With the genus Bhringa we enter upon those Drongos which have the outer pair of tail-feathers produced to an extravagant Length, the middle portion of the shaft being webless. The genus Bhringa differs from Dissemurus, the next genus, and the only one with which it can be confounded, by having the terminal portion of the outer tail-feathers flattened and equally webbed on both sides of the shaft. This terminal portion is about four inches in Length, and the preceding bare portion of the shaft is about three times this Length.
Jerdon was in error in stating that the Lengthened tail-feathers were present only at the breeding-season. Adults after once acquiring them, never lose them. The young acquire them at the second autumn moult.
