Rare visitor

It's very interesting watching the interaction between the different birds - as I've been doing recently.  The crow is a very rare visitor to the back garden although I often see them in the front garden and on the roof.  The pigeons, although large,  are a bit aggressive towards each other at times, but will leave the smaller birds like robins alone and let them feed alongside them.  Today I could see that this crow was higher up the rankings than the pigeons as they quietly moved out of the way and allowed the crow to have the pickings of the crumbs and seeds I had thrown onto the grass.
