For the past little while, I've been scanning Common Goldeneye's in hopes of finally seeing a Barrow's. This happened just a few weeks ago and since then, I've seen them on a few occasions in the Saint John River. The first I found was a male in the sewage lagoon. It really stood out since I have been so used to just seeing Common's. I later found a few females (the different color bill stood out) and I'm hoping one is still around for the Christmas Bird Count here in Woodstock.
Here is a photo of the male I saw. Its not the greatest photo as it was at the far end of the lagoon, but its clear enough for a positive ID.
