Sex, Age, Comment | Adult. Leucistic bird, which I'm pretty sure is the same as the one I found at same place last year. See 2301 for comparison. All leucistic parts are the same on both birds, and they both have the diffuse gray breast band, which normally is not a trait of this species. However, there is some variation to the level of whiteness between the two years, but I don't think it is enough to cause speculations about the two being different birds, or the last one being an offspring. If you look at the growing tail feather on 2301 you can see a white fringe to a part of the tip. Looking at the same feather of this year's bird, it has a similar white part, just more worn. Since none of the other tail feathers show any white, on both birds, in my opinion, it is a strong indication that the two is one and the same bird. The question then is if the tail feather is the same, or if a new one has grown completely out this year, which could be the case since the photos of 2301 were taken on June 11, and the one this year a month later. | ||||||||||||
