Just in time for Mother's Day, the St. Louis Zoo announced their endangered black rhino is expected to give birth any day.
The St. Louis Zoo said mother Kati Rain and father Ajabu are expecting their second child any day now.
According to the International Rhino Foundation, there are fewer than 6,000 black rhinos in the wild, classifying the species as critically endangered.
You can follow the St. Louis Zoo on social media, where they will be making animal mom themed posts all week.
