Mother chipmunk and pup snuggling on a rock at Great Basin National Park. The pup was probably weaned but still attempting to nurse. Not sure what particular type of chipmunk this is.
There were several active Barn Swallow nests around the Great Basin NP visitors center. "Nest with young" is the highest level of breeding confirmation on Ebird and it was a pleasure to add these records to the Ebird breeding bird database.
Commonly seen and heard as they fly about at dusk, I found two Common Nighthawks sleeping on juniper limbs along the Mountain View Nature Trail.
Three geographically separated species of bristlecone pine are found across the western United States. These are among the oldest organisms on earth with some individuals living more than 5,000 years. They grow just below treeline in isolated groves and their wood is extremely dense and resinous, protecting the tree from insects, fungi, and other diseases. While other trees decay and rot, bristlecones are more like rocks, slowly eroding with exposure to wind and sand and snow.
Sky Pilots were among the more common and attractive alpine wildflowers. They grew in tight clusters amid the rocky scree.
There are half a dozen very similar species of Greater fritillary (Speyeria sp.) found in Great Basin National Park. Unfortunately, the most informative features for separating the different species of Speyeria involves the patterning of the underwing, a feature I missed when photographing this individual.
Quite a few Sagebrush Lizards were seen along the Mountain View Nature Trail loop.
