An image of a blue-footed booby feeding its chick in the Galápagos Islands, taken by Fifth Form Harrovian Daniel Zhang was the subject of BBC Wildlife magazine's first social media caption competition of 2019.
Titled Inmost Feeding, the image was posted on the magazine's Facebook, Twitter and Instagram accounts. Daniel says, "Initially, the blue-footed booby mother dives at a literally breakneck speed into the sea, then stores its prey inside its throat. While feeding, the chick reaches into its mother’s gullet in order to obtain the food. I was really satisfied after taking this photo."
