Male or Female?

    Let me start off by saying that these things are the things that are typically Characteristics
of male and female.  There have been exceptions to all of these.  It is only a generalization.
Also keep in mind that this doesn't apply if your cockatiel is
under 8 weeks, or so, of age.  Or after their first molt.

M = Male        F = Female
Characteristic  M  F
Brightly colored face  *  
Drab face colors or not so brightly colored face   *
Sings, whistles, and maybe talks *  
Quiet, but more cuddly *
Feathers surrounding vent are for the most part plain. *
Feathers surrounding vent have bars running accross them. *
    Keep the following in mind:
    Color:  keep in mind that if your cockatiel is a  pied  it is hard to visually sex.

    The only way you can be 100% sure is if you get your bird DNA sexed.
    I hope this helps!  If you have any other ways to sex cockatiels please feel free to express
them to me!
    Or if you would like to correct me you can  e-mail me.
