"Adelie penguins announcing their presence to the rookery"
Here's a image I made of Adelie Penguins announcing their presence in the rookery at Brown Bluff, Antarctica, a tuya located at the northern tip of the Antarctic Peninsula.
Nikon D4, Nikkor AF-S 70-200mm f/2.8G ED VR II, Nikon TC-14E II 1.4x Teleconverter for AF-S, Focal Length = 270mm, ISO = 400, f/7, 1/2500 sec.
Brown Bluff supports a breeding colony of about 20,000 pairs of Adelie Penguins, as well as about 550 pairs of Gentoo Penguins. Brown Bluff is an amazing location. It's fairly rare that one can land there, as more often than not the seas are too rough for zodiac landings. It's one of the more amazing locations we visited in Antarctica.
