The oriental magpie-robin (Copsychus saularis) is a small passerine bird that was formerly classed as a member of the thrush family Turdidae, but now considered an Old World flycatcher. They are distinctive black and white birds with a long tail that is held upright as they forage on the ground or perch conspicuously. Occurring across most of the Indian subcontinent and parts of Southeast Asia, they are common birds in urban gardens as well as forests. They are particularly well known for their songs and were once popular as cagebirds. The oriental magpie-robin is the national bird of Bangladesh.

The great crested grebe (Podiceps cristatus) is a member of the grebe family of water birds noted for its elaborate mating display. The scientific name comes from Latin. Podiceps is from podicis, "vent" and pes, "foot", and is a reference to the placement of a grebe's legs towards the rear of its body, and the species name, cristatus means "crested"

The four fish owls were previously generally separated in the genus Bubo they also resemble osteologically very much – for sake of convenience. Depending on whether some little-studied tropical eagle-owls are closer to the fish-owls than to the typical eagle-owls, Ketupa might be a valid genus if these as well as the fishing owls (formerly Scotopelia) are included in it, although there are a number of osteological differences that suggest that fishing and fish owls are not directly related to each other
