The birds from the Muscicapidae family share a number of anatomical features, including the presence of a well-developed 10th primary feather in the wing and adaptations for insect eating. Most birds are mainly insectivores, i.e. taking their prey while airborne. Most birds have the characteristic of broad, flattened bills which are suited to catching insects. Then those species which resort to ground foraging would have have finer bills.

The number of birds available at its broadest base - worldwide there should be 297 species. This family among the largest family of birds, the main sub-group within this family is the Flycatcher.  From the "Old World"  there should be 116 species of Flycatchers. In South east Asia has  a share of 42 species.

Focusing on birds from the Muscicapidae family and those that can be seen in Malaysia, this is the concise list of Bird names with the Niltavas found among them.

There is only one Niltava that is very commonly seen in our forest and which is the Large Niltava. This bird with the profile of a large Flycatcher created the impression that Niltava as a species is a fairly large bird. In fact not. Niltavas and Flycatchers are almost alike if Niltavas are to be larger then perhaps marginally. After setting aside the odd sized Large Niltava
