Most towns in this service area have water as their defining feature. South Windsor has turf.
The Parks and Grounds operation reports 15 baseball and softball fields and 26 fields used for soccer, lacrosse, field hockey and football. Forty-one in total, plus athletic field irrigation and dams on Avery Street, Dart Hill Road and Beelzebub Road. That is a very large maintained inventory for a town of roughly 26,900 residents.
Irrigated, fertilized, closely mown grass is better forage than anything in a hedgerow, and open playing surfaces give a goose the clear sightlines it wants. Add the water: the Connecticut River on the western edge, the Scantic entering from the north to join it here, the Podunk through the east and south, and a set of brooks connecting fields, floodplain and wetland rather than isolating any one lawn.
So the goose question in South Windsor is less about a single pond and more about a network. Birds move between water and grass, and this town supplies an unusual amount of both, connected by corridors.
That is also why a program scoped to one field can disappoint. Move a flock off Rye Street and it has forty other town surfaces to consider, before you even count the school grounds and the corporate lawns. The useful question at the assessment stage is not only where the birds are standing, but which of the connected pieces you actually control.
