your right and some people have a gift, earlier in the year a good friend of mine whos a top flyer came to me for a visit.
He walked into the race loft and pointed straight at my best racing hen which had just won the previous week and the week before and said what the hell is that bird.
He had never seen her before and I hadn't mentioned the bird to him but he could see a good pigeon at a glance, I wish I could do that.
