Spilornis Grey, List. Gen. B., p. 3 (1840).
Type, Falco bacha Daud, Java.
This genus is separated from other Indian genera by having a broad nuchal crest covering the whole nape. The coloration is also peculiar, brown both above and below in adults, the lower plumage ocellated with round white spots. The bill is rather long and well hooked, the festoon on the upper mandible obsolete or wanting; the nostrils are oval and oblique; the lores nearly naked. The wings are short and rounded.
The genus is confined to the Oriental Region and consists of five species, of which two occur within our limits.
