http://www.bsc-eoc.org/download/Francis-Jones-light-mortality.pdf reports on photopollution around lighthouses and states that :
Songbirds that migrate at night are attracted to these sources of light, especially under overcast or foggy weather conditions. Birds that are not killed outright by collisions with the light sources can succumb to exhaustion brought upon by prolonged fluttering around a light source or to predation upon individuals in weakened states.
A recent article in Birdguides reports on lights on off-shore vessels attracting an astonishing range of birds including water-rails and bitterns, and well as vast numbers of songbirds, often with fatal results.
And a recent book on British bird observatories reports on collisions at, for example, Bardsey. It is interesting to know that some lighthouses have nearby "safe attraction" lights to lure birds away from the danger, and to a safer landing ground.

Also on the cliffs, having started their season very early, were two Carline Thistle plants in new bud and flower.
