3cy+ (female) April. Ad females generally somewhat browner, not as jet black as some males, though still cold and glossy. All PC broad and rounded, with nicely kept fringes and tips. Third outermost visible PC proportionately slightly longer, indicating growth at different rate than adjacent feathers, typically as a result of differing growth conditions during protracted moult. Juv feathers, in contrast, all grow simultaneously. [DB06360]
