According to "Country Life" article*, coots aren't all fluffy and sweet: "... where duck nest proliferate ... will take eggs opportunistically ... and will drown duckling by towing them down by the legs." "Where food is plentiful, the chicks are fed for up to two months and may stay on parental territory for 14 weeks. However, in leaner locations, they are discouraged after the first few days and only the strongest and most persistent two or three per brood survive." * "As bald as a coot", Country Life 13.02.19
