I made the run up to the Spring Green Preserve-west SNA in Sauk County Wisconsin with hopes to see the beautiful Blue Grosbeak and get a life bird too. This uncommon bird for the state has been reported on and off all summer long at this location. I was not let down as it only took a few minutes to locate this bird by its distinct call. I viewed it multiple times on top of the tall white pines running east. I also viewed the bird from a distance on the short oaks northeast of the Pearl Road dead end. A few other birds to note were Eastern Towhee’s, Indigo Buntings, 1st summer male and female Baltimore Orioles which I thought they were Chats with the early morning sun hitting them had gold color like I never saw before. Images were taken on August 9, 2014.
