Szechwan (Pepper) and Cinnamon were sitting next to each other on a perch, singing their Hunka Hunka Burning Love songs. To each other. The girls, meanwhile, were ignoring them on the other side of the Finsterium.
I can't really decide if the Finsters are springing into courtship activities, though. Oh, now that the wheat grass isn't evil anymore they tear that up and take the blades into nest boxes, but I think that's a toy as much as anything. And during the day they pair up for sweet moments, but then they sit together in completely different pairs a few minutes later.

For example, Szechwan (Pepper) and Oolong often sit together on the white concrete perch, picking non-existent feathers off each others' bald little heads. But lately, somebody has been kicking poor Oolong out of the communal nest box at night — rather emphatically sometimes, I'm afraid.
She might need a Society finch boyfriend or girlfriend. And
then we might see some Spring action!
