Mitchell Jarrett and I walked Cook's Trail from Sandy Creek Nature Center to the Oxbow wetland and back this morning. Again, no late migrants, but good numbers of winter birds with a couple highlights being a juvenile WHITE-CROWNED SPARROW and an ORANGE-CROWNED WARBLER, both along the snaggy section of the long boardwalk. The Orange-crowned Warbler was feeding high in the canopy, which is really weird for them in the fall/winter. I tried to turn it into a late Tennessee, but it definitely had no yellow towards the front and a yellowish wash on the undertail coverts. Other fun things were 2 Blue-headed Vireos, 3 Brown Creepers (heard only), 15 Winter Wrens, 32 Golden-crowned Kinglets, 30 Ruby-crowned Kinglets, 8 Hermit Thrushes (heard only), 2 Common Yellowthroats, 10+ Swamp Sparrows, and 75+ White-throated Sparrows. There were hoards of sparrows on our first pass up the boardwalk, but on the way back they had disappeared, and a pile of male Cardinal feathers had mysteriously appeared...
