Rathlin's birdies

You will all recall, I'm sure, Rathlin Island and it's wee birdy things...thousands of them.

Apparently the rocks are so white in summertime due to the copious amount of bird guano deposited on them...they return to their normal basalt black colour in the winter.

Aw just look at all the wee feathered things there, all sociable and everything.  Cute, aren't they?

At the beginning of the summer nesting season there must be a mad dash for the best bits of real estate on those rocks.  Some quite precarious nests there.  And can you just imagine being at the bottom of the rocks, since gravity would have the normal effect on things coming down from above...
