Bulletin: announcing Limpy Chick and ‘Offsider’ (the male)
We – I – thought that Limpy Chick’s ‘offsider,’ who’s been here six weeks or more, was a female. I must have mistaken some feather-puffing on ‘her’ chest for the sight of a vocal sac.
Perhaps more important was ‘her’ aggressive style. Most males stand about like potted palms to during confrontations, unless the female calls for help.* But Offsider has been noticeably active in defending the perimeter (mostly against that pesky little runt bird).
We’ve also noticed that LC and Offsider turn up about the same time each morning, and from the same direction: the north west. So let’s see if that keeps happening.
Their late arrival – as opposed to, say, stepping out from behind the fig tree at first light – suggests that they roost some ways off. (There are two dams on that side.)
So, our tentative thought is: although it’s way too early, Limpy Chick has a consort. They work together aggressively against intruders. And for some reason – even though Limpy Chick was raised under the plum tree – they choose to ‘base’ themselves some distance away. (Haven’t heard her at night.)

*We aren’t quite sure what the call is, but it is as clear as day when you are watching: female arcs up against interlopers; [some vocalization or signal -- ??]; male just snaps into synchronized action. It is a fine thing to watch!
