Her name is Oolong. A female Society finch, chestnut mottled. We thought about calling her
Horlicks, since that sorta goes with Ovaltine, but a milk drink really isn't tea, so we stuck with the alliterative Oolong. Here's a fairly decent photo of Oolong and Ovaltine, sitting on the white concrete perch.

Like Ovaltine, Oolong has a ring of plucked feathers around her neck, but she's lost fewer feathers than he has. In fact, Ovaltine is a very popular fellow among the Spice finches, and I think he's lost some of his feathers to their zealous preening.
Still, Oolong and Ovaltine spend most of their time together, and this perch is one of their favorite spots. They sit and snooze, they sit and watch me; they've even had sex here a couple of times.
