We know very little about the life-span and breeding behaviour of this enigmatic species. Here is a list of research papers compiled by our research team that covers some aspects of the biology and cultural significance of the species.

Adult male AGHs exhibit red and blue bare skin on the neck and throat, where the females have entirely blue facial skin and an entirely blue throat pouch.
The breeding season depends on location: West African populations (June-August), Nigerian and Ugandan populations (January), and Kenyan pairs breeding as late as November.
The nest is usually constructed in a natural cavity in a large tree, however, they may also breed in rock holes or man-made cavities that make suitable nesting sites.
