I'm suddenly remember about some of my first birding trip. It took me a lot of time to ID the birds. Especially the Minivets, they look similar to me that time. So I think this post will help who newbies easy to id them. It may also help for some birder to study them before start the birding trip in Vietnam. So let’s see
In Vietnam, up to now 8 Minivets have been recorded which is:

Small Minivet (Pericrocotus cinnamomeus)
All the birds have long tail with almost color are Red, Yellow and Black in strong bright except Ashy Minivet just Black & White.
