Vulture Bearded (Gypaetus barbatus) – Robert’s Ageing Chart Published 31Aug22Full Size
This cropped chart was copied from the article below by BirdLife South Africa. I have photos from Africa and China of the Bearded Vulture that may be of interest to ornithologists and researchers referencing it. To see all Bearded Vultures in the box “Enter additional search here” type Bearded Vulture and all photographed to date will be called up.
How old is that Bearded Vulture?
The Maloti-Drakensberg range that connects South Africa and Lesotho is the last and southernmost stronghold of the region’s Critically Endangered Bearded Vulture. There are fewer than 100 breeding pairs left in these mountains, which are also a vital breeding and foraging site for the Endangered Cape Vulture. In the face of climate change and global warming, this high-altitude landscape is considered a critical refuge for biodiversity such as its resident, near endemic, vultures.
The separation of ages is not only of interest, but is also important when assessing the breeding and survival success of the Bearded Vulture. To help observers determine the age of the birds seen, an illustrated chart has been produced by the John Voelcker Bird Book Fund. By tracking changes in underwing pattern and facial coloration it shows the seven years from juvenile to adult. This will assist interested people who wish to get better acquainted with this awe-inspiring species, especially at the viewing and photographic hides and for research.
The John Voelcker Bird Book Fund acknowledges with gratitude guidance given by Dr Sonja Krüger of Ezemvelo KZN Wildlife and the African Bird of Prey Sanctuary in KwaZulu-Natal.
