The individual birdmen within the Celestial Vault Divine Kingdom are slightly larger than the humans of the Celestial Profound Realm.
If the average height of a normal human male in the Cosmic Realm is about one meter seventy, then the birdmen in the Celestial Vault Divine Kingdom are nearly two meters fifty.
Moreover, they have a pair of massive wings over four meters wide spread out from their backs, which gives them enough confidence when facing Chen Zhixing.
"Chirp-chirp chirp chirp...." (Weakling, get out of the King's Royal City!)
This was the remark made by a birdman upon discovering Chen Zhixing daring to step into the nest.
In fairness, their hearts are quite kind; compared to his weak life stepping into their territory, the birdman only drove him away instead of hunting or capturing him.
"Chirp-chirp chirp chirp...." (Get out, do not trespass in the King's residence!)
