Hello and
.
He may be going into a hormonal period. I haven't had a p'let for a long time and mine never showed any aggression the entire time I had him.
If you look up talktparrotlets.com as well, you should be able to get lots of answers from there and here. Our members are from around the world, so will pop in throughout the day. In the meantime look up in the forums section the one for
Parrotlets Place.
Talkparrotlets.com is a site dedicated to p'lets and has a huge amount of knowledgeable and experienced members as well. I will also tag a few people here that I know have p'lets.

Don't forget some will take longer to pop on due to the time zones around the world. Hope you get all the help you need.
