Between 3ish and 5ish near the aforementioned Baird's location (in fact, end-to-end on Drennan Road), we had:
Cassin's Sparrows (our highlight)
Lark Sparrows
Vesper Sparrows
Song Sparrows
Clay-colored Sparrows
No Ammodramus, Grasshopper nor Baird's
Lark Buntings
Horned Larks
Harrier, Red Tails, Scaled Quails, dozens of Nighthawks overhead on the ride home near Elbert, etc.
Beautiful afternoon of birding and riding, minus the target.
