I had my first loss on Friday, one of my three boys disappeared without a trace and I don't know if was a predator or if he hopefully flew away. I've gotten to thinking about things I can do to deter predators other than what I have in place already. I know that capsaicin affects mammals only as it evolved to discourage them in favor of birds, so I was thinking of getting a bunch of oil and dumping it into their playing ponds. Presumably they wouldn't feel a thing and they be weaving it into their bodies every time they splash and groom. If a mammal grabbed them and they had active capsaicin on their feathers, might they drop it? Has anyone given this a try?
