Hundreds of yellow-rumps made it difficult to pick out other warbler species but they were there. These included >8 Nashville, a surprising (for me at least) 6 Orange-crowned, 1 Northern Parula, several Black-throated Green, 1 Palm. Other species seen were 1 Blue-headed Vireo, 1 Purple Finch, Field, White-crowned and White-throated Sparrows and both Kinglets.
All birds were seen just north of Colborne lodge on both sides of Colborne Lodge Dr.
