Quail vs. Button-quail
Although the two genera of the true quails, Coturnix, and the
button-quails, Turnix,
are outwardly very similar, and therefore often listed together,
there are significant differences between them (which is the
reason why they are in different family groups here).

Call(s)/Song |
|
For this species we have recorded the following call(s)/song. The
interpretation of their meaning is our own; are welcome.
There are many fundamental differences between
true quails (Coturnix) and
button-quails (Turnix) (see
above in the "Taxonomy, classification" section).
One other is that, while in most bird species males "advertise"
(i.e. call for a partner) and declare their territory, in the case
of button-quails this is done by the females.
