Totally unscientifically, the form labelled 'rio ucayali' is a yellow caca with wildly large extensions on the dorsal - much larger than the captive-bred forms, and most wild forms I've seen. The tips of the extensions are red, but there's no other red on the body or fins. The tag is an attempt to differentiate them from the blue cacatuoides that comes from the same general region. There's also an aquarium strain that is yellow, but has no significant fin extensions (inbreeding?). I admit, I'm guilty of having tacked the tag on - it seemed like a step towards keeping this high dorsal strain distinct. I've seen a lot of cacatuoides and this one stuck out as something very attractive. I'd hate to see it crossed with captive form cacatuoides and then just washed out in the gene pool. Good luck with them. Gary
