The name Aquila is a girl's name meaning "eagle". Aquila and is often added to lists like Baby Names with Animal Meanings and discussed in our forums with posts like "Heaven/Hell/Purgatory Themed Girls".
From the experts:
An evocative ancient word that's used as a first name in the New Testament, among other places. It's also the name of an eagle-shaped constellation.
That said, contemporary interest in the name Aquila probably stems from its use as the name of Facebook's secretive drone project. If that takes off, and its name doesn't change, Aquila could take a hit, like Siri and Alexa before it.
