I spent time in the area of The Falconer watching different sparrows. Feeling joy I headed north over Bow Bridge then up the hill towards the Gill. This appeared to the right. Flash of yellow. I had no idea what I was seeing. Click click,click, click, holding breath, mesmerized. A young fellow I'd never seen before came along. "Oh, good. You got the prairie." Time to do a dance. My first prairie warbler. Lots of birders saw it. I've got a lot of images to edit, but wanted to post this stunningly beautiful visitor to the park.
