Hello, in my roof, there are nesting starlings which are displaying some confusing behaviour. I have watched these starlings for the past three or so weeks tend to their young (which are very audible in the morning). Recently, they are in their most active phase, with the fledglings popping out occasionally to have a scan of the area. However, other starlings (which are nesting nearby) seem to keep flying around my roof and provoking the nest, causing a commotion of screeching. I can’t seem to figure out what these other starlings are doing? Surely, the starlings wouldn’t be attacking the nest? Thanks, Ellis
