Hello Birding-aus

Very interesting to see "longevity" records from the ABBS. As David eloquently stated, the average life span of birds is different. What the figures dont show is the short life span of banded birds (shortevity?). The average life span of most banded birds is less because more often they die from the trauma of capture, handling, bleeding, measuring, tagging, banding and flagging. After which the conspicuous and heavily shackled bird must survive predation, tangling and all the other hazards carrying their massive disadvantage while competing successfully.

So in the interest of presenting some balance to the figures shown so far, it may be helpful to provide similar records of "shortevity of banded birds" from the moment of capture, for which many more returns exist.

As one can see, the list does not show mortality of the many young birds that die by drowning, mismothering, crushing and predation when banders enter into colonies of Ibis, Cormorants, Terns, Pelicans and many other species including Herons and seabirds before any band is ever placed on them, but as can be clearly seen, the average life span of many banded birds is very low.
