Variation on the egg-theme.

When searching for bird nests, occasionally one can find an egg that does not look like one at all. Deformation of an egg can occur for a variety of reasons (which I will not discuss here) and can result in some strange shapes. The weirdest egg I ever observed had been laid by a Black-legged Kittiwake Rissa tridactyla in its nest on the large former radar tower on Middleton Island during the summer of 2010. I have no idea what would be the cause of its remarkable shape.

Unfortunately, I only have these two photos to show and can’t retrieve any background information about the bird that laid it, though it possibly had been a bird that was included in some physiological study…

Middleton for the masses

All video footage (about 75 minutes of raw material) of a 2005 visit to Middleton Island, Gulf of Alaska, can now be found online! (update: from now on Middleton Island related subjects will be posted on a different blog: http://www.middletonisland.blogspot.com)
