[EBB Sightings] Grasshopper Sparrows at Sibley

There were no fewer than four singing Grasshopper Sparrows at Sibley
Volcano Regional Preserve this morning. At one point, two males seemed
to argue about property lines and chased each other. Later, a male sang
from a thistle and his mate showed up with nesting material, then dove
underneath that thistle. So quite likely that's a nest site.

Rufous-crowned and Lark Sparrows were also about.

Bird vocalization was non-stop till noon when I left.
