About These Birds
Canada Goose
A large familiar goose with a black head and neck, white chinstrap patch, brown body, and white undertail. The most widespread goose in North America. Populations have dramatically expanded in urban parks due to adaptability. Migratory in the northern range; increasingly resident in temperate regions.
Mandarin Duck
The mandarin duck is widely considered the most beautiful duck in the world. In East Asian culture, mandarin ducks symbolize love and fidelity because they form strong pair bonds. Unlike most ducks, mandarins nest in tree holes up to 9 meters above the ground, and day-old ducklings must leap to the ground.
