These guys are super cool , thanks for sharing ! <| sep |> The cage had multiple levels and a bridge connecting them . The bridge was next to the cage door and when they wanted to play with me they learnt to wait on the bridge for my hand to come in and then they would climb up my arm . If the hand never showed up they would get impatient and jump off the bridge and then run all the way back up and wait again . They knew where my hand would appear but didn ' t understand how my hand worked . <| sep |> Thanks ! IL seeked me out . It happened quite randomly , actually ! They found my YouTube channel and liked my orchestral tutorials the quality of my compositions , and thus approached me via email . Hope you ' ll learn things of value with my tutorials , feel free to drop me any questions regarding orchestral music on my channel ' s videos , if you have some !
