Hormones are very apparent in our pet parrots in the spring and the fall, and it's not usually fun for anyone. If you need help dealing with your parrot's hormones; determining the triggers, etc... check out our Hormones Course.
In the meantime while you wait for that course to download, you can watch the above video and see some characteristics that you may recognize!
Hormonal triggers are important to avoid (mushy, warm foods that mimic the texture and temperature of regurgitated food is one) as well as touching your bird in places you shouldn't.
If you need more hormonal resources check out that course, it has a ton of free resource links on the page.
