Phineas is still regurgitating to my finger. He is still blowing bubbles. This phase is ongoing. We do not have an end date yet.
The regurgitation session can occur many, many times a day. Duration of each session appears to be getting longer. If I wait until he comes to a natural end rather than force him to end as I have things to do [rolls eyes!], this may mean waiting up to 25 minutes. (I usually have the TV remote control to hand).
Sometimes he attempts to clean my finger & licks it all over. Recently, after the licking, he preens my finger. As you can see from the photos below, more often than not, my finger (& sometimes hand) needs a good wash afterwards.

A most interesting incident happened a few days ago where Phineas was on top of the manor, regurgitating to my index finger. I was holding my hand up to him, resting it on the cage with my index finger out but other fingers folded back. He regurgitated as normal but then tapped on the knuckle of my middle finger. I unfolded that & he proceeded to regurgitate to that finger. Hmm… interesting.
Then he tapped on my ring finger. I unfolded that & he regurgitated to that finger. It was like he was feeding all my fingers. He seemed satisfied after doing 3 fingers & then off he went & left me with this:
