A small, dazzlingly ornamental perching duck kept by waterfowl aviculturists rather than as livestock. Hardy and undemanding in a well-planted aviary, but strong fliers that must be pinioned or kept in covered pens.

Part of the Ducks
Domestic waterfowl kept for eggs, meat, pest control, and companionship. Most breeds descend from the wild mallard (Muscovies are the exception) and share a love of water, a flock-loving nature, and famous weather-hardiness.
From the minimum an animal needs to be kept humanely, up to the ideal setup. Bigger is almost always better — minimums are floors, not targets.

Minimum
Aviary + pond + nest box
8 sq ft shelter + 20 sq ft covered aviary / pair + pool
Mandarins are small ornamental woodland ducks that fly strongly and nest in tree cavities. A welfare minimum is 8 sq ft of shelter and 20 sq ft of fully roofed aviary per pair, with a pool ≥ 50 gal, an elevated nest box (12 × 12 × 24 in, 10 ft off ground), grit, calcium, clean water, and ½ in hardware cloth. Permit-regulated in most regions.

Recommended
Covered aviary + planted pond
12 sq ft shelter + 30 sq ft covered aviary / pair + pond
A 12 sq ft per pair shelter with a 30+ sq ft per pair roofed aviary over a planted pond gives Mandarins room to swim, perch, and nest. Provide overhead branches, multiple elevated nest boxes, varied aquatic plants, and a soft-floor landing area — they hit the water head-first when alarmed.

Ideal
Woodland aviary + natural pond
20 sq ft shelter + 50+ sq ft covered aviary / pair + pond
A 20 sq ft per pair shelter with a 50+ sq ft per pair fully roofed woodland aviary over a natural-edge pond is the welfare ideal. Plant climbing willow, dogwood, and reeds around the water, provide multiple elevated nest boxes, and maintain a winter heated waterer — Mandarin pairs bond for life and need calm, naturalistic surroundings.
Life & growth stages
How this animal changes through its life — each stage often has its own care, diet and space needs.

Egg
Birds develop inside a hard-shelled egg incubated by the parent(s). Egg size, shell color, and clutch size vary by species; the embryo develops over days to weeks before hatching.
Photo coming soon
Hatchling / Chick
Hatchlings are either altricial — naked, blind, and dependent on parents (typical of parrots and songbirds) — or precocial — downy, mobile, and self-feeding soon after hatching (typical of poultry and waterfowl). Down gives way to the first feathers.
Photo coming soon
Juvenile / Fledgling
Fledglings grow in their juvenile plumage and begin to fly and feed themselves, though they may still beg from parents at first. Juvenile feathering is often duller than the adult and is replaced as the bird matures.
Adult
Adults attain full body size and mature plumage, and are capable of breeding. Many species show distinct adult coloration, and in sexually dimorphic birds males and females differ in plumage, size, or markings.

Color & pattern variants
Natural variants occur in the wild; selectively bred (man-made) variants were developed in captivity.
Mandarins are **ornamental waterfowl** kept in a **planted aviary or pond pen** with **clean water for swimming**, **dense cover/plants**, and — because they're **cavity nesters** — **raised nest boxes** with a ramp or low entry. They are **agile, strong fliers**, so they must be kept in a **covered (netted/roofed) pen** or be **pinioned/wing-clipped** to prevent escape (escaped birds establish feral populations in some regions). Provide a sheltered, dry land area, shade, and gentle pond edges/ramps. They are quite **cold-hardy** (kept outdoors year-round in temperate climates with open water and dry shelter), but appreciate protection from extreme cold and predators.
Substrate
Provide a **dry, well-drained land area** (sand, gravel, or short turf) beside **clean swimming water**, with **planting and cover** around the pond. Nest boxes are bedded with **wood shavings**. Around water use **gravel or sand** for drainage. Keep the land area and shelter dry to prevent foot problems and aspergillosis. Live plants give them cover and foraging.
Equipment & setup
Key gear: a **covered/netted aviary or pond pen**, a **clean pond or pool** with a pump/filter or regular changes, **raised nest boxes** with ramps, **shelter**, and **shallow drinkers/feeders**. Because they fly so well, **pinioning (done as day-olds) or wing-clipping** is standard to keep collections contained where escape into the wild is a concern. Ducklings need a **brooder with heat plate** and shallow water. In cold climates, keep at least part of the water open and provide a dry windbreak; supplemental heat is rarely needed.
Diet
Feed a **waterfowl/duck maintenance pellet** plus **mixed grains (wheat, etc.)** and greens; in the wild they eat seeds, acorns, aquatic plants, and insects, so variety and some live food (mealworms) keep them in good condition, especially during breeding. Provide **grit** and **oyster shell** for laying hens. Ducklings need a **niacin-adequate starter**. As with all ducks, **water beside feed** lets them feed safely. They appreciate floating duckweed and aquatic plants to forage on. Avoid bread.
Behavior & temperament
Mandarins are **shy, ornamental perching ducks** best kept as **pairs or small groups**; drakes are famously beautiful, and they often form strong seasonal pair bonds. They **perch and roost off the ground** (unusual for ducks) and **nest in tree cavities or boxes**, with ducklings making a dramatic leap from the nest box to follow the hen. They are peaceful, quiet (soft whistles and grunts rather than loud quacking), and generally non-aggressive, mixing well in mixed-species waterfowl collections. They are wary of people and not typically hand-tame.
Health
Hardy in clean conditions; main concerns are the usual waterfowl issues — **wet feather** from dirty water, **bumblefoot**, **parasites**, **botulism** from stagnant water, and **aspergillosis** (a respiratory fungal disease) in damp, moldy conditions. **Ducklings are fragile** (chilling, drowning) and need shallow, drown-proof water and a way out of any deep water and out of the nest box. Keep water clean and the land area dry. They can carry **avian influenza**; practice biosecurity. An avian/waterfowl-experienced vet is ideal.
Tips, DIY & hacks
Mandarins are kept as **living jewels** in waterfowl collections — pair a stunning drake with a hen in a **planted, covered pond pen**. Provide **raised nest boxes** and you may be rewarded with ducklings leaping to follow the hen. Keep water **clean** (their biggest health lever) and the land area **dry** to prevent foot and fungal problems. They **fly strongly**, so net the pen or pinion birds to prevent escapes and feral establishment. They mix peacefully in **multi-species waterfowl displays**. In the US they're generally legal to keep as captive-bred ornamental waterfowl, but **confirm state rules** for non-native waterfowl and any pinioning/escape regulations.
