Давидова нильтава Niltava davidi

A large flycatcher of tropical and subtropical forests. Male is bright blue above with a black face and orange breast and belly which becomes paler toward the vent. Rufous-bellied Niltava is extremely similar but has a bright patch on the shoulder and brighter orange underparts are uniform in intensity down to the vent. Vivid Niltava can also be similar but has an orange throat and is darker blue above. The mostly brown female is difficult to identify, but it is cooler and grayer overall compared to female Rufous-bellied. Female Fujian has a small bright white collar that is lacking in female Vivid. Gives a very high metallic “tsiiing”, as well as hard “chik” and “chek” notes.
