I've been enjoying watching our swan neighbours this year. We have two families close by on the canal with five young between them that have survived to adolesence. One cygnet has already flown the nest, I've seen it alone and flying a short distance low over the water. But now it has disappeared, I guess to search further afield for more adolesccent swans to make a flock. I was wondering how far swans might travel to find a flock, and are they ever rejected by flocks and travel further to find another flock that might be more accepting. I wonder if the rest of the siblings will stick together in a flock or go their separate ways individually? It has also struck me that birds might pair up when they are older who are related without knowing it, I wonder if this ever happens? So many questions about these fascinating birds that have been a joy to get to know!
