Photographic masses of birds in flight can be very difficult, because most of the time, some of these birds are bound to overlap each other, causing mergers and confusion. There was a massive colony of nesting Blue Boobies on this island, and during our visit, the sky seemed to be filled with them. I looked for situations where there seemed to be some spacing between the birds in the sky and after more than a hundred tries, I only found one where absolutely no birds were overlapping. This is that image, the silhouetted birds matched to a turquoise sky. I also made sure to provide a base of bushes flowing across the bottom of the frame to anchor the image.
