As I roamed Seymour's huge nesting colony of Blue Footed Boobies, I found one cradling a tiny chick between her large blue feet. Because of the size difference, the eye goes first to the large adult bird as it casts an eye over its sharp blue bill pointed downwards towards the chick. The bill acts as a pointer, and following its flow, we come to the tiny chick, resting comfortably under the great brown feathers of its mother's wing. This image is all about scale incongruity. It was also a difficult shot to make. I had to play with about twenty images until I was able to get one with both the mother's bill pointing downwards and the chick's body visible.
