Very easy to identify, black-necked swans have white bodies with, of course, a black neck and head. The purpose of this carbuncle is to attract females during mating season, with males enlarging it during this time both to gain the attention of females and to intimidate other males. A smaller species at a maximum weight of 15 pounds and wingspan of 4 to 5.
They feed primarily on algae and aquatic plants, but they will also readily consume grains, grasses, and crops like potatoes and carrots. Cygnets feed on aquatic insects and fish eggs, and adults may also feed on these if vegetarian food sources in the area are limited. Native throughout Europe, mute swans are the species most often pictured when someone mentions swans.
However, in the s these birds were brought to the US to essentially adorn gardens and parks, and have long since established extensive populations and are a majorly destructive invasive species in North America. With their bright white plumage, impressive size of up to 26 pounds with a wingspan up to 8 feet, and characteristic curved necks that form a romanticized heart shape when resting with their mate, this species is hard to miss. A bright orange beak with a large black basal knob at its base makes them even easier to identify.
Both males and females have this knob, but studies have found that males will enlarge theirs during the mating season to attract females, while females enlarge theirs shortly after cygnets hatch. The latter is likely due to hormonal fluctuations and as a means of keeping the male interested in sticking around to help with raising the young.
