Ravens on the streetlight

Where we live, we have ravens, they will be around a lot more now that the cold weather is coming, they seem to like it. Yesterday, I was sitting on the couch looking outside and I saw these 2 ravens on the light post outside our house, which is kind of like the one in the picture that I have posted. So I started watching them for awhile and they we're kind of fighting with each other. The one who was sitting right on top of the light would jump up and down, while slowly moving toward the bend in the post, so the other one had no choice but to move down, then suddenly he actually started sliding down the bend in the post. I guess you really had to see it to appreciate it, but I found it quite amusing.
