The accessible general account establishes the species identity, distribution and the natural-history points stated above. Behaviour, diet and breeding can vary geographically, and the available source does not support adding precise Vietnam-specific measurements or nesting dates. This profile therefore retains only species-wide information that can be stated defensibly, rather than filling gaps with unsupported local claims (Wikipedia, general species account).
