I wandered about the Humber River valley, north of Nashville (in Toronto's northwest outskirts) today, to look for migrating warblers. Once again it was a beautiful day and the migrants seemed to be doing just that: migrating. If they came to ground, I missed them. It wasn't until I got home that I discovered this Black-throated Blue Warbler in the backyard. Quite striking and distinctive is this little bird.
