Wonderful set of photos as usual. What intrigued me is the photo of the Black-throated green collecting nesting material. I was at Ashbridge's last week-end and saw a female Blackburnian doing the same. So, I posted the photo of the Blackburnian female in another forum and asked about their nesting possibility there. I was told that they do nest around GTA but certainly not in isolated pockets along the lake. I guess it is just instinct and/or honing the nest building skill. Either way it is interesting to see this behavior.
