One night on Isabella Island off Mexico, Nelson walked into a colony of nesting birds. Females were on the nests with males standing guard. The birds set up a continuous series of harsh cries and the light fascinated them like so many moths. They trooped within the light circle and commenced running in a ring about 20 feet in diameter presenting a most ludicrous sight. One bird persisted in gyrating around and over his feet!
