Least terns eggs in the nest of a Piping Plover. June 16, 1983 on the Missouri National Recreation River. This picture was published in a seasonal report for American Birds. Notice all the tracks on the right side of this nest, which based on this image was well-cared-for, as the eggs are all carefully arranged and their is nothing haphazard to convey that this was nothing other than a typical nest, shown further because of its distinct character.
