Who You Looking At?

All the robins are getting very territorial and there is a lot of posturing, chasing and squabbling on an hourly basis. My robin here is standing braced for yet another onslaught into his territory also wondering what I was doing standing in the utility doorway in the cold presumably too.

The main bone of contention is the bird feeder which means that they puff their chests out at even a glimpse of another robin in the vicinity. 
Even more puffed up in the Extra.
