How to tell cockatiel genders apart

It will be difficult to tell 'tiel genders apart until they first molt at about 6 to 9 months of age.
Gray colored 'tiels are quite easily sexed once their adult plumage has grown in.
Male 'tiel faces have a more defined coloring of yellow than females-who only usually have pale traces of yellow on their face. Male 'tiels also have a more solid gray coat than females.
Here are a few more ways to tell males and females apart:


-Males tend to whistle a lot
-Females are generally quieter than males
-Females tend to screech
-females are more likely to hiss/bite if untamed
-Males tend to show off and strut around

Hope this helped! ^^
