Robin siblings' territory

Question

Four robins are in my garden now and seem to be competing with each other for territory: lots of chasing and singing going on. Is that in fact what is happening? And how will the situation evolve?

That sounds like they are competing for territory. Ultimately one of them will end up holding the territory and the others will have to move elsewhere. They might create new territories adjacent to yours and you could see them from time to time. Some females migrate, so that could also be the reason for one or more moving on. Nice for you to have so many Robins to observe. I have the one juvenile who is currently singing loudly at the top of the holly tree. He hasn't got any rivals for his territory yet, but the constant singing reminds potential intruders that this spot is taken.
