1. I was more interested in the kittiwakes nesting on the window ledges, and spent some time photographing them.

2. An estimated 50,000 pairs of kittiwakes breed at Bempton and thousands more breed elsewhere on Flamborough Head.

3. Farther down the coast we saw a huge kittiwake colony on an inland cliff and went to investigate.

4. Kittiwakes, seagulls that normally nest on cliffs, are now installed as regular guests on a warehouse ledge.

5. In the summer, the cliffs provide nesting ledges for millions of kittiwakes, little auks and Brunwich's guillemots.

6. The dark rock of the Wick was splashed with kittiwake droppings - streaks of whitewash - from countless cup-nests.

7. It is a sheer basalt rock cliff on which thousands of razor bills, guillemots, kittiwakes, shags and fulmars nest.
