I'm hoping to get some insight on the recent behaviors of my budgie "Peep". I've had him for 2 and a half years and he is molting at the moment.
For the past week or so,he has been dry regurgitating more than usual. What's odd about it though, is he does it sitting idle with no stimulant (such as a toy, mirror, bird replica toy that he plays with and tries to mate with). He makes the regurgitation motion with the stretching of the neck, but nothing comes out. He has been having bouts of this a few times a day, for about 5-10 seconds, but then he'll stop for a bit and then do it for another 5-10 seconds and so on and so forth. This whole cycle goes on for about 10 minutes or so. Afterwards, he goes back to being his normal self for the majority of the day except for these occurrences . He is normally a very energetic budgie, but this behavior as of late just seems out of ordinary to me, so I'm a bit worried.
After doing extensive research on this, there are 4 possibilities I'm finding. 1.Spring is here and he's simply being hormonal by dry regurgitating in place
2.Molting possibly having something to do with it in some way
3.Crop infection of some sort (fungal or bacterial)
4.Normal crop adjustment
In the case that it is an infection of some sort, I have started adding ACV to his water as a precaution. Otherwise, I am keeping a close eye on him to make sure nothing else is wrong. His poop is perfectly normal as well, and no changes in it. He eats well as he always has and drinks water normally. His demeanor is spunky and energetic.
I have attached a video link of him doing this behavior. You can see him start doing it right at the beginning of the video and around the :50 sec mark. At this time, him and my other bird Puff were relaxing together and both sleepy.
