During koala breeding season, the dominant males will patrol their territory, going from tree to tree to check if any females are ready to mate. This tree monopoly often sees young males that have just reached sexual maturity—from 18 months old—pushed out of the mating game until they’re old and tough enough to fight back.

While it’s not clear exactly how old the pair of fighting koalas are in the video above, the unsuccessful one is definitely younger, which would explain why all it can do is sit at the base of the Eucalyptus [tree] and make its dissatisfaction known.

While it’s likely he will be bullied out of access to females until he’s about four or five years old, Alicia Alexander mentions in the video description that he did eventually gain access to that tree when the older male wasn’t looking. “The little koala won as it had claimed the the tree by nightfall,” she said.

She heard the crying, started to whimper and ran off to look for the cry-baby.

I thought it was cute that she was so worried about where the sound was coming from. She never came back, so I guess she "found" it.... or a good place to nap.

I thought it was adorable that the people offered him their tree.

with a WTF??? look on her face. The other two suddenly woke up and started swiveling their ears, looking similarly puzzled. They seemed kind of agitated so I turned the sound off.

Honestly nothing more adorable than koala bears.

Most of the time she ignores sounds of other dogs, or birds, or meowing kitties coming from the laptop, but she
got right up and came over to me and wanted to know what was going on.

someone start a gofundme page and get him his own tree
