Barn Swallows gathering near Boundary Bay this week.
My opinion has always been, don't worry, they'll get rid of themselves. And they always do. Here, now, family groups are gathering into large flocks. Within two weeks they'll be gone, on their way to wintering locales in South America. They are the last of the three locally common species to leave. Tree Swallows and Violet Green Swallows have already disappeared.
