The series stars the voices of Paget Brewster, Rob Delaney, Sonia Denis, Kether Donohue, John Doman, Negin Farsad, Tony Hale and River L. Ramirez.

On October 4, 2021, Kether Donohue, the voice of Gillian, posted on Instagram that Birdgirl had been renewed for a second season.

In undoing the crimes her own father committed and combating other emerging threats of rivals while trying to balance between running the company and continuing her life as a superhero, Judy is aided by the Birdteam, an all-new crack team she forms with Meredith and other Sebben & Sebben Worldwide employees.

Reviewing the first 2 episodes, Den of Geek praises the "chaotic" pacing and characters, "sweet" backstory, and expresses hope in its potential; their review describes the show as an "exciting new Adult Swim venture that’s able to successfully carry on the unhinged atmosphere of the original Harvey Birdman while it takes the material to entirely different places.

"[21] The AV Club expressed joy towards Brewster's titular character and lamented that the supporting characters were not as interesting as those in Harvey Birdman, presumably because Birdman was contingent on the inclusion of Hanna-Barbera cartoon incidentals, whereas Birdgirl takes place in a human-centric world.
