'Emus pair up after year 2 correct? I've a year to find another emu so my 2 I've now don't pair up.'
The Literature on Emoooz, s., is poor. No, really: it is!
So, one reads of captive -- farmed -- emus mating at under two years. Maybe they have nothing more interesting to do.
But for wild emus (my
rothschildis), it goes like this:
life happens in seasonal cycles. For example, Dads may parent for one or almost two years. And you can mark the very last of 'black-head-ness' in 'chicks' right up to about 20 months.
But the bottom line is the seasonally-determined reality of "tentative associations>'gelling' of pair>fighting for territory>actual mating and incubation."
So, for a chick to mate
at the age of (just under)
two, it would have to be beginning the process at only about sixteen months of age. Nuh.
How it goes, though, is:
all (wild) emus have their birthday on the first of spring (I invented this notion!) They are physically mature at this age, I think; but I've written elsewhere to the effect that
wild emus are not socially mature for perhaps a year or more afterwards.
Than, halfway through that third year, they may or may not throw their hat in the ring. (This is a thing we actually have pretty good data on.) And if they fail that first year, they'll try the following year.

This photo is a treasure of mine. It shows Limpychick and Tooshtoosh and two others of the orphaned clutch of nine. These 'chicks' are about 20 months. But even though they had the whole house-clearing to themselves, they still sat together like chicks in a clutch.
