First full day in the Chiracahua Mts. Bill photo'ed the canyon walls at sunrise, followed by pre-breakfast birding at the Cave Creek Ranch feeders (Mexican Jay, and brief glimpses of Blue-throated hummingbird) and into the desert scrub (paired Curve-billed Thrashers, a Cactus Wren and Canyon Towhee). Most of this day was spent along the road between Cave Creek Ranch and the Southwest Research Station, checking out campgrounds, picnic areas and trails. The best flock of the day came along the trail beyond South Fork picnic area - bridled titmice, painted redstarts, grace's warbler, black-throated grey warblers, and a brown creeper for spice.Special moments of the day: Bob locating the beryline hummingbird nest (per instructions) and finding a female beryline hummer re-constructing her lichen-covered nest with multiple trips to neaby nest material sources. Walking up past bug collection sheets at the Research Station to call in the Whiskered screech owl for an actual visual sighting of this little owl.
