It's not that weird. It's a pop up blind and used often in training and occasionally in a trial. When used in a trial, it's typically on a water blind and there is not a good place to put the bird boy or plant the blind. So, for instance, the judges may say "If you get the cast off of that 3rd point out to sea and the dog is still under control, rather than watch him swim another 500 yards, we will toss a bird out to him.". I doubt this is really what the OP was talking about, but there you go.
Once the dog took the cast off that point, demonstrating commitment, the bird is thrown by a hidden thrower out into the water in front of the dog. Fun to watch.

My thoughts on planting blinds.
In training I typically like the bumpers/birds fairly easy to see. The goal of a good blind is to teach the dog to fight factors in route to the blind, not make them climb a tree, dig a hole, fight brush right at the end. Too many hunt test trainers put together relatively simple blinds then put the bird in an impossible spot at the end. I want dogs to run hard, fight factors and get the big reward at the end for doing those things. Blinds are a test of control from the mat to the bird, not just the last 10 yards.
A good blind has a beginning, middle, end. Each segment should have at least one factor showing the dogs control/trainability. The bird should be placed in a spot that doesn’t allow the dog to see it until he’s is right there and promotes control clear to the end. It should also be in a spot that has good visibility so that I as a judge can see what happens. Too often I see blinds placed where the dog goes out of sight on a blind at the end, then after being out of site for awhile the dog suddenly appears with the bird. There is no way to judge that.
Thanks Kyle and JS! Looks like it might be fun to run as well as watch.
