Longevity record of the Hadeda Ibis

Dane Paijmans(2016-08-19)

Continuing on with our ibis longevities, I thought we could take a look at my personal 3 am alarm clock; the Hadeda Ibis (Bostrychia hagedash). The longevity record calculated for this species is another older one from 1999 (Ring: 836378). This individual was initially ringed on February 20th, 1989 and recovered on July 11th, 1999. It was initially ringed as a juvenile at CROW (Centre for Rehabilitation of Wildlife) in Yellowwood Park, KZN. After being attacked by a dog, it was then returned to CROW over ten years later. Through some great work and effort it was rehabilitated and released back into the wild. Since its release this individual has not been reported again. The next oldest individual we have record of reached 9 years old, with a number of other records falling into this similar age group. As a fair number of chicks have been ringed since 2006, for a colour ringing project in the southern suburbs, Cape Town (Colour-ringing of Hadeda Ibis on the Cape Peninsula), there should be more decade old individuals appearing, and this longevity may soon be bested.
If you feel you know of an older record please contact us at SAFRING with the details.
