So the other day I heard the blue jays making their jay noises. I hear them sometimes, but not enough to consider it normal, so I often check on what’s going on when they start their calling. Not long ago they alerted me to an interesting standoff between a  hawk and a couple of doves. This time, however, all I noticed were the jays in the tree. I turned to go inside when I saw a small bird in the branch closest to me. I stood still, barely breathing, and it turned full circle to let me see it’s yellow undersides, dark gray back and black necklace. I also took note of its white eyering. We stared at each other for a while, then it flew off to the other side of the yard. I flew into the house and found my Sibley’s Guide. I knew it was a warbler because of the shape and beak. I looked at the prothonotary warbler first, because I thought that is what it was, but the prothonotary warbler doesn’t have the black necklace. After browsing the guide for a while I decided I’d had a Canada warbler in my yard — although the back seemed too dull for the breeding male and even the female. They are migrating now, so I think I saw a Canada Warbler, but if you have other suggestions, let me know.
