Galliphasis albocristatus (now Lophura leucomelanos hamiltoni) and Galliphasis horsfieldii (now Lophura leucomelanos lathami) 
The White-Crested Kalij Pheasant and Black-Breasted Kalij Pheasant.
Pheasants and other fowl (such as domestic chickens, ducks, and geese) are some of the most well-known precocial birds. Born with open eyes and fluffy down, with “adult” (juvenile) feathers growing in shortly after birth, precocial birds generally require less care from their parents than altricial chicks. The range of precocial nature is broad, though, and precocial birds still need protection and care from their parents.
Most birds that have only one parent caring for them after hatching are precocial, and most tree-nesting birds with two parents are altricial, but there are no set lines how birds raise their young.
