OMAHA, Neb. -- Omaha's Henry Doorly Zoo and Aquarium has some big news again. 

Zoo officials announced Wednesday that another of their African elephants, Jayei, is pregnant. 

The calf is due to arrive in fall of next year. 

It's the fourth such pregnancy Henry Doorly has announced in recent years. 

Eugenia and Sonny were born in January, while zoo officials announced a third elephant pregnancy in March. Lolly is expecting her calf in March 2023. 

Henry Doorly Officials said their four will likely account for half of the expected African elephant births in the U.S. in a two-year period.
