Battle of the Black Flies: Day Four

This morning the black flies continue to crawl and swarm on the nesting loon. This nuisance can be enough to cause nest abandonment, and there is actually a black fly species (Similium annulus) that targets loons. Yesterday it looked at one point like there might be a second egg. If you’ve been watching at just the right time and gotten a convincing view of two or one in the deep nest bowl, let us know!
