Great Basin National Park with Soldiers2Scientists: Round Two!
/by Ned Bohman
This was the second year that Great Basin Bird Observatory joined Soldiers2Scientists (S2S) for their EcoRecon Expedition to Great Basin National Park. Soldiers2Scientists is a nonprofit organization founded in 2013 that connects veterans and active-duty military members with conservation, and outdoor recreation opportunities. Through partnerships with national parks, conservation organizations, and scientists, S2S gives veterans the opportunity to contribute to meaningful research while building connections and continuing their service in a new way.
The Great Basin EcoRecon expedition brings veterans to the park to participate in a variety of ongoing conservation and research projects. S2S has partnered with Great Basin National Park for several years, working alongside park staff and organizations like GBBO to collect data on everything from wildlife and aquatic ecosystems to forests and caves.
For more background on the project and how our partnership got started, check out my post from last year (2025)!

This year, volunteers from the Reno and Carson City birding communities joined us, allowing us to survey a few more plots than we did last year. We collected data from plots near the Lehman Caves Visitor Center, as well as several plots in Snake Creek Canyon.
Late summer typically marks the beginning of pine nut harvest for Pinyon Jays. As pinyon pine cones ripen, the jays collect and cache the seeds, building up food stores that will sustain them through the months ahead. The timing and abundance of cone production can vary considerably from year to year, creating a cycle of abundance and scarcity that shapes the lives of both pinyon pines and Pinyon Jays.
In years when pinyon pines produce abundant cone crops, known as mast years, Pinyon Jays have access to the resources they need to build food caches, survive the winter, and reproduce. When cone crops fail, however, the jays may have to travel much farther in search of alternative food sources. These movements can sometimes bring them into areas where they aren't typically observed.
Before we even began our surveys on day one, it was clear that this was not going to be a year of abundant pinyon nuts. As I made my way around camp, I couldn't find a single ripe cone. By this point in the season, the cones should be ripe or very close to it. Instead, most of the trees were barren. On some, we found small numbers of clearly aborted cones, while others held only brown, opened cones left over from previous years.

I had also made several stops along the Highway 50 corridor on my drive to the park and was similarly unable to find any fresh cones. As the other volunteers arrived, they echoed what I had seen. There was little evidence of this year's pine nut crop anywhere we looked.
With the jays' primary food resource for this time of year seemingly absent, we wondered what the birds would be doing instead…

The jays we observed were mostly moving around in small groups, calling to distant, unseen birds. Our surveys in Snake Creek Canyon took place in closed-canopy woodland at elevations where we would expect Pinyon Jays to be harvesting pine nuts. But, of course, that was not the case this year. We observed birds flying between trees, perching prominently, and calling to other jays flying nearby. It is possible that they were searching for food and communicating their observations to other members of the flock, although we cannot know for certain from these observations alone. We saw very similar behavior at our survey sites near the visitor center, which were slightly lower in elevation than the Snake Creek Canyon sites.
We did eventually catch up with a group of Pinyon Jays on the valley floor a few miles east of Snake Creek Canyon. There, the birds appeared to be hunting insects as a group. Members of the flock flew low over the shrubs, while others swooped down to the ground, chasing and grabbing prey with their bills. The entire flock seemed to move almost like a wave, rolling across the tops of the shrubs as birds dropped down to forage and then took flight again.
Almost as quickly as they appeared, they were gone. We had simply happened to intersect their path, and it was clear that the flock was covering considerable ground. The behavior we observed offers a fascinating glimpse into how Pinyon Jays may adjust their movements and foraging strategies when their usual food resources are unavailable.

Although we saw no evidence of pine nut production this year, our time in the field still resulted in meaningful observations. Documenting the lack of ripe pine cones, for example, gives us important context for understanding what Pinyon Jays are doing on the landscape and how food availability may influence their behavior. A key strength of our community science protocol is its ability to help us identify relationships between habitat conditions and Pinyon Jay behavior. Collectively, these observations can help us better understand Pinyon Jay habitat use and provide valuable information to guide land management and conservation efforts.
A huge thank you to Soldiers2Scientists and all of our GBBO supporters for making this such a fun and memorable weekend!
