This vent cowl sits on top of the vent pipe to prevent birds from entering or nesting within the soil pipe, causing a blockage of the vent pipe which in turn would prevent the drainage system from operating correctly.
The vent cowl is open to the air, but has a top cover that prevents rainwater from entering the vent pipe.
This fitting is often referred to in the trade as a mushroom cowl because of its distinctive shape.
