The birds seemed more active today than they have been for a couple of weeks. In particular, the Winter Wrens singing almost constantly, the Northern Waterthrushes more vocal, and more Canada Warblers sounding off. Once again I spent an hour chasing a bird around, convinced it was a Cerulean Warbler, only to find a Black-throated Blue - who came very eagerly to a Cerulean call and ignored the BT Blue song. Bird was in an area of tall mature oaks, with no conifers anywhere close. Here's the song that gave me fits: https://www.dropbox.com/sh/exlzs5q6jiuywif/AAA9VXhVAJvv1CFL-x4LL2L3a?dl=0 Boston Hollow/Yale Forest, Windham, Connecticut, US Jun 10, 2017 7:15 AM - 2:15 PM Protocol: Traveling 7.0 mile(s) 63 species Turkey Vulture 2 Red-shouldered Hawk 2 Broad-winged Hawk 3 Red-tailed Hawk 1 Mourning Dove 10 Ruby-throated Hummingbird 2 Red-bellied Woodpecker 1 Yellow-bellied Sapsucker 6 Downy Woodpecker 1 Hairy Woodpecker 1 Northern Flicker 1 Pileated Woodpecker 3 Eastern Wood-Pewee 5 Acadian Flycatcher 2 Least Flycatcher 6 Eastern Phoebe 10 Great Crested Flycatcher 5 Blue-headed Vireo 4 Warbling Vireo 6 Red-eyed Vireo 15 Blue Jay 10 Tree Swallow 2 Black-capped Chickadee 12 Tufted Titmouse 6 Red-breasted Nuthatch 2 White-breasted Nuthatch 1 Brown Creeper 1 Winter Wren 2 Blue-gray Gnatcatcher 2 Veery 20 Hermit Thrush 4 Wood Thrush 1 American Robin 15 Gray Catbird 12 Cedar Waxwing 12 Ovenbird 20 Worm-eating Warbler 1 Louisiana Waterthrush 4 Northern Waterthrush 7 Blue-winged Warbler 2 Black-and-white Warbler 10 Common Yellowthroat 10 American Redstart 1 Blackburnian Warbler 7 Yellow Warbler 12 Chestnut-sided Warbler 15 Black-throated Blue Warbler 3 Pine Warbler 8 Yellow-rumped Warbler 1 Black-throated Green Warbler 12 Canada Warbler 7 Chipping Sparrow 15 Song Sparrow 3 Eastern Towhee 9 Scarlet Tanager 6 Northern Cardinal 5 Rose-breasted Grosbeak 2 Red-winged Blackbird 1 Common Grackle 1 Brown-headed Cowbird 15 Baltimore Oriole 8 Purple Finch 2 American Goldfinch 12 View this checklist online at http://ebird.org/ebird/view/checklist/S37516493 Don Morgan Coventry, Ct
