A lone adelie penguin calls. The Antarctic midnight sun lights up the icebergs behind.
Thanks for all your comments. The amount of interest in this one took me by surprise! The colours were amazing that night with the low sun, this particular shot was taken at 6am ..... I'd been awake all night taking photos of icebergs and penguins as the light shifted and changed in intensity. This particular penguin was very active and literally ran around calling and waving it's flippers - great fun!
