Introduction

Field trial enthusiasts who follow their dogs afield can be compared with fishermen who cast their lines into the depths. Sedge-covered fields conceal the quail as effectively as water, and neither sportsman can rely on human senses alone to determine where the game is located. Rather, they both must rely on outside agents to produce results: for one it is a baited hook, for the other, natural game bird scents and a dog’s powerful sensory capabilities.

How effective can all-age bird dogs be under the grueling standards of field trial competition? To examine this question, coveys of quail containing radio collared wild birds were monitored during the National Amateur Invitational Championship, the Ames Amateur All-Age, Hobart Ames Memorial Open All-Age, and the National Championship field trials, all run on the Ames Plantation northwest of Grand Junction, Tennessee, to determine if they were detected (i.e., pointed) by the dogs during the competition.

The variable used to assess the effectiveness of the dogs in pointing the radio collared coveys was "detectability," expressed as a percentage and defined as:

Average number of productive radio collared finds (the birds were pointed) per day divided by the total number of radio collared coveys available to the dogs (i.e., within 400 meters of the centerline of the course) multiplied by 100.

Detectability was determined separately for the morning and afternoon courses.
