AVIS-IBIS

Birds of Indian Subcontinent

Family PARADOXORNITHIDAE

When Blanford and Oates wrote the 4 Avifauna of British India* very little had been recorded about the habits and nidification of this group of birds and it was, perhaps, on account of this that they were placed by them as a Sub-family of the Corvidae. When Harington in 1914 wrote his " Timeliides" in the Journal of the Bombay Natural History Society, he incorporated the Paradoxornithidae in this so-called Order. I can, however, see no reason for raising the Timaliidae to the rank of an Order, and though it appears that in many respects these curious birds do form a link between the Titmouses and Babblers, it appears preferable to give them the rank of a family between the two.
The genus Panurus is undoubtedly a close relation of some of our Indian Parrot-Bills, and will have to be incorporated in the same family.
The Paradoxornithidae differ from the Paridae in having a much longer first primary, the plumage very soft and lax, and in having a thick, soft crest of feathers arising from the whole crown. From the Timaliidae they differ in having the nostrils completely covered with bristles.
They are very gregarious in their habits and build cup-shaped nests in reeds, bushes, etc., whilst their eggs are of several types. The bill is very deep, being greater in depth than length in all but Conostoma. The culmen is very rounded transversely and the margins of the mandible in most species are curiously sinuate.
