"Are there any changes in the appearance of my birds droppings? Are there as many droppings as usual? Are there any unusual colors in the droppings? Look for lime green or iridescent yellow. These colors could be signs of an infection or liver problems. But don’t panic! A single dropping doesn’t mean anything. A pattern observed over a couple of days may be significant. Remember that the amount of liquid is directly related to the water content of the diet. If you are feeding primarily vegetables and fruits you will observe loose droppings. Also don’t panic if you see red droppings after feeding something red. Colored pellets may also add color to the feces. A single dropping doesn’t mean anything, but a pattern can be significant and if it persists you must call your Avian Vet."
So far:
I have only seen 2 droppings like this
Mushy, but solid

"Does my bird have a pasty vent? This is a simple exam that every bird owner can do. If your bird is used to you holding him or her upside down, you will find it really easy to examine the vent. There should be no sign of feces adhering to it or anywhere on the underside. If you’re not sure what to look for, be sure to ask your vet or breeder. Even if you can’t hold your bird on the back, get down and check out the underside. Pasty vent is usually easily observable and is almost always a sign of infection. Call your vet and discuss your observations."
This concerns me. Pinto's vent has never looked... pretty. She also occasionally has a poo stuck to the feathers around her vent, but not to often. I'm finding it very hard to examine her butt right now tho...
