So, I was at Bird Paradise today and in one of the bins there was about 25 sun conures and about 4 GCCs. It wasn't long before I noticed the cinnamon GCC wrestling with one of the sunnies. In a couple seconds, the sunnie gave up and was simply laying on its back.Than, the GCC ran off and did the same thing to another sunnie, who reacted the same way. Then, it did it to another, then another etc.
It really shocked me to see a tiny GCC beating up all those big suns.
