Is this just discoloration?

[Lovie]

I noticed my lovebird's foot is a little yellow-tinged, and I'm trying to figure out if I should be worried or not... opinions are appreciated.

Has she got any toys/food that contain yellow dyes?
Are there any signs of illness, such as unusual poo, poor eyes and/or nostrils, messy feathers?

Psittacosis will cause jaundice, but not localised like this - this just looks like discolouration to me.

One of my Macaws has been walking around with a purple foot for three days now, thanks to a smushed blackberry.

My Cockatoos pristine blinding whitness is smudged with a pink streak down her left wing, from a dyed wooden toy she leaned against after a shower.

I agree with the other poster, that this is probably from food or a toy

I suppose maybe it is just from food or a toy. I'll keep an eye out. Thank you!
