and May-y dates
10% (la
Today at Grandview Cemetery (GC), Fort Collins (Larimer), I had a sapsucker
with a brown-spangled back, red cap, gray nape, and a two-toned red-and-white
throat. My first views (which did not include good looks at the throat)
convinced me this hyper, over-sugared individual was an early Yellow-
This morning there was a single White-throated Sparrow at the northern most
part of the Sanitas Valley trail, and a flock of Bushtits in the same area.
The sparrow was picking along the path that leads to the housing development.
