My avian quest took me to Blenkinsop Lake today just as a storm rolled in. Fortunately, I was able to get a couple of photos of this bird before the rain really hit. Although the pictures are pretty blurry due to the poor lighting, the brilliant yellow throat and sides are striking. I didn't notice a yellow rump, but it was probably obscured by the wings in its perched position.
