High vigilance, loud voice, strong territorial instinct, aggressive towards strangers, active during the day, gets along well in a pack, but may dominate.
Chinese goose — a breeding line of the greylag goose (Anser anser). Tall-legged, slender, with a "swan" silhouette and a large fleshy knob (hock/caruncula) on the forehead. Sexual dimorphism moderate: males are larger. Male weight 4500–6500 g (ideal 5000–5500 g), females 3500–5000 g (ideal 4000–4500 g). Body length 750–950 mm, height at withers 800–1100 mm. Neck length 380–520 mm (55–60 % of body length). Beak length 95–125 mm. Shank length 110–145 mm. Knob height: 25–45 mm in males, 15–30 mm in females. Differs from the parent species by the presence of a knob, a longer thin neck with a swan-like carriage, high legs and a vertical body. Color variants: white (completely white plumage, orange beak/knob/feet) and gray/brown (gray-brown with a scaly pattern, dark stripe along the neck, dark beak/knob/feet).
