'Rogue' Robin!

Question

Hi to everyone 
 I am a newby on the forum and joined because I have a bit of a taxing problem and wondered whether anyone else had had the same experience? 
 I have a Robin in the garden behaving extremely oddly for the last week or so.He sits on a branch outside my bedroom window and sings his heart out (Very sweet),then he taps on the glass and repeatedly flies up and down it or he'll sit on the open small window and peer in at me.All very lovely but the big problem is he seems to think the whole garden belongs to him! 
 I have a large bird feeding station which I built to hold four large feeders and also have a bird table a few feet away.Usually the birds flock to have their fill from each station but now they are not allowed anywhere near either the table or the feeding station as the Robin constantly bombs any bird landing on or near it.He flies and warns them off vocally and does'nt take no for an answer!He'll sit on the top of the bird table not to eat,just to guard all the food. 
 I love all birds but I'm so upset by this behaviour as it's now that I have a group of long tailed tits waiting to feed ,as well as Great tits,blue tits,nuthatches chaffinches etc etc.It's so frustrating. 
 Can anyone suggest a remedy?If I put another station further away the Robin will only widen his patrol area as my bedroom window is quite a way from the bird feeders and he divebombs the birds arriving from it! 
 I did wonder whether the mild weather has kickstarted his mating instinct and he's advertising his masculinity so there's not much I can do but i so miss my other birdies!

Your description of the robin's behaviour, Nuthatch, makes me think that it is attacking its own reflection in the window. Robins do hold individual winter territories, and can be extremely aggressive in the autumn time as they are re-establishing themselves in the territory having been quiet while they were moulting. This bird seems to be packed full of whatever it is that encourages territorial behaviour (can't blame testosterone I suppose since both male and female robins hold territories in winter), since it is extending the treatment to anything with wings. I wonder if it would be worthwhile you taking some cling film and covering the outside of the bit of your window that the bird is tapping. This would prevent the reflection showing, and whether it helps to calm down the spitfire impersonations round the garden, it might at least silence the early morning alarm call (or tap) and let you have a lie-in once in a while. 
 The suggestions about spreading the feeding sites round the garden are definitely very good. After all, however much it tries, the robin is not going to be able to defend every site all the time, which does give other birds a chance to feed. I often get a local blackbird trying to claim ownership of a pyracantha bush in my garden. While it sort of keeps other blackbirds at bay, every year it has to concede defeat when the starling flocks get in on the act.
