You bet! Both Apollo and Bomassa have been observed climbing up a metal pole which is part of structure people call the tree. Here's the younger brother, on his way up the pole. Once he gets up there, there's nowhere to go. I think the pole might have something of a ceiling over it. So he climbs up. And he climbs down, and he climbs up, and he climbs down. Olympia, Apollo's mother, sits nearby picking seeds out of the straw and eating them.
