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.
