Very nicely done as all of these have been, Peter. I love your choice of titles in this series. That’s a very tightly packed nesting colony, but they do seem to be pretty social birds.
Such interesting looking birds, full of character. And they seem to be really social. My only suggestion would be to crop the left side of the top picture, since that empty space doesn’t seem to be contributing to the picture, and the crop would emphasize how they are all bunched up tightly.
