Mind Your Head!

Out on the Project Puffin Islands, arctic tern colonies are prepared to defend their own. As a group the birds rise into the air, divebombing the hapless seabird biologists who move among them to tally, weigh, and measure the growing chicks.

All the biologists wear hats, and if they happen to glance overhead, they would see this screaming mass of concerned parents, doing their best to agitate and dissuade.
