Spent an hour scanning Gregory Canyon road and the trailhead on this cold evening.
First sighting was a very cooperative Virginia's warbler on the
roadside thickets, scouring the leaves for bugs where he periodically offered terrific views of his handsome orange crown for 20 mins. He was seen again in the same thicket when I returned an hour later.
Also of note and just up the road were two MacGillivray's warblers, 1 Dusky/Hammond's flycatcher, 1 Blue-gray gnatcatcher, 2 Wilson's warblers, 3 Orange-crowned warblers, 3 Ruby-crowned kinglets and of course a host of Chipping sparrows.
Lots of fun out there!
