It was Trey that just left after spending about 5-10 min on the ledge, scraping (or whatever it is that he's doing since we first saw it yesterday) in the gravel, but one of the boys was there when I logged back on about 40 min ago. He left as I was posting about seeing him and initially thinking it was the sister--so the ledge has has quite a lot of traffic in the past hour!
The biggest difference I noticed between Trey and his son while seeing them come and go this past hour really hit me when Trey arrived. He is definately white breasted and he gracefully and almost like floating, landed on the ledge. Also, there's space between his body and the ledge where you can really see his 'puffaloon' legs. I noticed that the son was brown and no space or leg was visible while he was in the same position as Trey was on the legde. (I know Trey can cover his feet too, but he didn't do that this last visit). Anyway, just thought I'd share what I observed because it really hit me just now!
