SAFRING Longevity record of the Glossy Ibis

Dane Paijmans(2016-08-30)

After calculating the longevities of two of the South Africa ibis species, I figured that I ought to do the rest as well. This week I will be looking at the Glossy Ibis (Plegadis falcinellus). Similar to the African Sacred and Hadeda Ibis, this record has been held for many years (1988; Ring: 710876). The individual was initially ringed on December 4th, 1971 and recovered on April 1st, 1988. The individual was found at Brakpan Dam (by a member of public; Pieter Potgieter), 9 km from its intial ringing/ hatching site at Westdene Pan, Benoni. As this individual was ringed as a chick it would not have been much older than the calculated age of 16 years 4 months. The cause of death is unknown as no details were reported at the time. As this species is known to occur in many parts of the world, I was able to find a greater longevity record from the United States of America (21 years Ref ). Greater yet was a captive bred individual that was reported to have reached 26 years 9 months and 26 days Ref. If you feel you know of an older record please contact us at SAFRING with the details.
