I sit and watch the birds from window and noticed that when they are all feeding from the feeders they have all started congregate together and cling to the brick wall in my garden and what looks like pecking the cement in between the brick, or like kind of scraping their beaks on it as if to sharpen their beaks. When one or two strart they all do it.

Does anyone know why they do it, what it means or what they are doing?

Thanks

Emma.
