Which birds prey on African gray parrots?

Created from Britannica articles using AI. AI can make mistakes, so verify using Britannica articles.

African gray parrots are preyed upon by various raptors, including the palm-nut vulture (Gypohierax angolensis). Additionally, monkeys are known to prey on the parrots' eggs and nestlings.1

To mitigate these threats, African gray parrots often choose to roost on river or coastal islands or near clearings. When a flock detects a predator, they may fall silent before suddenly breaking cover and screaming loudly to alert others.1
