What was the primary function that dictated the early working characteristics of the ancestors of the ESS?

Answer

Causing birds hidden in dense cover to take flight (springing game)

The defining action for the spaniels that would become the English Springer Spaniel was their unique method of hunting: 'springing' game. This involved working vigorously within dense undergrowth or cover to flush out hidden birds, causing them to fly up suddenly. This flushing action allowed the hunter to shoot them with fowling pieces. Before modern firearms, this flushing was often timed to allow the game to be caught using nets or trained falcons. This necessity to actively locate and force game into the air, rather than simply pointing or retrieving, was the core function that breeders refined over centuries, leading to the breed's characteristic drive.
