Of the 3 species of albatross on Midway the Black-footed was my favourite. They were larger than the Laysan, but smaller than the Short-tailed. They walked with the head forward and low, like a gangster from the 30's. They 'moo-ed' like a cow and other times they quacked like a duck. In fact, I was sure that they were ducks in disguise!

They are more agressive than the Laysan, and I even had a small black-footed chick chase me!
The blackness of their feathers hypnotised me...
Enjoy these photos :)
