Understanding Bird Scent – Part 4 The Dead Bird
You’ve just made a nice on-the-wing shot on a flushing bird. The bird drops and your dog even marks the drop of the bird. You release your dog for the retrieve. What’s wrong…the dog is searching everywhere but can’t find the bird. Whether in the forested ruffed grouse woods or the prairies, we’ve all seen this scenario over and over. Why?
Understanding Bird Scent-Part 3 The Dogs Nose
The canine nose - truly one of nature's most amazing accomplishments. A dog's nose not only dominates her face, but her brain, as well. In fact, a dog relies on her sense of smell to interpret her world, in much the same way as people depend on their sight.

However, she does much of this by smelling an object or animal, not by staring at it. (Stanley Coren, Sarah Hodgson, Understanding A Dog's Sense of Smell).
Understand Bird Scent-Part 2 Diffusion
In last month's column, Understanding Bird Scent-Part 1 - The Bird, we learned about how bird scent is created. We know that there are scent rafts that create four different scent clouds that carry the scent into the atmosphere. Once the scent is airborne, there are numerous atmospheric weather conditions that affect the scent dispersal and the ability of our pointing dogs to locate a bird. In this part, of our three part series, let's examine those weather conditions that affect bird scent diffusion. We'll also look at the effect weather has on bird movement which also produces scent diffusion.

In his book Best Way To Train Your Gun Dog, Hall of Fame Trainer Delmar Smith said: "No one's ever understood one thing about scent." Add this: Odor chemistry is complex and still poorly understood. (The Science of Smell, Iowa State University May 2004). Now we can understand why few, if any, have dared enter this research field of bird scent and pointing dogs.
