As I was cleaning cages today, one of my two juvi mellers that live together full time, climbed onto my arm. I placed it in a large ficus and continued to clean. The other climbed out as well so I placed it in the tree too. The first juvi flared up and did all the same crazy behaviours as my adults did when introduced. Head bobs, lobe flaps, tail lashing and lurching! The other responded by darkening its colours and charging! The one who instigated the conflict turned and ran. They have always been housed together and I never expected this reaction. They posed at each other for a few minutes till I broke it up by placing them back in their cage. I watched them for a while and all seems fine again. Odd little weirdos.
