The Sittidæ, or Nuthatches, are another small family of tree-creeping birds, whose distribution is very similar to that of the Certhiidæ, but with a more uniform range over the Oriental region, and extending to New Zealand and Madagascar. The genera are as follows:—
Sitta (17 sp.), Palæarctic and Nearctic regions to South India and Mexico; Dendrophila (2 sp.), Ceylon and India to Burmah and Malaya; Hypherpes (1 sp.), Madagascar; Sittella (6 sp.), Australia and New Guinea. Acanthisitta (1 sp.) and Xenicus (4 sp.), New Zealand, are placed with some doubt in this family.

The Paridæ, or Tits, are very abundant in the Nearctic and Palæarctic regions; many fine species are found in the Himalayas, but they are sparingly scattered through the Ethiopian, Oriental, and Australian regions. The genera usually admitted into this family are the following, but the position of some of them, especially of the Australian forms, is doubtful.
(864—867 870) Parus (46 sp.), North America, from Mexico, Palæarctic, and Oriental regions, Tropical and South Africa; (868 869) Lophophanes (10 sp.), Europe, the Higher Himalayas to Sikhim, North America to Mexico; Acredula = Orites (6 sp.), Palæarctic region; Melanochlora (2 sp.), Nepal to Sumatra; Psaltria (1 sp.), Java; Psaltriparus (3 sp.), Guatemala to California, and Rocky Mountains; Auriparus (1 sp.), Rio Grande; (881 882) Parisoma (5 sp.), Tropical and South Africa; (883 884) Ægithalus (6 sp.), South-east Europe to South Africa; (885 889) Ægithaliscus (6 sp.), Afghanistan and Himalayas to Amoy; Cephalopyrus (1 sp.), North-west Himalayas; Sylviparus (1 sp.), Himalayas and Central India; Certhiparus (2 sp.), New Zealand; (879 880) Sphenostoma (2 sp.), East and South Australia.

The Liotrichidæ, or Hill-Tits, are small, active, delicately-coloured birds, almost confined to the Himalayas and their extension eastward to China. They are now generally admitted to form a distinct family. The genera are distributed as follows:
