- Body Length (cm):
- The male (drake) of the Tufted duck measures approximately 42-48 centimeters. The female measures approximately 39-44 centimeters.

Tufted ducks are hardy, easy to manage, widely kept, good in mixed collections; they prefer large lakes with deep water for diving and natural food available. Feed as other diving and dabbling ducks (floating pellets, green food, grass) plus extra animal material if no natural food is available. Like to dive for food.
These ducks are easy to breed. They breed best on a large, deep pond or lake, not over-populated, and with natural bankside vegetation such as rushes or reeds to nest in (they may also use baskets and shallow boxes close to water). Eggs are laid from mid-May to June. These ducks brood reliably if undisturbed; ducklings may be parent reared in small enclosures (where they may be easily checked) or very large areas, otherwise hand-rearing may be used. Ducklings are not difficult to rear, although they are highly insectivorous initially and live insects are useful for feeding as well as duckweed and starter crumbs.
This species commonly hybridises, particularly with other Aythya species; hybrids also reported with Anas spp., Netta spp., Bufflehead (Bucephala albeola), Common goldeneye (Bucephala clangula).
- The female Tufted duck usually lays from 6-11 olive-grey or greenish-grey eggs and incubates them for 23-26 days.
- Artificial incubating:
The ideal relative humidity for incubating most waterfowl eggs is 55% (ground nesters) and 40% (cavity nesters). The temperature is usually 37.4°C. Set ventilation as recommended by the incubator manufacturer. Eggs must be turned, either automatically or by hand, a minimum of 4 times a day. As the duckling develops there is a loss of water from the egg and the air sac gets bigger. In normal development of an egg with a 23-26 days incubation, the air sac occupies about a third of it three days earlier. Cleanliness is vital and ideally eggs should be moved to a separate hatcher at this point, where the humidity should be increased to 65% and even higher once they have pipped internally.
- Bird banding:
- Recommended closed leg band ring size for the Tufted duck is 9 mm.The leg band ring can only be applied on a young small diving duck at around 12 days old.
- It doesn't matter what leg that you band, but it's good to have a consistent system. Suggested: Left leg = Female, Right leg = Male

Deze vogels zijn voorzien van een gesloten pootring. Het is wel verboden om deze vogels te houden die in het wild gevangen zijn. Alleen bepaalde instanties, zoals vogelasiels en vogelhospitalen, zijn bevoegd om jonge en gewonde wilde vogels te houden. Deze bescherming van vogels wordt vormgegeven door schadelijke handelingen te verbieden zoals:het doden, verwonden, vangen, bemachtigen en met het oog daarop opsporen van vogels (art. 9 Flora- en faunawet); het opzettelijk verontrusten van vogels (art. 10 Flora- en faunawet);het beschadigen, vernielen, uithalen, wegnemen en verstoren van nesten, holen of andere voortplantings- of vaste rust- of verblijfplaatsen van vogels (art. 11 Flora- en faunawet);en het zoeken, rapen, uit het nest nemen, beschadigen of vernielen van eieren van vogels (art. 12 Flora- en faunawet).
