I've never owned a "pointing" lab, but I've had a couple that seem to be utterly mesmerized by tight sitting birds and lock up over them in a fair approximation. Maybe it's having a nose absolutely full of bird scent, I don't know. Of the current Crew members, Harley and Jetta do this. If the bird doesn't flush according to script, each will hold tight until I came right up to them. Not having a command to flush, I simply say "get em". I think I could say anything, as the sound of my voice seems to be all they need to break the trance and dive in. Harley is particularly adept at nabbing these tight sitters alive, where the rest of the Crew are happy to just flush them...
