Nest monitored under permit as part of a long-term population monitoring program. Unusual substrate and placement, and slightly unusual structure.
In Ashe Juniper and oak woodland.
3 songs in about 35 seconds. Shortly after, a male landed about three feet from me, hopped around on several branches seemingly eyeing me, then left.
Did lower ash grove trail (only trail currently open) with very few birds; 90% were seen from parking lot and primarily in first few hundred feet after exiting parking lot on right side
