This behavior is know as 'sunning' and is found in a great many birds. It
involves exposing as much of the feather surface,
especially the bases of the feathers (normally covered by other feathers)
to bright sun.
I have seen it over many years perhaps 10=20 times in many species During
the process the bird can seem to go into a trancelike state.
It can also occur with dust bathing (especially in quail) in my experience.
If you search 'sunning' (also called sunbathing) you can find a variety of
reasons but I don't think the true reason is known and there may
be more than one benefit.. Sunning for warmth does not agree with what
I've seen as it often happens during very weather.
