As of today, 23 June, it is confirmed the the nest at the Bank of the West building was unsuccessful again this year. We inspected the nest from the top of the building and there were no nestlings or eggs in the nest box. There was one adult bird in the nest box, who later was most likely identified as Annie/Andie the male that has been in Fargo for the past 3 years. Below is a picture of the bird that appears to be Annie.
