G'day Stephen,
Either way it would appear the only way to age an Ostrich as you describe
requires butchering it.
This has merit, especially as it removes yet another potential pest from the
wild.
Cheers Jeff.

I would imagine the only way one could age an ostrich would be by examining
feather development, bone ossification and body size of juveniles and
immatures (like any other bird species), but once they are adults it would
be difficult (impossible?) to age them. I'm happy to be corrected on that
one.
I understand that farmed ostriches can be aged according to the quality of
their meat. Not much help if you're trying to age wild ostriches from a
distance!

Similarly, it's quite possible that the original birds are producing young
every year, only to have them all taken by foxes, etc. Is it possible to
estimate the age of an ostrich from a distance?
