bird droppings

Observation - bird droppings - UK and Ireland. Description: found a 10m by 15m area next to our pond completely covered with these droppings(at times over an inch thick!) It was during the cold spell and pond still had some running water. Pond is in an orchard so could this be geese feeding on windfall apples? D

found a 10m by 15m area next to our pond completely covered with these droppings(at times over an inch thick!) It was during the cold spell and pond still had some running water. Pond is in an orchard so could this be geese feeding on windfall apples? Droppings all over and beneath bird table which was some distance away near the house. Could it perhaps be starlings or are the droppings too big?
