That's great Gord! They really are beautiful little birds and their song is so strong for such a diminutive creature. I just received a great photo of a singing male in the sunshine over at Grant Narrows in the Pitt Polder area so I guess they're moving through just now.
Found a possible 4 today, 3 positively and one singing in the distance. Warbler songs are sometimes subtlety different and now that I have hearing assistance I’m hearing a lot of birdsong that I have to relearn.
