On Friday during a lovely walk in Windfields Park at York Mills and Bayview in Toronto I saw and heard a couple of little warblers. I was able to identify a Black-throated Blue Warbler by sight and sound. I see that others have been spotted during the past few days. I thought I caught a Blackpoll Warbler, by sight and sound, but it might be a little early and I didn't see others in the reports. Anyone feel they can confirm or suggest what it might have been?
