Well, as for me, at times when I had a few dozen inside Pigeons, all self sufficient...I could leave them for four or five days...making sure there was ample Water ( one Gallon Gravity type waterers ) and, plenty of feed in the feed bins.
No problems.
One or two or three or five Birds, one could arrange to be gone much longer.
Get one of those Gallon Waterers, or even get two of them, the plastic kind...tape a Plate or Pizza Tin on the top so if he perches on it, he can not poop into it...
Have it filled with mild ACV-Water.
Make sure he knows how to drink from it.
That, and small Bowls of Seeds with Grit, say, one Bowl for each day you will be gone...you could probably be fine being gone a full week or ten days.
Ideally, a trusted friend would be called upon to look in on the Bird, and make sure all is well...of course.
