Black-necked Swan

The Black-necked Swan is a graceful and elegant bird found throughout southern South America, especially in Patagonia. Its contrasting black neck and white plumage make it unmistakable among waterfowl. Adults have a bright red knob at the base of their bill, which is more prominent during the breeding season. These swans are mostly silent, unlike their northern relatives, and communicate with soft whistles and grunts. They are strong swimmers and often seen gliding across lakes and lagoons, sometimes accompanied by their fluffy gray cygnets riding on their backs. The species is mostly resident, though some populations may move locally in response to water levels. Black-necked Swans form monogamous pairs and are attentive parents, fiercely defending their young from potential threats.
