning of the pika observation site. Last year, as we approached, we could hear the pika’s squeaky-ball chirps. We did this year, too. But instead of a chorus, there only were a few isolated calls.

Instead, we saw chipmunks on the alpine tundra, something I have only rarely seen before.

We took a few minutes to dig out our data sheet, and start recording our observations. It was hot for the alpine — 75o — and so dry the plants crunched beneath our boots.

As we puttered around, we began to see a few pika dashing over the rocks. They went out to the nearby meadow, and came back with a mouthful of forage. But we didn’t find any hay piles yet. It may be too early — they still have a month or so before the snow usually falls.

Pika scat and trimmed plant stems. The leaves have been harvested to be put into hay piles.

We found a few places where the pika had left their scat, and collected some for DNA analysis by FRPP.

But compared to last year, there just weren’t many of the little critters around. We speculated on why there were not as many pika as there were last year. We came up with several possibilities:

  1. We came up a month earlier this year. The pikas may not be very active gathering forage for their hay piles yet.
  2. We came up a month earlier, and it was too warm for the pikas. While we were in the alpine, it was 75o, the upper limit of the temperature range that pikas can operate in.
  3. It was just too hot for them, and they had died.

We are hoping that it is either possibilities one or two, or both. But it was hot, and dry. Alpine plants are not tall, but they are usually green and lush. This year, they have taken a beating with the drought, and that will probably impact how much forage the pika can gather.

Even before we became concerned about the conditions we found at the pika site, we had planned to visit another pika site in the Upper Arkansas Valley (that hopefully won’t be so much of a death march). We’ll go up a month from now, when it is hopefully cooler. And we’ll hopefully see plenty of pika building plenty of hay piles for the winter.

  1. Lovely Columbine photos – my husband and I got married in Colorado and the Columbine flower was our color scheme 🙂 Be safe in the wildfires, we’re struggling with that here in CA too.

  2. Yeah, even with all the smoke and crunchy plants, it was good to get out. It is such an out-of-the-way trail that we didn’t see anybody else the entire day! Nice in spite of the dry.

  3. Keeping my fingers crossed it’s just early and nothing worse for a lack of seeing these little alpine cuties. Am going to enroll in rain dancing classes. Nearly 70 days of 90ºF temps so far. At this rate, we’ll see snow before rain. 🤞🏼Stay cool.
