English terms for a female wolf and a female owl?

In the English language, what are the right terms for a female wolf and a female owl; perhaps "she wolf" and "owl hen"?

Are there distinct or separate words in English used for feminine? I checked in Wikipedia +other websites but found only "she-wolf" and "owl-hen".

Solution 1:

You used to have wolfess, now an archaic term. She-wolf or female wolf are the terms commonly used:

Wolfess, the medieval term for a she-wolf, is now rarely used in Present Day English except to mean a woman that is sexually aggressive.

Female owl is the more common term as far as owl is concerned; “hen owl” appears to be a more informal expression.
