Northern gannets are special birds that don't float on the water like some birds do. Instead, they fly just above the waves, looking carefully for groups of fish swimming below. When they see a group of fish, they take turns diving straight down into the water from high up in the sky. This helps them catch lots of fish because they hunt together as a team. Each bird dives after the other, making sure they get as many fish as they can. It's like a teamwork adventure in the ocean!
