White-rumped falcon 
(Cắt nhỏ họng trắng, Neohierax insignis, formerly Polihierax insignis), also known as white-rumped pygmy falcon, white-rumped falconet, Fielden's falconet,or Burmese pigmy falcon

The white-rumped falcon (Neohierax insignis) is a species of bird of prey in the family Falconidae native to Indochina. 
The bird is placed in its own monotypic genus, Neohierax.

Phylogenetic analyses of morphological characteristics found the white-rumped falcon to be basal to the Falco clade, but separate from the clade containing the pygmy falcon (or African pigmy falcon, Polihierax semitorquatus) and Microhierax (falconets or pigmy falcons).

Research in molecular genetics has also found that the white-rumped falcon is more closely related to the Falco falcons than it is to the pygmy falcon.
Female have a yellow or chestnut head, the male have white cap or grey head.

Traits:
- Yellow-eyeringed, orange-eyeringed;
- Yellow-lored, orange-lored;

Neo: From Ancient Greek νέος (néos, “new, young”).
