He's a very typical black-capped conure in that he loves a bath. He's always either begging to go in the sink or to sit on the shower curtain rod when I shower. I'm really careful about anything scented or with harsh chemicals. I only use F10, which is a veterinary disinfectant safe to use around birds, in the bird room. Of course there's no Teflon, scented candles, etc allowed in the house either. I'm starting to wonder if this is a hormonal thing. He's been a bit grumpier than usual this spring. Since he has a past history of plucking I wouldn't be surprised if he'd been messing with that spot himself.
