Which specialized game species did the smaller Land Spaniels, leading to the Cocker Spaniel, focus on flushing?
Answer
Woodcock
The historical Land Spaniels were a generalized type, but specialization eventually divided them based on size and target quarry. The smaller dogs that developed from this general stock became known as Cocker Spaniels. Their specialization centered on their aptitude for navigating and flushing woodcock, a bird often concealed in dense, sometimes marshy, cover. The smaller stature of the Cocker was better suited for penetrating this thicket, whereas the larger dog, the Springer progenitor, was favored for covering more open ground and dealing with larger game.
